Types

type ErrInadequateCapability

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

ErrInadequateCapability indicates that the plugin did not have the requested capability.

func (ErrInadequateCapability) Error

type Plugin

type Plugin struct {
	PluginObj types.Plugin `json:"plugin"` // todo: embed struct

	PropagatedMount string // TODO: make private
	Rootfs          string // TODO: make private

	Config   digest.Digest
	Blobsums []digest.Digest

	SwarmServiceID string
	// contains filtered or unexported fields
}
