	// 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

Functions

func Client 

func Client(m discovery.PluginMeta) *plugin.Client

Client returns a plugin client for the plugin described by the given metadata.

func ClientConfig 

func ClientConfig(m discovery.PluginMeta) *plugin.ClientConfig

ClientConfig returns a configuration object that can be used to instantiate a client for the plugin described by the given metadata.

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 provioders types and the grpc proto types, directly converting between the two.

func (p *GRPCProvider) Close() error

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