Functions

func DetectContextFromRemoteURL

func DetectContextFromRemoteURL(r io.ReadCloser, remoteURL string, createProgressReader func(in io.ReadCloser) io.ReadCloser) (context builder.ModifiableContext, dockerfileName string, err error)

DetectContextFromRemoteURL returns a context and in certain cases the name of the dockerfile to be used irrespective of user input. progressReader is only used if remoteURL is actually a URL (not empty, and not a Git endpoint).

Types

type Docker

type Docker struct {
	*daemon.Daemon
	OutOld      io.Writer
	AuthConfigs map[string]types.AuthConfig
	Archiver    *archive.Archiver
}

Docker implements builder.Backend for the docker Daemon object.

func (Docker) BuilderCopy

func (d Docker) BuilderCopy(cID string, destPath string, src builder.FileInfo, decompress bool) error

BuilderCopy copies/extracts a source FileInfo to a destination path inside a container specified by a container object. TODO: make sure callers don't unnecessarily convert destPath with filepath.FromSlash (Copy does it already). BuilderCopy should take in abstract paths (with slashes) and the implementation should convert it to OS-specific paths.

func (Docker) ContainerUpdateCmd

func (d Docker) ContainerUpdateCmd(cID string, cmd []string) error

ContainerUpdateCmd updates Path and Args for the container with ID cID.

func (Docker) GetCachedImage

func (d Docker) GetCachedImage(imgID string, cfg *runconfig.Config) (string, error)

GetCachedImage returns a reference to a cached image whose parent equals `parent` and runconfig equals `cfg`. A cache miss is expected to return an empty ID and a nil error.

func (Docker) Mount

func (d Docker) Mount(cID string) error

Mount mounts the root filesystem for the container.

func (Docker) Pull

func (d Docker) Pull(name string) (*image.Image, error)

Pull tells Docker to pull image referenced by `name`.

func (Docker) Release

func (d Docker) Release(sessionID string, activeImages []string)

Release releases a list of images that were retained for the time of a build.

func (Docker) Retain

func (d Docker) Retain(sessionID, imgID string)

Retain retains an image avoiding it to be removed or overwritten until a corresponding Release() call.

func (Docker) Unmount

func (d Docker) Unmount(cID string) error

Unmount unmounts the root filesystem for the container.
