Variables ¶
var EvalDataForNoInstanceKey = InstanceKeyEvalData{}
EvalDataForNoInstanceKey is a value of InstanceKeyData that sets no instance key values at all, suitable for use in contexts where no keyed instance is relevant.
var GraphTypeMap = map[string]GraphType{ "apply": GraphTypeApply, "plan": GraphTypePlan, "plan-destroy": GraphTypePlanDestroy, "validate": GraphTypeValidate, "eval": GraphTypeEval, }
GraphTypeMap is a mapping of human-readable string to GraphType. This is useful to use as the mechanism for human input for configurable graph types.
Functions ¶
func CheckCoreVersionRequirements ¶ added in v0.12.0
func CheckCoreVersionRequirements(config *configs.Config) tfdiags.Diagnostics
CheckCoreVersionRequirements visits each of the modules in the given configuration tree and verifies that any given Core version constraints match with the version of Terraform Core that is being used.
The returned diagnostics will contain errors if any constraints do not match. The returned diagnostics might also return warnings, which should be displayed to the user.
func GraphDot ¶
GraphDot returns the dot formatting of a visual representation of the given Terraform graph.
func ReferencesFromConfig ¶ added in v0.7.8
func ReferencesFromConfig(body hcl.Body, schema *configschema.Block) []*addrs.Reference
ReferencesFromConfig returns the references that a configuration has based on the interpolated variables in a configuration.
Types ¶
type ApplyGraphBuilder ¶ added in v0.7.8
type ApplyGraphBuilder struct { // Config is the configuration tree that the diff was built from. Config *configs.Config // Changes describes the changes that we need apply. Changes *plans.Changes // State is the current state State *states.State // Components is a factory for the plug-in components (providers and // provisioners) available for use. Components contextComponentFactory // Schemas is the repository of schemas we will draw from to analyse // the configuration. Schemas *Schemas // Targets are resources to target. This is only required to make sure // unnecessary outputs aren't included in the apply graph. The plan // builder successfully handles targeting resources. In the future, // outputs should go into the diff so that this is unnecessary. Targets []addrs.Targetable // Validate will do structural validation of the graph. Validate bool }
ApplyGraphBuilder implements GraphBuilder and is responsible for building a graph for applying a Terraform diff.
Because the graph is built from the diff (vs. the config or state), this helps ensure that the apply-time graph doesn't modify any resources that aren't explicitly in the diff. There are other scenarios where the diff can be deviated, so this is just one layer of protection.
func (*ApplyGraphBuilder) Build ¶ added in v0.7.8
func (b *ApplyGraphBuilder) Build(path addrs.ModuleInstance) (*Graph, tfdiags.Diagnostics)
See GraphBuilder
func (*ApplyGraphBuilder) Steps ¶ added in v0.7.8
func (b *ApplyGraphBuilder) Steps() []GraphTransformer
See GraphBuilder
type AttachDependenciesTransformer ¶ added in v0.12.14
type AttachDependenciesTransformer struct { }
AttachDependenciesTransformer records all resource dependencies for each instance, and attaches the addresses to the node itself. Managed resource will record these in the state for proper ordering of destroy operations.
func (AttachDependenciesTransformer) Transform ¶ added in v0.12.14
func (t AttachDependenciesTransformer) Transform(g *Graph) error
type AttachResourceConfigTransformer ¶ added in v0.7.8
type AttachResourceConfigTransformer struct {
Config *configs.Config // Config is the root node in the config tree
}
AttachResourceConfigTransformer goes through the graph and attaches resource configuration structures to nodes that implement GraphNodeAttachManagedResourceConfig or GraphNodeAttachDataResourceConfig.
The attached configuration structures are directly from the configuration. If they're going to be modified, a copy should be made.
func (*AttachResourceConfigTransformer) Transform ¶ added in v0.7.8
func (t *AttachResourceConfigTransformer) Transform(g *Graph) error
type AttachSchemaTransformer ¶ added in v0.12.0
AttachSchemaTransformer finds nodes that implement GraphNodeAttachResourceSchema, GraphNodeAttachProviderConfigSchema, or GraphNodeAttachProvisionerSchema, looks up the needed schemas for each and then passes them to a method implemented by the node.
func (*AttachSchemaTransformer) Transform ¶ added in v0.12.0
func (t *AttachSchemaTransformer) Transform(g *Graph) error
type AttachStateTransformer ¶ added in v0.7.8
AttachStateTransformer goes through the graph and attaches state to nodes that implement the interfaces above.
func (*AttachStateTransformer) Transform ¶ added in v0.7.8
func (t *AttachStateTransformer) Transform(g *Graph) error
type BasicGraphBuilder ¶ added in v0.4.0
type BasicGraphBuilder struct { Steps []GraphTransformer Validate bool // Optional name to add to the graph debug log Name string }
BasicGraphBuilder is a GraphBuilder that builds a graph out of a series of transforms and (optionally) validates the graph is a valid structure.
func (*BasicGraphBuilder) Build ¶ added in v0.4.0
func (b *BasicGraphBuilder) Build(path addrs.ModuleInstance) (*Graph, tfdiags.Diagnostics)
type BuiltinEvalContext ¶ added in v0.4.0
type BuiltinEvalContext struct { // StopContext is the context used to track whether we're complete StopContext context.Context // PathValue is the Path that this context is operating within. PathValue addrs.ModuleInstance // Evaluator is used for evaluating expressions within the scope of this // eval context. Evaluator *Evaluator // Schemas is a repository of all of the schemas we should need to // decode configuration blocks and expressions. This must be constructed by // the caller to include schemas for all of the providers, resource types, // data sources and provisioners used by the given configuration and // state. // // This must not be mutated during evaluation. Schemas *Schemas // VariableValues contains the variable values across all modules. This // structure is shared across the entire containing context, and so it // may be accessed only when holding VariableValuesLock. // The keys of the first level of VariableValues are the string // representations of addrs.ModuleInstance values. The second-level keys // are variable names within each module instance. VariableValues map[string]map[string]cty.Value VariableValuesLock *sync.Mutex Components contextComponentFactory Hooks []Hook InputValue UIInput ProviderCache map[string]providers.Interface ProviderInputConfig map[string]map[string]cty.Value ProviderLock *sync.Mutex ProvisionerCache map[string]provisioners.Interface ProvisionerLock *sync.Mutex ChangesValue *plans.ChangesSync StateValue *states.SyncState RefreshStateValue *states.SyncState InstanceExpanderValue *instances.Expander // contains filtered or unexported fields }
BuiltinEvalContext is an EvalContext implementation that is used by Terraform by default.

type CBDEdgeTransformer ¶ added in v0.7.8
type CBDEdgeTransformer struct { // Module and State are only needed to look up dependencies in // any way possible. Either can be nil if not availabile. Config *configs.Config State *states.State // If configuration is present then Schemas is required in order to // obtain schema information from providers and provisioners so we can // properly resolve implicit dependencies. Schemas *Schemas }
CBDEdgeTransformer modifies the edges of CBD nodes that went through the DestroyEdgeTransformer to have the right dependencies. There are two real tasks here:
With CBD, the destroy edge is inverted: the destroy depends on the creation.
A_d must depend on resources that depend on A. This is to enable the destroy to only happen once nodes that depend on A successfully update to A. Example: adding a web server updates the load balancer before deleting the old web server.
This transformer requires that a previous transformer has already forced create_before_destroy on for nodes that are depended on by explicit CBD nodes. This is the logic in ForcedCBDTransformer, though in practice we will get here by recording the CBD-ness of each change in the plan during the plan walk and then forcing the nodes into the appropriate setting during DiffTransformer when building the apply graph.
func (*CBDEdgeTransformer) Transform ¶ added in v0.7.8
func (t *CBDEdgeTransformer) Transform(g *Graph) error
type CallbackUIOutput ¶ added in v0.3.0

func (o *CallbackUIOutput) Output(v string)
type CloseProviderTransformer ¶ added in v0.6.0
type CloseProviderTransformer struct{}
CloseProviderTransformer is a GraphTransformer that adds nodes to the graph that will close open provider connections that aren't needed anymore. A provider connection is not needed anymore once all depended resources in the graph are evaluated.
func (*CloseProviderTransformer) Transform ¶ added in v0.6.0
func (t *CloseProviderTransformer) Transform(g *Graph) error
type CloseProvisionerTransformer ¶ added in v0.6.0
type CloseProvisionerTransformer struct{}
CloseProvisionerTransformer is a GraphTransformer that adds nodes to the graph that will close open provisioner connections that aren't needed anymore. A provisioner connection is not needed anymore once all depended resources in the graph are evaluated.

type ConcreteResourceInstanceNodeFunc ¶ added in v0.12.0
type ConcreteResourceInstanceNodeFunc func(*NodeAbstractResourceInstance) dag.Vertex

ConcreteResourceNodeFunc is a callback type used to convert an abstract resource to a concrete one of some type.
type ConfigTransformer ¶ added in v0.4.0
type ConfigTransformer struct { Concrete ConcreteResourceNodeFunc // Module is the module to add resources from. Config *configs.Config // Mode will only add resources that match the given mode ModeFilter bool Mode addrs.ResourceMode }
ConfigTransformer is a GraphTransformer that adds all the resources from the configuration to the graph.
The module used to configure this transformer must be the root module.
Only resources are added to the graph. Variables, outputs, and providers must be added via other transforms.
Unlike ConfigTransformerOld, this transformer creates a graph with all resources including module resources, rather than creating module nodes that are then "flattened".
func (*ConfigTransformer) Transform ¶ added in v0.4.0
func (t *ConfigTransformer) Transform(g *Graph) error
type Context ¶
type Context struct {
// contains filtered or unexported fields
}
Context represents all the context that Terraform needs in order to perform operations on infrastructure. This structure is built using NewContext.
func NewContext ¶
func NewContext(opts *ContextOpts) (*Context, tfdiags.Diagnostics)
NewContext creates a new Context structure.
Once a Context is created, the caller must not access or mutate any of the objects referenced (directly or indirectly) by the ContextOpts fields.
If the returned diagnostics contains errors then the resulting context is invalid and must not be used.
func (*Context) Apply ¶
func (c *Context) Apply() (*states.State, tfdiags.Diagnostics)
Apply applies the changes represented by this context and returns the resulting state.
Even in the case an error is returned, the state may be returned and will potentially be partially updated. In addition to returning the resulting state, this context is updated with the latest state.
If the state is required after an error, the caller should call Context.State, rather than rely on the return value.
TODO: Apply and Refresh should either always return a state, or rely on the
State() method. Currently the helper/resource testing framework relies on the absence of a returned state to determine if Destroy can be called, so that will need to be refactored before this can be changed.
func (*Context) Config ¶ added in v0.12.0
Config returns the configuration tree associated with this context.
func (*Context) Eval ¶ added in v0.12.0
func (c *Context) Eval(path addrs.ModuleInstance) (*lang.Scope, tfdiags.Diagnostics)
Eval produces a scope in which expressions can be evaluated for the given module path.
This method must first evaluate any ephemeral values (input variables, local values, and output values) in the configuration. These ephemeral values are not included in the persisted state, so they must be re-computed using other values in the state before they can be properly evaluated. The updated values are retained in the main state associated with the receiving context.
This function takes no action against remote APIs but it does need access to all provider and provisioner instances in order to obtain their schemas for type checking.
The result is an evaluation scope that can be used to resolve references against the root module. If the returned diagnostics contains errors then the returned scope may be nil. If it is not nil then it may still be used to attempt expression evaluation or other analysis, but some expressions may not behave as expected.
func (*Context) Graph ¶
func (c *Context) Graph(typ GraphType, opts *ContextGraphOpts) (*Graph, tfdiags.Diagnostics)
Graph returns the graph used for the given operation type.
The most extensive or complex graph type is GraphTypePlan.
func (*Context) Import ¶ added in v0.7.0
func (c *Context) Import(opts *ImportOpts) (*states.State, tfdiags.Diagnostics)
Import takes already-created external resources and brings them under Terraform management. Import requires the exact type, name, and ID of the resources to import.
This operation is idempotent. If the requested resource is already imported, no changes are made to the state.
Further, this operation also gracefully handles partial state. If during an import there is a failure, all previously imported resources remain imported.
func (*Context) Input ¶ added in v0.3.0
func (c *Context) Input(mode InputMode) tfdiags.Diagnostics
Input asks for input to fill unset required arguments in provider configurations.
This modifies the configuration in-place, so asking for Input twice may result in different UI output showing different current values.
func (*Context) Plan ¶
func (c *Context) Plan() (*plans.Plan, tfdiags.Diagnostics)
Plan generates an execution plan for the given context, and returns the refreshed state.
The execution plan encapsulates the context and can be stored in order to reinstantiate a context later for Apply.
Plan also updates the diff of this context to be the diff generated by the plan, so Apply can be called after.
func (*Context) Refresh ¶
func (c *Context) Refresh() (*states.State, tfdiags.Diagnostics)
Refresh goes through all the resources in the state and refreshes them to their latest state. This is done by executing a plan, and retaining the state while discarding the change set.
In the case of an error, there is no state returned.
func (*Context) SetVariable ¶ added in v0.4.0
SetVariable sets a variable after a context has already been built.
func (*Context) State ¶ added in v0.9.0
State returns a copy of the current state associated with this context.
This cannot safely be called in parallel with any other Context function.
func (*Context) Stop ¶
func (c *Context) Stop()
Stop stops the running task.
Stop will block until the task completes.
func (*Context) Validate ¶
func (c *Context) Validate() tfdiags.Diagnostics
Validate performs semantic validation of the configuration, and returning any warnings or errors.
Syntax and structural checks are performed by the configuration loader, and so are not repeated here.
func (*Context) Variables ¶ added in v0.4.0
func (c *Context) Variables() InputValues
Variables will return the mapping of variables that were defined for this Context. If Input was called, this mapping may be different than what was given.
type ContextGraphOpts ¶ added in v0.5.0
type ContextGraphWalker ¶ added in v0.4.0
type ContextGraphWalker struct { NullGraphWalker // Configurable values Context *Context State *states.SyncState // Used for safe concurrent access to state RefreshState *states.SyncState // Used for safe concurrent access to state Changes *plans.ChangesSync // Used for safe concurrent writes to changes InstanceExpander *instances.Expander // Tracks our gradual expansion of module and resource instances Operation walkOperation StopContext context.Context RootVariableValues InputValues // This is an output. Do not set this, nor read it while a graph walk // is in progress. NonFatalDiagnostics tfdiags.Diagnostics // contains filtered or unexported fields }
ContextGraphWalker is the GraphWalker implementation used with the Context struct to walk and evaluate the graph.
func (*ContextGraphWalker) EnterPath ¶ added in v0.5.0
func (w *ContextGraphWalker) EnterPath(path addrs.ModuleInstance) EvalContext
func (*ContextGraphWalker) EvalContext ¶ added in v0.13.0
func (w *ContextGraphWalker) EvalContext() EvalContext
func (*ContextGraphWalker) Execute ¶ added in v0.14.0
func (w *ContextGraphWalker) Execute(ctx EvalContext, n GraphNodeExecutable) tfdiags.Diagnostics
type ContextMeta ¶ added in v0.9.0
type ContextMeta struct { Env string // Env is the state environment // OriginalWorkingDir is the working directory where the Terraform CLI // was run from, which may no longer actually be the current working // directory if the user included the -chdir=... option. // // If this string is empty then the original working directory is the same // as the current working directory. // // In most cases we should respect the user's override by ignoring this // path and just using the current working directory, but this is here // for some exceptional cases where the original working directory is // needed. OriginalWorkingDir string }
ContextMeta is metadata about the running context. This is information that this package or structure cannot determine on its own but exposes into Terraform in various ways. This must be provided by the Context initializer.
type ContextOpts ¶
type ContextOpts struct { Config *configs.Config Changes *plans.Changes State *states.State Targets []addrs.Targetable Variables InputValues Meta *ContextMeta Destroy bool SkipRefresh bool Hooks []Hook Parallelism int Providers map[addrs.Provider]providers.Factory Provisioners map[string]provisioners.Factory // If non-nil, will apply as additional constraints on the provider // plugins that will be requested from the provider resolver. ProviderSHA256s map[string][]byte // If non-nil, will be verified to ensure that provider requirements from // configuration can be satisfied by the set of locked dependencies. LockedDependencies *depsfile.Locks // Set of providers to exclude from the requirements check process, as they // are marked as in local development. ProvidersInDevelopment map[addrs.Provider]struct{} UIInput UIInput }
ContextOpts are the user-configurable options to create a context with NewContext.
type CountBoundaryTransformer ¶ added in v0.7.8
CountBoundaryTransformer adds a node that depends on everything else so that it runs last in order to clean up the state for nodes that are on the "count boundary": "foo.0" when only one exists becomes "foo"
func (*CountBoundaryTransformer) Transform ¶ added in v0.7.8
func (t *CountBoundaryTransformer) Transform(g *Graph) error
type DestroyEdgeTransformer ¶ added in v0.7.8
type DestroyEdgeTransformer struct { // These are needed to properly build the graph of dependencies // to determine what a destroy node depends on. Any of these can be nil. Config *configs.Config State *states.State // If configuration is present then Schemas is required in order to // obtain schema information from providers and provisioners in order // to properly resolve implicit dependencies. Schemas *Schemas }
DestroyEdgeTransformer is a GraphTransformer that creates the proper references for destroy resources. Destroy resources are more complex in that they must be depend on the destruction of resources that in turn depend on the CREATION of the node being destroy.
That is complicated. Visually:
B_d -> A_d -> A -> B
Notice that A destroy depends on B destroy, while B create depends on A create. They're inverted. This must be done for example because often dependent resources will block parent resources from deleting. Concrete example: VPC with subnets, the VPC can't be deleted while there are still subnets.
func (*DestroyEdgeTransformer) Transform ¶ added in v0.7.8
func (t *DestroyEdgeTransformer) Transform(g *Graph) error
type DestroyPlanGraphBuilder ¶ added in v0.7.8
type DestroyPlanGraphBuilder struct { // Config is the configuration tree to build the plan from. Config *configs.Config // State is the current state State *states.State // Components is a factory for the plug-in components (providers and // provisioners) available for use. Components contextComponentFactory // Schemas is the repository of schemas we will draw from to analyse // the configuration. Schemas *Schemas // Targets are resources to target Targets []addrs.Targetable // Validate will do structural validation of the graph. Validate bool }
DestroyPlanGraphBuilder implements GraphBuilder and is responsible for planning a pure-destroy.
Planning a pure destroy operation is simple because we can ignore most ordering configuration and simply reverse the state.

EvalContext is the interface that is given to eval nodes to execute.
type EvalGraphBuilder ¶ added in v0.12.0
type EvalGraphBuilder struct { // Config is the configuration tree. Config *configs.Config // State is the current state State *states.State // Components is a factory for the plug-in components (providers and // provisioners) available for use. Components contextComponentFactory // Schemas is the repository of schemas we will draw from to analyse // the configuration. Schemas *Schemas }
EvalGraphBuilder implements GraphBuilder and constructs a graph suitable for evaluating in-memory values (input variables, local values, output values) in the state without any other side-effects.
This graph is used only in weird cases, such as the "terraform console" CLI command, where we need to evaluate expressions against the state without taking any other actions.
The generated graph will include nodes for providers, resources, etc just to allow indirect dependencies to be resolved, but these nodes will not take any actions themselves since we assume that their parts of the state, if any, are already complete.
Although the providers are never configured, they must still be available in order to obtain schema information used for type checking, etc.

type Evaluator ¶ added in v0.12.0
type Evaluator struct { // Operation defines what type of operation this evaluator is being used // for. Operation walkOperation // Meta is contextual metadata about the current operation. Meta *ContextMeta // Config is the root node in the configuration tree. Config *configs.Config // VariableValues is a map from variable names to their associated values, // within the module indicated by ModulePath.

State *states.SyncState // Changes is the set of proposed changes, embedded in a wrapper that // ensures they can be safely accessed and modified concurrently. Changes *plans.ChangesSync }
Evaluator provides the necessary contextual data for evaluating expressions for a particular walk operation.
type ForcedCBDTransformer ¶ added in v0.12.0
type ForcedCBDTransformer struct { }
ForcedCBDTransformer detects when a particular CBD-able graph node has dependencies with another that has create_before_destroy set that require it to be forced on, and forces it on.
This must be used in the plan graph builder to ensure that create_before_destroy settings are properly propagated before constructing the planned changes. This requires that the plannable resource nodes implement GraphNodeDestroyerCBD.
func (*ForcedCBDTransformer) Transform ¶ added in v0.12.0
func (t *ForcedCBDTransformer) Transform(g *Graph) error
type Graph ¶
type Graph struct { // Graph is the actual DAG. This is embedded so you can call the DAG // methods directly. dag.AcyclicGraph // Path is the path in the module tree that this Graph represents. Path addrs.ModuleInstance }
Graph represents the graph that Terraform uses to represent resources and their dependencies.
func (*Graph) DirectedGraph ¶ added in v0.8.0
func (*Graph) Walk ¶ added in v0.4.0
func (g *Graph) Walk(walker GraphWalker) tfdiags.Diagnostics
Walk walks the graph with the given walker for callbacks. The graph will be walked with full parallelism, so the walker should expect to be called in concurrently.
type GraphBuilder ¶ added in v0.4.0
type GraphBuilder interface { // Build builds the graph for the given module path. It is up to // the interface implementation whether this build should expand // the graph or not. Build(addrs.ModuleInstance) (*Graph, tfdiags.Diagnostics) }
GraphBuilder is an interface that can be implemented and used with Terraform to build the graph that Terraform walks.
func ValidateGraphBuilder ¶ added in v0.9.0
func ValidateGraphBuilder(p *PlanGraphBuilder) GraphBuilder
ValidateGraphBuilder creates the graph for the validate operation.
ValidateGraphBuilder is based on the PlanGraphBuilder. We do this so that we only have to validate what we'd normally plan anyways. The PlanGraphBuilder given will be modified so it shouldn't be used for anything else after calling this function.
type GraphNodeAttachDependencies ¶ added in v0.12.14
type GraphNodeAttachDependencies interface { GraphNodeConfigResource AttachDependencies([]addrs.ConfigResource) }
type GraphNodeAttachProvider ¶ added in v0.7.8
type GraphNodeAttachProvider interface { // ProviderName with no module prefix. Example: "aws". ProviderAddr() addrs.AbsProviderConfig // Sets the configuration AttachProvider(*configs.Provider) }
GraphNodeAttachProvider is an interface that must be implemented by nodes that want provider configurations attached.
type GraphNodeAttachProviderConfigSchema ¶ added in v0.12.0
type GraphNodeAttachProviderConfigSchema interface { GraphNodeProvider AttachProviderConfigSchema(*configschema.Block) }
GraphNodeAttachProviderConfigSchema is an interface implemented by node types that need a provider configuration schema attached.
type GraphNodeAttachProviderMetaConfigs ¶ added in v0.13.0
type GraphNodeAttachProviderMetaConfigs interface { GraphNodeConfigResource // Sets the configuration AttachProviderMetaConfigs(map[addrs.Provider]*configs.ProviderMeta) }
GraphNodeAttachProviderMetaConfigs is an interface that must be implemented by nodes that want provider meta configurations attached.
type GraphNodeAttachProvisionerSchema ¶ added in v0.12.0
type GraphNodeAttachProvisionerSchema interface { ProvisionedBy() []string // SetProvisionerSchema is called during transform for each provisioner // type returned from ProvisionedBy, providing the configuration schema // for each provisioner in turn. The implementer should save these for // later use in evaluating provisioner configuration blocks. AttachProvisionerSchema(name string, schema *configschema.Block) }
GraphNodeAttachProvisionerSchema is an interface implemented by node types that need one or more provisioner schemas attached.
type GraphNodeAttachResourceConfig ¶ added in v0.7.8
type GraphNodeAttachResourceConfig interface { GraphNodeConfigResource // Sets the configuration AttachResourceConfig(*configs.Resource) }
GraphNodeAttachResourceConfig is an interface that must be implemented by nodes that want resource configurations attached.
type GraphNodeAttachResourceSchema ¶ added in v0.12.0
type GraphNodeAttachResourceSchema interface { GraphNodeConfigResource GraphNodeProviderConsumer AttachResourceSchema(schema *configschema.Block, version uint64) }
GraphNodeAttachResourceSchema is an interface implemented by node types that need a resource schema attached.
type GraphNodeAttachResourceState ¶ added in v0.7.8
type GraphNodeAttachResourceState interface { GraphNodeResourceInstance // Sets the state AttachResourceState(*states.Resource) }
GraphNodeAttachResourceState is an interface that can be implemented to request that a ResourceState is attached to the node.
Due to a historical naming inconsistency, the type ResourceState actually represents the state for a particular _instance_, while InstanceState represents the values for that instance during a particular phase (e.g. primary vs. deposed). Consequently, GraphNodeAttachResourceState is supported only for nodes that represent resource instances, even though the name might suggest it is for containing resources.
type GraphNodeCloseProvider ¶ added in v0.6.0
type GraphNodeCloseProvider interface { GraphNodeModulePath CloseProviderAddr() addrs.AbsProviderConfig }
GraphNodeCloseProvider is an interface that nodes that can be a close provider must implement. The CloseProviderName returned is the name of the provider they satisfy.
type GraphNodeCloseProvisioner ¶ added in v0.6.0
type GraphNodeCloseProvisioner interface {
CloseProvisionerName() string
}
GraphNodeCloseProvisioner is an interface that nodes that can be a close provisioner must implement. The CloseProvisionerName returned is the name of the provisioner they satisfy.
type GraphNodeConfigResource ¶ added in v0.4.0
type GraphNodeConfigResource interface {
ResourceAddr() addrs.ConfigResource
}
GraphNodeConfigResource is implemented by any nodes that represent a resource. The type of operation cannot be assumed, only that this node represents the given resource.
type GraphNodeCreator ¶ added in v0.7.8
type GraphNodeCreator interface { // CreateAddr is the address of the resource being created or updated CreateAddr() *addrs.AbsResourceInstance }
GraphNodeCreator must be implemented by nodes that create OR update resources.
type GraphNodeDeposedResourceInstanceObject ¶ added in v0.12.0
type GraphNodeDeposedResourceInstanceObject interface {
DeposedInstanceObjectKey() states.DeposedKey
}
type GraphNodeDeposer ¶ added in v0.12.0
type GraphNodeDeposer interface { // SetPreallocatedDeposedKey will be called during graph construction // if a particular node must use a pre-allocated deposed key if/when it // "deposes" the current object of its associated resource instance. SetPreallocatedDeposedKey(key states.DeposedKey) }
GraphNodeDeposer is an optional interface implemented by graph nodes that might create a single new deposed object for a specific associated resource instance, allowing a caller to optionally pre-allocate a DeposedKey for it.
type GraphNodeDestroyer ¶ added in v0.7.8
type GraphNodeDestroyer interface { dag.Vertex // DestroyAddr is the address of the resource that is being // destroyed by this node. If this returns nil, then this node // is not destroying anything. DestroyAddr() *addrs.AbsResourceInstance }
GraphNodeDestroyer must be implemented by nodes that destroy resources.
type GraphNodeDestroyerCBD ¶ added in v0.7.8
type GraphNodeDestroyerCBD interface { // CreateBeforeDestroy returns true if this node represents a node // that is doing a CBD. CreateBeforeDestroy() bool // ModifyCreateBeforeDestroy is called when the CBD state of a node // is changed dynamically. This can return an error if this isn't // allowed. ModifyCreateBeforeDestroy(bool) error }
GraphNodeDestroyerCBD must be implemented by nodes that might be create-before-destroy destroyers, or might plan a create-before-destroy action.
type GraphNodeDynamicExpandable ¶ added in v0.4.0
type GraphNodeDynamicExpandable interface {
DynamicExpand(EvalContext) (*Graph, error)
}
GraphNodeDynamicExpandable is an interface that nodes can implement to signal that they can be expanded at eval-time (hence dynamic). These nodes are given the eval context and are expected to return a new subgraph.
type GraphNodeExecutable ¶ added in v0.14.0
type GraphNodeExecutable interface {
Execute(EvalContext, walkOperation) tfdiags.Diagnostics
}
GraphNodeExecutable is the interface that graph nodes must implement to enable execution.
type GraphNodeModuleInstance ¶ added in v0.13.0
type GraphNodeModuleInstance interface {
Path() addrs.ModuleInstance
}
GraphNodeModuleInstance says that a node is part of a graph with a different path, and the context should be adjusted accordingly.
type GraphNodeModulePath ¶ added in v0.13.0
GraphNodeModulePath is implemented by all referenceable nodes, to indicate their configuration path in unexpanded modules.
type GraphNodeProvider ¶ added in v0.4.0
type GraphNodeProvider interface { GraphNodeModulePath ProviderAddr() addrs.AbsProviderConfig Name() string }
GraphNodeProvider is an interface that nodes that can be a provider must implement.
ProviderAddr returns the address of the provider configuration this satisfies, which is relative to the path returned by method Path().
Name returns the full name of the provider in the config.
type GraphNodeProviderConsumer ¶ added in v0.4.0
type GraphNodeProviderConsumer interface { GraphNodeModulePath // ProvidedBy returns the address of the provider configuration the node // refers to, if available. The following value types may be returned: // // nil + exact true: the node does not require a provider // * addrs.LocalProviderConfig: the provider was set in the resource config // * addrs.AbsProviderConfig + exact true: the provider configuration was // taken from the instance state. // * addrs.AbsProviderConfig + exact false: no config or state; the returned // value is a default provider configuration address for the resource's // Provider ProvidedBy() (addr addrs.ProviderConfig, exact bool) // Provider() returns the Provider FQN for the node. Provider() (provider addrs.Provider) // Set the resolved provider address for this resource. SetProvider(addrs.AbsProviderConfig) }
GraphNodeProviderConsumer is an interface that nodes that require a provider must implement. ProvidedBy must return the address of the provider to use, which will be resolved to a configuration either in the same module or in an ancestor module, with the resulting absolute address passed to SetProvider.
type GraphNodeProvisioner ¶ added in v0.4.0
type GraphNodeProvisioner interface {
ProvisionerName() string
}
GraphNodeProvisioner is an interface that nodes that can be a provisioner must implement. The ProvisionerName returned is the name of the provisioner they satisfy.
type GraphNodeProvisionerConsumer ¶ added in v0.4.0
type GraphNodeProvisionerConsumer interface {
ProvisionedBy() []string
}
GraphNodeProvisionerConsumer is an interface that nodes that require a provisioner must implement. ProvisionedBy must return the names of the provisioners to use.
type GraphNodeReferenceOutside ¶ added in v0.12.0
type GraphNodeReferenceOutside interface { // ReferenceOutside returns a path in which any references from this node // are resolved. ReferenceOutside() (selfPath, referencePath addrs.Module) }
GraphNodeReferenceOutside is an interface that can optionally be implemented. A node that implements it can specify that its own referenceable addresses and/or the addresses it references are in a different module than the node itself.
Any referenceable addresses returned by ReferenceableAddrs are interpreted relative to the returned selfPath.
Any references returned by References are interpreted relative to the returned referencePath.
It is valid but not required for either of these paths to match what is returned by method Path, though if both match the main Path then there is no reason to implement this method.
The primary use-case for this is the nodes representing module input variables, since their expressions are resolved in terms of their calling module, but they are still referenced from their own module.
type GraphNodeReferenceable ¶ added in v0.7.8
type GraphNodeReferenceable interface { GraphNodeModulePath // ReferenceableAddrs returns a list of addresses through which this can be // referenced. ReferenceableAddrs() []addrs.Referenceable }
GraphNodeReferenceable must be implemented by any node that represents a Terraform thing that can be referenced (resource, module, etc.).
Even if the thing has no name, this should return an empty list. By implementing this and returning a non-nil result, you say that this CAN be referenced and other methods of referencing may still be possible (such as by path!)
type GraphNodeReferencer ¶ added in v0.7.8
type GraphNodeReferencer interface { GraphNodeModulePath // References returns a list of references made by this node, which // include both a referenced address and source location information for // the reference. References() []*addrs.Reference }
GraphNodeReferencer must be implemented by nodes that reference other Terraform items and therefore depend on them.
type GraphNodeResourceInstance ¶ added in v0.12.0
type GraphNodeResourceInstance interface { ResourceInstanceAddr() addrs.AbsResourceInstance // StateDependencies returns any inter-resource dependencies that are // stored in the state. StateDependencies() []addrs.ConfigResource }
GraphNodeResourceInstance is implemented by any nodes that represent a resource instance. A single resource may have multiple instances if, for example, the "count" or "for_each" argument is used for it in configuration.
type GraphNodeTargetable ¶ added in v0.4.0
type GraphNodeTargetable interface {
SetTargets([]addrs.Targetable)
}
GraphNodeTargetable is an interface for graph nodes to implement when they need to be told about incoming targets. This is useful for nodes that need to respect targets as they dynamically expand. Note that the list of targets provided will contain every target provided, and each implementing graph node must filter this list to targets considered relevant.
type GraphTransformer ¶ added in v0.4.0
GraphTransformer is the interface that transformers implement. This interface is only for transforms that need entire graph visibility.
func GraphTransformMulti ¶ added in v0.7.8
func GraphTransformMulti(ts ...GraphTransformer) GraphTransformer
GraphTransformMulti combines multiple graph transformers into a single GraphTransformer that runs all the individual graph transformers.
func TransformProviders ¶ added in v0.11.0
func TransformProviders(providers []string, concrete ConcreteProviderNodeFunc, config *configs.Config) GraphTransformer
type GraphType ¶ added in v0.8.0
type GraphType byte
GraphType is an enum of the type of graph to create with a Context. The values of the constants may change so they shouldn't be depended on; always use the constant name.
type GraphVertexTransformer ¶ added in v0.4.0
GraphVertexTransformer is an interface that transforms a single Vertex within with graph. This is a specialization of GraphTransformer that makes it easy to do vertex replacement.
The GraphTransformer that runs through the GraphVertexTransformers is VertexTransformer.
type GraphWalker ¶ added in v0.4.0
type GraphWalker interface { EvalContext() EvalContext EnterPath(addrs.ModuleInstance) EvalContext ExitPath(addrs.ModuleInstance) Execute(EvalContext, GraphNodeExecutable) tfdiags.Diagnostics }
GraphWalker is an interface that can be implemented that when used with Graph.Walk will invoke the given callbacks under certain events.
type Hook ¶
type Hook interface { // PreApply and PostApply are called before and after an action for a // single instance is applied. The error argument in PostApply is the // error, if any, that was returned from the provider Apply call itself. PreApply(addr addrs.AbsResourceInstance, gen states.Generation, action plans.Action, priorState, plannedNewState cty.Value) (HookAction, error) PostApply(addr addrs.AbsResourceInstance, gen states.Generation, newState cty.Value, err error) (HookAction, error) // PreDiff and PostDiff are called before and after a provider is given // the opportunity to customize the proposed new state to produce the // planned new state. PreDiff(addr addrs.AbsResourceInstance, gen states.Generation, priorState, proposedNewState cty.Value) (HookAction, error) PostDiff(addr addrs.AbsResourceInstance, gen states.Generation, action plans.Action, priorState, plannedNewState cty.Value) (HookAction, error) // The provisioning hooks signal both the overall start end end of // provisioning for a particular instance and of each of the individual // configured provisioners for each instance. The sequence of these // for a given instance might look something like this: // // PreProvisionInstance(aws_instance.foo[1], ...) // PreProvisionInstanceStep(aws_instance.foo[1], "file") // PostProvisionInstanceStep(aws_instance.foo[1], "file", nil) // PreProvisionInstanceStep(aws_instance.foo[1], "remote-exec") // ProvisionOutput(aws_instance.foo[1], "remote-exec", "Installing foo...") // ProvisionOutput(aws_instance.foo[1], "remote-exec", "Configuring bar...") // PostProvisionInstanceStep(aws_instance.foo[1], "remote-exec", nil) // PostProvisionInstance(aws_instance.foo[1], ...) // // ProvisionOutput is called with output sent back by the provisioners. // This will be called multiple times as output comes in, with each call // representing one line of output. It cannot control whether the // provisioner continues running. PreProvisionInstance(addr addrs.AbsResourceInstance, state cty.Value) (HookAction, error) PostProvisionInstance(addr addrs.AbsResourceInstance, state cty.Value) (HookAction, error) PreProvisionInstanceStep(addr addrs.AbsResourceInstance, typeName string) (HookAction, error) PostProvisionInstanceStep(addr addrs.AbsResourceInstance, typeName string, err error) (HookAction, error) ProvisionOutput(addr addrs.AbsResourceInstance, typeName string, line string) // PreRefresh and PostRefresh are called before and after a single // resource state is refreshed, respectively. PreRefresh(addr addrs.AbsResourceInstance, gen states.Generation, priorState cty.Value) (HookAction, error) PostRefresh(addr addrs.AbsResourceInstance, gen states.Generation, priorState cty.Value, newState cty.Value) (HookAction, error) // PreImportState and PostImportState are called before and after // (respectively) each state import operation for a given resource address. PreImportState(addr addrs.AbsResourceInstance, importID string) (HookAction, error) PostImportState(addr addrs.AbsResourceInstance, imported []providers.ImportedResource) (HookAction, error) // PostStateUpdate is called each time the state is updated. It receives // a deep copy of the state, which it may therefore access freely without // any need for locks to protect from concurrent writes from the caller. PostStateUpdate(new *states.State) (HookAction, error) }
Hook is the interface that must be implemented to hook into various parts of Terraform, allowing you to inspect or change behavior at runtime.
There are MANY hook points into Terraform. If you only want to implement some hook points, but not all (which is the likely case), then embed the NilHook into your struct, which implements all of the interface but does nothing. Then, override only the functions you want to implement.
type HookAction ¶
type HookAction byte
HookAction is an enum of actions that can be taken as a result of a hook callback. This allows you to modify the behavior of Terraform at runtime.
const ( // HookActionContinue continues with processing as usual. HookActionContinue HookAction = iota // HookActionHalt halts immediately: no more hooks are processed // and the action that Terraform was about to take is cancelled. HookActionHalt )
type ImportGraphBuilder ¶ added in v0.7.0
type ImportGraphBuilder struct { // ImportTargets are the list of resources to import. ImportTargets []*ImportTarget // Module is a configuration to build the graph from. See ImportOpts.Config. Config *configs.Config // Components is the factory for our available plugin components. Components contextComponentFactory // Schemas is the repository of schemas we will draw from to analyse // the configuration. Schemas *Schemas }
ImportGraphBuilder implements GraphBuilder and is responsible for building a graph for importing resources into Terraform. This is a much, much simpler graph than a normal configuration graph.
func (*ImportGraphBuilder) Build ¶ added in v0.7.0
func (b *ImportGraphBuilder) Build(path addrs.ModuleInstance) (*Graph, tfdiags.Diagnostics)
Build builds the graph according to the steps returned by Steps.
func (*ImportGraphBuilder) Steps ¶ added in v0.7.0

This is resource-specific. ID string // ProviderAddr is the address of the provider that should handle the import. ProviderAddr addrs.AbsProviderConfig }
ImportTarget is a single resource to import.
type InputMode ¶ added in v0.3.0
type InputMode byte
InputMode defines what sort of input will be asked for when Input is called on Context.
const ( // InputModeProvider asks for provider variables InputModeProvider InputMode = 1 << iota // InputModeStd is the standard operating mode and asks for both variables // and providers. InputModeStd = InputModeProvider )
type InputOpts ¶ added in v0.3.0
type InputOpts struct { // Id is a unique ID for the question being asked that might be // used for logging or to look up a prior answered question. Id string // Query is a human-friendly question for inputting this value. Query string // Description is a description about what this option is. Be wary // that this will probably be in a terminal so split lines as you see // necessary. Description string // Default will be the value returned if no data is entered. Default string // Secret should be true if we are asking for sensitive input. // If attached to a TTY, Terraform will disable echo. Secret bool }
InputOpts are options for asking for input.
type InputValue ¶ added in v0.12.0
type InputValue struct { Value cty.Value SourceType ValueSourceType // SourceRange provides source location information for values whose // SourceType is either ValueFromConfig or ValueFromFile. It is not // populated for other source types, and so should not be used. SourceRange tfdiags.SourceRange }

func DefaultVariableValues(configs map[string]*configs.Variable) InputValues
DefaultVariableValues returns an InputValues map representing the default values specified for variables in the given configuration map.
func InputValuesFromCaller ¶ added in v0.12.0
func InputValuesFromCaller(vals map[string]cty.Value) InputValues
InputValuesFromCaller turns the given map of naked values into an InputValues that attributes each value to "a caller", using the source type ValueFromCaller. This is primarily useful for testing purposes.
This should not be used as a general way to convert map[string]cty.Value into InputValues, since in most real cases we want to set a suitable other SourceType and possibly SourceRange value.
func (InputValues) HasValues ¶ added in v0.12.0
func (vv InputValues) HasValues(vals map[string]cty.Value) bool
HasValues returns true if the reciever has the same values as in the given map, disregarding the source types and source ranges.
Values are compared using the cty "RawEquals" method, which means that unknown values can be considered equal to one another if they are of the same type.
func (InputValues) Identical ¶ added in v0.12.0
func (vv InputValues) Identical(other InputValues) bool
Identical returns true if the given InputValues has the same values, source types, and source ranges as the receiver.
Values are compared using the cty "RawEquals" method, which means that unknown values can be considered equal to one another if they are of the same type.
This method is primarily for testing. For most practical purposes, it's better to use SameValues or HasValues.
func (InputValues) JustValues ¶ added in v0.12.0
func (vv InputValues) JustValues() map[string]cty.Value
JustValues returns a map that just includes the values, discarding the source information.
func (InputValues) Override ¶ added in v0.12.0
func (vv InputValues) Override(others ...InputValues) InputValues
Override merges the given value maps with the receiver, overriding any conflicting keys so that the latest definition wins.
func (InputValues) SameValues ¶ added in v0.12.0
func (vv InputValues) SameValues(other InputValues) bool
SameValues returns true if the given InputValues has the same values as the receiever, disregarding the source types and source ranges.
Values are compared using the cty "RawEquals" method, which means that unknown values can be considered equal to one another if they are of the same type.
type InstanceKeyEvalData ¶ added in v0.12.0
type InstanceKeyEvalData = instances.RepetitionData
InstanceKeyEvalData is the old name for instances.RepetitionData, aliased here for compatibility. In new code, use instances.RepetitionData instead.
func EvalDataForInstanceKey ¶ added in v0.12.0
func EvalDataForInstanceKey(key addrs.InstanceKey, forEachMap map[string]cty.Value) InstanceKeyEvalData
EvalDataForInstanceKey constructs a suitable InstanceKeyEvalData for evaluating in a context that has the given instance key.
The forEachMap argument can be nil when preparing for evaluation in a context where each.value is prohibited, such as a destroy-time provisioner. In that case, the returned EachValue will always be cty.NilVal.
type LocalTransformer ¶ added in v0.10.3
LocalTransformer is a GraphTransformer that adds all the local values from the configuration to the graph.
func (*LocalTransformer) Transform ¶ added in v0.10.3
func (t *LocalTransformer) Transform(g *Graph) error
type MissingProviderTransformer ¶ added in v0.4.0
type MissingProviderTransformer struct { // Providers is the list of providers we support. Providers []string // MissingProviderTransformer needs the config to rule out _implied_ default providers Config *configs.Config // Concrete, if set, overrides how the providers are made. Concrete ConcreteProviderNodeFunc }
MissingProviderTransformer is a GraphTransformer that adds to the graph a node for each default provider configuration that is referenced by another node but not already present in the graph.
These "default" nodes are always added to the root module, regardless of where they are requested. This is important because our inheritance resolution behavior in ProviderTransformer will then treat these as a last-ditch fallback after walking up the tree, rather than preferring them as it would if they were placed in the same module as the requester.
This transformer may create extra nodes that are not needed in practice, due to overriding provider configurations in child modules. PruneProviderTransformer can then remove these once ProviderTransformer has resolved all of the inheritence, etc.
func (*MissingProviderTransformer) Transform ¶ added in v0.4.0
func (t *MissingProviderTransformer) Transform(g *Graph) error
type MissingProvisionerTransformer ¶ added in v0.4.0

type OrphanOutputTransformer ¶ added in v0.7.8
type OrphanOutputTransformer struct { Config *configs.Config // Root of config tree State *states.State // State is the root state }
OrphanOutputTransformer finds the outputs that aren't present in the given config that are in the state and adds them to the graph for deletion.
func (*OrphanOutputTransformer) Transform ¶ added in v0.7.8
func (t *OrphanOutputTransformer) Transform(g *Graph) error
type OrphanResourceInstanceCountTransformer ¶ added in v0.13.0
type OrphanResourceInstanceCountTransformer struct { Concrete ConcreteResourceInstanceNodeFunc Addr addrs.AbsResource // Addr of the resource to look for orphans InstanceAddrs []addrs.AbsResourceInstance // Addresses that currently exist in config State *states.State // Full global state }
OrphanResourceInstanceCountTransformer is a GraphTransformer that adds orphans for an expanded count to the graph. The determination of this depends on the count argument given.
Orphans are found by comparing the count to what is found in the state. This transform assumes that if an element in the state is within the count bounds given, that it is not an orphan.
func (*OrphanResourceInstanceCountTransformer) Transform ¶ added in v0.13.0
func (t *OrphanResourceInstanceCountTransformer) Transform(g *Graph) error
type OrphanResourceInstanceTransformer ¶ added in v0.12.0

State *states.State // Config is the root node in the configuration tree. We'll look up // the appropriate note in this tree using the path in each node. Config *configs.Config }
OrphanResourceInstanceTransformer is a GraphTransformer that adds orphaned resource instances to the graph. An "orphan" is an instance that is present in the state but belongs to a resource that is no longer present in the configuration.
This is not the transformer that deals with "count orphans" (instances that are no longer covered by a resource's "count" or "for_each" setting); that's handled instead by OrphanResourceCountTransformer.
func (*OrphanResourceInstanceTransformer) Transform ¶ added in v0.12.0
func (t *OrphanResourceInstanceTransformer) Transform(g *Graph) error
type OutputTransformer ¶ added in v0.7.8
type OutputTransformer struct { Config *configs.Config Changes *plans.Changes // if this is a planed destroy, root outputs are still in the configuration // so we need to record that we wish to remove them Destroy bool }
OutputTransformer is a GraphTransformer that adds all the outputs in the configuration to the graph.
This is done for the apply graph builder even if dependent nodes aren't changing since there is no downside: the state will be available even if the dependent items aren't changing.
func (*OutputTransformer) Transform ¶ added in v0.7.8
func (t *OutputTransformer) Transform(g *Graph) error
type ParentProviderTransformer ¶ added in v0.7.8
type ParentProviderTransformer struct{}

func (*ParentProviderTransformer) Transform ¶ added in v0.7.8
func (t *ParentProviderTransformer) Transform(g *Graph) error
type PlanGraphBuilder ¶ added in v0.7.10
type PlanGraphBuilder struct { // Config is the configuration tree to build a plan from. Config *configs.Config // State is the current state State *states.State // Components is a factory for the plug-in components (providers and // provisioners) available for use. Components contextComponentFactory // Schemas is the repository of schemas we will draw from to analyse // the configuration. Schemas *Schemas // Targets are resources to target Targets []addrs.Targetable // Validate will do structural validation of the graph. Validate bool // CustomConcrete can be set to customize the node types created // for various parts of the plan. This is useful in order to customize // the plan behavior. CustomConcrete bool ConcreteProvider ConcreteProviderNodeFunc ConcreteResource ConcreteResourceNodeFunc ConcreteResourceOrphan ConcreteResourceInstanceNodeFunc ConcreteModule ConcreteModuleNodeFunc // contains filtered or unexported fields }
PlanGraphBuilder implements GraphBuilder and is responsible for building a graph for planning (creating a Terraform Diff).
The primary difference between this graph and others:
Based on the config since it represents the target state
Ignores lifecycle options since no lifecycle events occur here. This simplifies the graph significantly since complex transforms such as create-before-destroy can be completely ignored.
func (*PlanGraphBuilder) Build ¶ added in v0.7.10
func (b *PlanGraphBuilder) Build(path addrs.ModuleInstance) (*Graph, tfdiags.Diagnostics)
See GraphBuilder

func (*RootVariableTransformer) Transform ¶ added in v0.7.8
func (t *RootVariableTransformer) Transform(g *Graph) error
type Schemas ¶ added in v0.10.8
type Schemas struct { Providers map[addrs.Provider]*ProviderSchema Provisioners map[string]*configschema.Block }
Schemas is a container for various kinds of schema that Terraform needs during processing.
func LoadSchemas ¶ added in v0.12.0
func LoadSchemas(config *configs.Config, state *states.State, components contextComponentFactory) (*Schemas, error)
LoadSchemas searches the given configuration, state and plan (any of which may be nil) for constructs that have an associated schema, requests the necessary schemas from the given component factory (which must _not_ be nil), and returns a single object representing all of the necessary schemas.
If an error is returned, it may be a wrapped tfdiags.Diagnostics describing errors across multiple separate objects. Errors here will usually indicate either misbehavior on the part of one of the providers or of the provider protocol itself. When returned with errors, the returned schemas object is still valid but may be incomplete.
func (*Schemas) ProviderConfig ¶ added in v0.12.0
func (ss *Schemas) ProviderConfig(provider addrs.Provider) *configschema.Block
ProviderConfig returns the schema for the provider configuration of the given provider type, or nil if no such schema is available.
func (*Schemas) ProviderSchema ¶ added in v0.12.0
func (ss *Schemas) ProviderSchema(provider addrs.Provider) *ProviderSchema
ProviderSchema returns the entire ProviderSchema object that was produced by the plugin for the given provider, or nil if no such schema is available.
It's usually better to go use the more precise methods offered by type Schemas to handle this detail automatically.
func (*Schemas) ProvisionerConfig ¶ added in v0.12.0
func (ss *Schemas) ProvisionerConfig(name string) *configschema.Block
ProvisionerConfig returns the schema for the configuration of a given provisioner, or nil of no such schema is available.
func (*Schemas) ResourceTypeConfig ¶ added in v0.12.0

ResourceTypeConfig returns the schema for the configuration of a given resource type belonging to a given provider type, or nil of no such schema is available.
In many cases the provider type is inferrable from the resource type name, but this is not always true because users can override the provider for a resource using the "provider" meta-argument. Therefore it's important to always pass the correct provider name, even though it many cases it feels redundant.
