FetchConfig reads the specified file from the worker.ArtifactRepository and loads the TaskConfig contained therein (expecting it to be YAML format).

The path must be in the format SOURCE_NAME/FILE/PATH.yml. The SOURCE_NAME will be used to determine the ArtifactSource in the worker.ArtifactRepository to stream the file out of.

If the source name is missing (i.e. if the path is just "foo.yml"), UnspecifiedArtifactSourceError is returned.

If the specified source name cannot be found, UnknownArtifactSourceError is returned.

func (*GetAction) Run

func (action *GetAction) Run(
	logger lager.Logger,
	repository *worker.ArtifactRepository,

	signals <-chan os.Signal,
	ready chan<- struct{},
) error

Run ultimately registers the configured resource version's ArtifactSource under the configured SourceName. How it actually does this is determined by a few factors.

First, a worker that supports the given resource type is chosen, and a container is created on the worker.

If the worker has a VolumeManager, and its cache is already warmed, the cache will be mounted into the container, and no fetching will be performed. The container will be used to stream the contents of the cache to later steps that require the artifact but are running on a worker that does not have the cache.

If the worker does not have a VolumeManager, or if the worker does have a VolumeManager but a cache for the version of the resource is not present, the specified version of the resource will be fetched. As long as running the fetch script works, Run will return nil regardless of its exit status.

If the worker has a VolumeManager but did not have the cache initially, the fetched ArtifactSource is initialized, thus warming the worker's cache.

At the end, the resulting ArtifactSource (either from using the cache or fetching the resource) is registered under the step's SourceName.

type Step

type Step interface {
	// Run is called when it's time to execute the step. It should indicate when
	// it's ready, and listen for signals at points where the potential time is
	// unbounded (i.e. running a task or a resource action).
	//
	// Steps wrapping other steps should be careful to propagate signals and
	// indicate that they're ready as soon as their wrapped steps are ready.
	//
	// Steps should return ErrInterrupted if they received a signal that caused
	// them to stop.
	//
	// Steps must be idempotent. Each step is responsible for handling its own
	// idempotency; usually this is done by saving off "checkpoints" in some way
	// that can be checked again if the step starts running again from the start.
	// For example, by having the ID for a container be deterministic and unique
	// for each step, and checking for properties on the container to determine
	// how far the step got.

	// Succeeded is not guaranteed to be truthful until after you run Run()
