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.

Index

Constants

View Source 
const (
	// NetworkByID represents a constant to find a network by its ID
	NetworkByID = iota + 1
	// NetworkByName represents a constant to find a network by its Name
	NetworkByName
)

Variables

View Source 
var ErrExtractPointNotDirectory = errors.New("extraction point is not a directory")

ErrExtractPointNotDirectory is used to convey that the operation to extract a tar archive to a directory in a container has failed because the specified path does not refer to a directory.

View Source 
var (
	// ErrRootFSReadOnly is returned when a container
	// rootfs is marked readonly.
	ErrRootFSReadOnly = errors.New("container rootfs is marked read-only")
)
View Source 
var (
	// ErrVolumeReadonly is used to signal an error when trying to copy data into
	// a volume mount that is not writable.
	ErrVolumeReadonly = errors.New("mounted volume is marked read-only")
)

Functions

func (*Daemon) ImageDelete added in v1.2.0 

func (daemon *Daemon) ImageDelete(imageRef string, force, prune bool) ([]types.ImageDelete, error)

ImageDelete deletes the image referenced by the given imageRef from this daemon. The given imageRef can be an image ID, ID prefix, or a repository reference (with an optional tag or digest, defaulting to the tag name "latest"). There is differing behavior depending on whether the given imageRef is a repository reference or not.

If the given imageRef is a repository reference then that repository reference will be removed. However, if there exists any containers which were created using the same image reference then the repository reference cannot be removed unless either there are other repository references to the same image or force is true. Following removal of the repository reference, the referenced image itself will attempt to be deleted as described below but quietly, meaning any image delete conflicts will cause the image to not be deleted and the conflict will not be reported.

There may be conflicts preventing deletion of an image and these conflicts are divided into two categories grouped by their severity:

Hard Conflict:

  • a pull or build using the image.
  • any descendent image.
  • any running container using the image.

Soft Conflict:

  • any stopped container using the image.
  • any repository tag or digest references to the image.

The image cannot be removed if there are any hard conflicts and can be removed if there are soft conflicts only if force is true.

If prune is true, ancestor images will each attempt to be deleted quietly, meaning any delete conflicts will cause the image to not be deleted and the conflict will not be reported.

FIXME: remove ImageDelete's dependency on Daemon, then move to the graph package. This would require that we no longer need the daemon to determine whether images are being used by a stopped or running container.

func (*Daemon) ImageGetCached added in v1.2.0 

func (daemon *Daemon) ImageGetCached(imgID image.ID, config *containertypes.Config) (*image.Image, error)
