Types

type Backend

type Backend interface {
	Disable(name string, config *backend.PluginDisableConfig) error
	Enable(name string, config *backend.PluginEnableConfig) error
	Remove(name string, config *backend.PluginRmConfig) error
	Pull(ctx context.Context, ref reference.Named, name string, metaHeaders http.Header, authConfig *registry.AuthConfig, privileges types.PluginPrivileges, outStream io.Writer, opts ...plugin.CreateOpt) error
	Upgrade(ctx context.Context, ref reference.Named, name string, metaHeaders http.Header, authConfig *registry.AuthConfig, privileges types.PluginPrivileges, outStream io.Writer) error
	Get(name string) (*v2.Plugin, error)
	SubscribeEvents(buffer int, events ...plugin.Event) (eventCh <-chan interface{}, cancel func())
}

Backend is the interface for interacting with the plugin manager Controller actions are passed to the configured backend to do the real work.

type Controller

type Controller struct {
	// contains filtered or unexported fields
}

Controller is the controller for the plugin backend. Plugins are managed as a singleton object with a desired state (different from containers). With the plugin controller instead of having a strict create->start->stop->remove task lifecycle like containers, we manage the desired state of the plugin and let the plugin manager do what it already does and monitor the plugin. We'll also end up with many tasks all pointing to the same plugin ID.

TODO(@cpuguy83): registry auth is intentionally not supported until we work out the right way to pass registry credentials via secrets.
