	GetRequiredPlugins(info ProgInfo) ([]workspace.PluginInfo, error)
	// Run executes a program in the language runtime for planning or deployment purposes.  If
	// info.DryRun is true, the code must not assume that side-effects or final values resulting

	// deployment is occurring and it may safely depend on these.
	//
	// Returns a triple of "error message", "bail", or real "error".  If "bail", the caller should

}

Provider presents a simple interface for orchestrating resource create, read, update, and delete operations. Each provider understands how to handle all of the resource types within a single package.

This interface hides some of the messiness of the underlying machinery, since providers are behind an RPC boundary.

It is important to note that provider operations are not transactional. (Some providers might decide to offer transactional semantics, but such a provider is a rare treat.) As a result, failures in the operations below can range from benign to catastrophic (possibly leaving behind a corrupt resource). It is up to the provider to make a best effort to ensure catastrophes do not occur. The errors returned from mutating operations indicate both the underlying error condition in addition to a bit indicating whether the operation was successfully rolled back.

func NewProvider 

func NewProvider(host Host, ctx *Context, pkg tokens.Package, version *semver.Version,
	options map[string]interface{}, disableProviderPreview bool) (Provider, error)

NewProvider attempts to bind to a given package's resource plugin and then creates a gRPC connection to it. If the plugin could not be found, or an error occurs while creating the child process, an error is returned.

func NewProviderWithClient added in v2.16.2 

func NewProviderWithClient(ctx *Context, pkg tokens.Package, client pulumirpc.ResourceProviderClient,
	disableProviderPreview bool) Provider

type PulumiPluginJSON added in v2.15.1 

type PulumiPluginJSON struct {
	// Indicates whether the package has an associated resource plugin. Set to false to indicate no plugin.
	Resource bool `json:"resource"`
	// Optional plugin name. If not set, the plugin name is derived from the package name.
	Name string `json:"name,omitempty"`
	// Optional plugin version. If not set, the version is derived from the package version (if possible).
	Version string `json:"version,omitempty"`
	// Optional plugin server. If not set, the default server is used when installing the plugin.
	Server string `json:"server,omitempty"`
}

PulumiPluginJSON represents additional information about a package's associated Pulumi plugin. For Python, the content is inside a pulumiplugin.json file inside the package. For Node.js, the content is within the package.json file, under the "pulumi" node. This is not currently used for .NET or Go, but we could consider adopting it for those languages.

func LoadPulumiPluginJSON added in v2.15.1 

func LoadPulumiPluginJSON(path string) (*PulumiPluginJSON, error)

func (*PulumiPluginJSON) JSON added in v2.15.1 

func (plugin *PulumiPluginJSON) JSON() ([]byte, error)

type ReadResult 

type ReadResult struct {
	// This is the ID for the resource. This ID will always be populated and will ensure we get the most up-to-date
	// resource ID.
	ID resource.ID
	// Inputs contains the new inputs for the resource, if any. If this field is nil, the provider does not support
	// returning inputs from a call to Read and the old inputs (if any) should be preserved.
	Inputs resource.PropertyMap
	// Outputs contains the new outputs/state for the resource, if any. If this field is nil, the resource does not
	// exist.
	Outputs resource.PropertyMap
}

ReadResult is the result of a call to Read.

type RunInfo 

type RunInfo struct {
	MonitorAddress string                // the RPC address to the host resource monitor.
	Project        string                // the project name housing the program being run.
	Stack          string                // the stack name being evaluated.
	Pwd            string                // the program's working directory.
	Program        string                // the path to the program to execute.
	Args           []string              // any arguments to pass to the program.
	Config         map[config.Key]string // the configuration variables to apply before running.
	DryRun         bool                  // true if we are performing a dry-run (preview).
	QueryMode      bool                  // true if we're only doing a query.
	Parallel       int                   // the degree of parallelism for resource operations (<=1 for serial).
}

RunInfo contains all of the information required to perform a plan or deployment operation.
