Functions

func NewBackend 

func NewBackend(ctx context.Context, pluginName string, pluginType consts.PluginType, sys pluginutil.LookRunnerUtil, conf *logical.BackendConfig, isMetadataMode bool) (logical.Backend, error)

NewBackend will return an instance of an RPC-based client implementation of the backend for external plugins, or a concrete implementation of the backend if it is a builtin backend. The backend is returned as a logical.Backend interface. The isMetadataMode param determines whether the plugin should run in metadata mode.

func NewPluginClient added in v1.0.0 

func NewPluginClient(ctx context.Context, sys pluginutil.RunnerUtil, pluginRunner *pluginutil.PluginRunner, logger log.Logger, isMetadataMode bool) (logical.Backend, error)

func Serve 

func Serve(opts *ServeOpts) error

Serve is a helper function used to serve a backend plugin. This should be ran on the plugin's main process.

Types

type BackendPluginClient 

type BackendPluginClient struct {
	sync.Mutex

	logical.Backend
	// contains filtered or unexported fields
}

BackendPluginClient is a wrapper around backendPluginClient that also contains its plugin.Client instance. It's primarily used to cleanly kill the client on Cleanup()

func (*BackendPluginClient) Cleanup 

func (b *BackendPluginClient) Cleanup(ctx context.Context)

Cleanup calls the RPC client's Cleanup() func and also calls the go-plugin's client Kill() func

type GRPCBackendPlugin added in v0.11.4 

type GRPCBackendPlugin struct {
	Factory      logical.Factory
	MetadataMode bool
	Logger       log.Logger

	// Embeding this will disable the netRPC protocol
	plugin.NetRPCUnsupportedPlugin
}

GRPCBackendPlugin is the plugin.Plugin implementation that only supports GRPC transport

func (*GRPCBackendPlugin) GRPCClient added in v0.11.4 

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