Constants

View Source 
const (
	// The constants below are the names of the plugins that can be dispensed
	// from the plugin server.
	ProviderPluginName    = "provider"
	ProvisionerPluginName = "provisioner"

	// DefaultProtocolVersion is the protocol version assumed for legacy clients that don't specify
	// a particular version during their handshake. This is the version used when Terraform 0.10
	// and 0.11 launch plugins that were built with support for both versions 4 and 5, and must
	// stay unchanged at 4 until we intentionally build plugins that are not compatible with 0.10 and
	// 0.11.
	DefaultProtocolVersion = 4
)

var Handshake = plugin.HandshakeConfig{

	ProtocolVersion: DefaultProtocolVersion,

	MagicCookieKey:   "TF_PLUGIN_MAGIC_COOKIE",
	MagicCookieValue: "d602bf8f470bc67ca7faa0386276bbdd4330efaf76d1a219cb4d6991ca9872b2",
}

Handshake is the HandshakeConfig used to configure clients and servers.

var VersionedPlugins = map[int]plugin.PluginSet{
	5: {
		"provider": &GRPCProviderPlugin{},
	},
}

VersionedPlugins includes both protocol 5 and 6 because this is the function called in providerFactory (command/meta_providers.go) to set up the initial plugin client config.

Functions

func Serve 

func Serve(opts *ServeOpts)

Serve serves a plugin. This function never returns and should be the final function called in the main function of the plugin.

Types

type GRPCProvider 

type GRPCProvider struct {
	// PluginClient provides a reference to the plugin.Client which controls the plugin process.
	// This allows the GRPCProvider a way to shutdown the plugin process.
	PluginClient *plugin.Client

	// TestServer contains a grpc.Server to close when the GRPCProvider is being
	// used in an end to end test of a provider.
	TestServer *grpc.Server
	// contains filtered or unexported fields
}

GRPCProvider handles the client, or core side of the plugin rpc connection. The GRPCProvider methods are mostly a translation layer between the terraform providers types and the grpc proto types, directly converting between the two.

func (*GRPCProvider) ApplyResourceChange 

func (p *GRPCProvider) ApplyResourceChange(r providers.ApplyResourceChangeRequest) (resp providers.ApplyResourceChangeResponse)

func (*GRPCProvider) Close 

func (p *GRPCProvider) Close() error

closing the grpc connection is final, and terraform will call it at the end of every phase.

func (*GRPCProvider) ConfigureProvider 

func (p *GRPCProvider) ConfigureProvider(r providers.ConfigureProviderRequest) (resp providers.ConfigureProviderResponse)

func (*GRPCProvider) GetProviderSchema 

func (p *GRPCProvider) GetProviderSchema() (resp providers.GetProviderSchemaResponse)

func (*GRPCProvider) ImportResourceState 

func (p *GRPCProvider) ImportResourceState(r providers.ImportResourceStateRequest) (resp providers.ImportResourceStateResponse)

func (*GRPCProvider) PlanResourceChange 

func (p *GRPCProvider) PlanResourceChange(r providers.PlanResourceChangeRequest) (resp providers.PlanResourceChangeResponse)

func (*GRPCProvider) ReadDataSource 

func (p *GRPCProvider) ReadDataSource(r providers.ReadDataSourceRequest) (resp providers.ReadDataSourceResponse)

func (*GRPCProvider) ReadResource 

func (p *GRPCProvider) ReadResource(r providers.ReadResourceRequest) (resp providers.ReadResourceResponse)

func (*GRPCProvider) Stop 

func (p *GRPCProvider) Stop() error

func (*GRPCProvider) UpgradeResourceState 

func (p *GRPCProvider) UpgradeResourceState(r providers.UpgradeResourceStateRequest) (resp providers.UpgradeResourceStateResponse)

func (*GRPCProvider) ValidateDataResourceConfig 

func (p *GRPCProvider) ValidateDataResourceConfig(r providers.ValidateDataResourceConfigRequest) (resp providers.ValidateDataResourceConfigResponse)

func (*GRPCProvider) ValidateProviderConfig 

func (p *GRPCProvider) ValidateProviderConfig(r providers.ValidateProviderConfigRequest) (resp providers.ValidateProviderConfigResponse)

func (*GRPCProvider) ValidateResourceConfig 

func (p *GRPCProvider) ValidateResourceConfig(r providers.ValidateResourceConfigRequest) (resp providers.ValidateResourceConfigResponse)

type GRPCProviderFunc 

type GRPCProviderFunc func() proto.ProviderServer

type GRPCProviderPlugin 

type GRPCProviderPlugin struct {
	plugin.Plugin
	GRPCProvider func() proto.ProviderServer
}

GRPCProviderPlugin implements plugin.GRPCPlugin for the go-plugin package.

func (*GRPCProviderPlugin) GRPCClient 

func (p *GRPCProviderPlugin) GRPCClient(ctx context.Context, broker *plugin.GRPCBroker, c *grpc.ClientConn) (interface{}, error)

func (*GRPCProviderPlugin) GRPCServer 

func (p *GRPCProviderPlugin) GRPCServer(broker *plugin.GRPCBroker, s *grpc.Server) error

type GRPCProvisionerFunc 

type GRPCProvisionerFunc func() proto.ProvisionerServer

type ServeOpts 

type ServeOpts struct {
	// Wrapped versions of the above plugins will automatically shimmed and
	// added to the GRPC functions when possible.
	GRPCProviderFunc    GRPCProviderFunc
	GRPCProvisionerFunc GRPCProvisionerFunc
}

ServeOpts are the configurations to serve a plugin.
