Opt defines a structure for creating a worker.

type Worker

type Worker struct {
	Opt
	SourceManager *source.Manager
}

Worker is a local worker instance with dedicated snapshotter, cache, and so on. TODO: s/Worker/OpWorker/g ?

func NewWorker

func NewWorker(opt Opt) (*Worker, error)

NewWorker instantiates a local worker

func (*Worker) DiskUsage

func (w *Worker) DiskUsage(ctx context.Context, opt client.DiskUsageInfo) ([]*client.UsageInfo, error)

DiskUsage returns disk usage report

func (*Worker) Exec

func (w *Worker) Exec(ctx context.Context, meta executor.Meta, rootFS cache.ImmutableRef, stdin io.ReadCloser, stdout, stderr io.WriteCloser) error

Exec executes a process directly on a worker

func (*Worker) Exporter

func (w *Worker) Exporter(name string) (exporter.Exporter, error)

Exporter returns exporter by name

func (*Worker) FromRemote

func (w *Worker) FromRemote(ctx context.Context, remote *solver.Remote) (cache.ImmutableRef, error)

FromRemote converts a remote snapshot reference to a local one

func (*Worker) GCPolicy

func (w *Worker) GCPolicy() []client.PruneInfo

GCPolicy returns automatic GC Policy

func (*Worker) GetRemote

func (w *Worker) GetRemote(ctx context.Context, ref cache.ImmutableRef, createIfNeeded bool) (*solver.Remote, error)

GetRemote returns a remote snapshot reference for a local one

func (*Worker) ID

ID returns worker ID

func (*Worker) Labels

func (w *Worker) Labels() map[string]string

Labels returns map of all worker labels

func (*Worker) LoadRef

func (w *Worker) LoadRef(id string, hidden bool) (cache.ImmutableRef, error)

LoadRef loads a reference by ID

func (*Worker) Platforms

func (w *Worker) Platforms() []ocispec.Platform

Platforms returns one or more platforms supported by the image.

func (*Worker) Prune

func (w *Worker) Prune(ctx context.Context, ch chan client.UsageInfo, info ...client.PruneInfo) error

Prune deletes reclaimable build cache

func (*Worker) ResolveImageConfig

func (w *Worker) ResolveImageConfig(ctx context.Context, ref string, opt gw.ResolveImageConfigOpt) (digest.Digest, []byte, error)

ResolveImageConfig returns image config for an image
