func (d *Docker) Commit(cacheKey string, hook executor.Hook) error

Commit commits an entry to the layer list.

func (*Docker) Config ¶

func (d *Docker) Config() *config.Config

Config returns the current *Config for the executor.

func (*Docker) CopyFromContainer ¶

func (d *Docker) CopyFromContainer(id, path string) (io.Reader, int64, error)

CopyFromContainer copies a series of files in a similar fashion to CopyToContainer, just in reverse.

func (*Docker) CopyOneFileFromContainer ¶

func (d *Docker) CopyOneFileFromContainer(fn string) ([]byte, error)

CopyOneFileFromContainer copies a file from the container and returns its content. An error is returned, if any.

func (*Docker) CopyToContainer ¶

func (d *Docker) CopyToContainer(id string, r io.Reader) error

CopyToContainer copies files from the tarfile specified in reader to the containerto the container so it can then be committed. It does not close the reader.

func (*Docker) Create ¶

func (d *Docker) Create() (string, error)

Create creates a new container based on the existing configuration.

func (*Docker) Destroy ¶

func (d *Docker) Destroy(id string) error

Destroy destroys a container for the given id.

func (*Docker) Fetch ¶

func (d *Docker) Fetch(name string) (string, error)

Fetch retrieves a docker image, overwrites the container configuration, and returns its id.

func (*Docker) Flatten ¶ added in v0.3.1

func (d *Docker) Flatten(id string, size int64, tw io.Reader) error

Flatten copies a tarred up series of files (passed in through the io.Reader handle) to the image where they are untarred.

func (*Docker) ImageID ¶

func (d *Docker) ImageID() string

ImageID returns the image identifier of the most recent layer.

func (*Docker) LoadConfig ¶

func (d *Docker) LoadConfig(c *config.Config) error

LoadConfig loads the configuration into the executor.

func (*Docker) MakeImage ¶ added in v0.3.1

func (d *Docker) MakeImage() error

MakeImage makes the final image, skipping any layers as necessary. The layers must be pre-recorded within the executor. Note that if you have no layers to skip, this operation will need to do nothing, so it will do nothing.

It returns an error condition, if any.

func (*Docker) RunHook ¶

func (d *Docker) RunHook(id string) (string, error)

RunHook is the run hook for docker agents.

func (*Docker) SetSkipLayers ¶ added in v0.3.1

func (d *Docker) SetSkipLayers(ok bool)

SetSkipLayers toggles whether or not to skip layers when building the final image.

func (*Docker) SetStdin ¶

func (d *Docker) SetStdin(on bool)

SetStdin turns on the stdin features during run invocations. It is used to facilitate debugging.

func (*Docker) Tag ¶

func (d *Docker) Tag(tag string) error

Tag an image with the provided string.

func (*Docker) UseCache ¶

func (d *Docker) UseCache(arg bool)

UseCache determines if the cache should be considered or not.

func (*Docker) UseTTY ¶

func (d *Docker) UseTTY(arg bool)

UseTTY determines whether or not to allow docker to use a TTY for both run and pull operations.
