Overview ¶
Package daemon exposes the functions that occur on the host server that the Docker daemon is running.
In implementing the various functions of the daemon, there is often a method-specific struct for configuring the runtime behavior.

A negative (-1) timeout means "indefinitely", which means that containers are not forcibly killed, and the daemon shuts down after all containers exit.
func (*Daemon) StoreHosts ¶
StoreHosts stores the addresses the daemon is listening on
func (*Daemon) Subnets ¶
Subnets return the IPv4 and IPv6 subnets of networks that are manager by Docker.
func (*Daemon) SubscribeToEvents ¶
func (daemon *Daemon) SubscribeToEvents(since, until time.Time, filter filters.Args) ([]events.Message, chan interface{})
SubscribeToEvents returns the currently record of events, a channel to stream new events from, and a function to cancel the stream of events.
func (*Daemon) SystemDiskUsage ¶
SystemDiskUsage returns information about the daemon data disk usage
func (*Daemon) SystemInfo ¶
SystemInfo returns information about the host server the daemon is running on.
func (*Daemon) SystemVersion ¶
SystemVersion returns version information about the daemon.
func (*Daemon) UnsubscribeFromEvents ¶
func (daemon *Daemon) UnsubscribeFromEvents(listener chan interface{})
UnsubscribeFromEvents stops the event subscription for a client by closing the channel where the daemon sends events to.
func (*Daemon) UpdateAttachment ¶
func (daemon *Daemon) UpdateAttachment(networkName, networkID, containerID string, config *network.NetworkingConfig) error
UpdateAttachment notifies the attacher about the attachment config.
func (*Daemon) UpdateContainerServiceConfig ¶
func (daemon *Daemon) UpdateContainerServiceConfig(containerName string, serviceConfig *clustertypes.ServiceConfig) error
UpdateContainerServiceConfig updates a service configuration.
func (*Daemon) VolumesService ¶
func (daemon *Daemon) VolumesService() *service.VolumesService
VolumesService is used to perform volume operations
type NetworkManager ¶
type NetworkManager interface { GetNetwork(input string) (apitypes.NetworkResource, error) GetNetworks(filters.Args) ([]apitypes.NetworkResource, error) RemoveNetwork(input string) error }
NetworkManager provides methods to manage networks
type PredefinedNetworkError ¶
type PredefinedNetworkError string
PredefinedNetworkError is returned when user tries to create predefined network that already exists.
func (PredefinedNetworkError) Error ¶
func (pnr PredefinedNetworkError) Error() string
func (PredefinedNetworkError) Forbidden ¶
