Functions

func NewWorkerRefResult

func NewWorkerRefResult(ref cache.ImmutableRef, worker Worker) solver.Result

Types

type Controller

type Controller struct {
	// contains filtered or unexported fields
}

Controller holds worker instances. Currently, only local workers are supported.

func (*Controller) Add

func (c *Controller) Add(w Worker) error

Add adds a local worker

func (*Controller) Get

func (c *Controller) Get(id string) (Worker, error)

func (*Controller) GetDefault

func (c *Controller) GetDefault() (Worker, error)

GetDefault returns the default local worker

func (*Controller) List

func (c *Controller) List(filterStrings ...string) ([]Worker, error)

List lists workers

type Worker

type Worker interface {
	// ID needs to be unique in the cluster
	ID() string
	Labels() map[string]string
	LoadRef(id string) (cache.ImmutableRef, error)
	// ResolveOp resolves Vertex.Sys() to Op implementation.
	ResolveOp(v solver.Vertex, s frontend.FrontendLLBBridge) (solver.Op, error)
	ResolveImageConfig(ctx context.Context, ref string) (digest.Digest, []byte, error)
	// Exec is similar to executor.Exec but without []mount.Mount
	Exec(ctx context.Context, meta executor.Meta, rootFS cache.ImmutableRef, stdin io.ReadCloser, stdout, stderr io.WriteCloser) error
	DiskUsage(ctx context.Context, opt client.DiskUsageInfo) ([]*client.UsageInfo, error)
	Exporter(name string) (exporter.Exporter, error)
	Prune(ctx context.Context, ch chan client.UsageInfo) error
	GetRemote(ctx context.Context, ref cache.ImmutableRef, createIfNeeded bool) (*solver.Remote, error)
	FromRemote(ctx context.Context, remote *solver.Remote) (cache.ImmutableRef, error)
}

type WorkerRef

type WorkerRef struct {
	ImmutableRef cache.ImmutableRef
	Worker       Worker
}

func (*WorkerRef) ID

func (wr *WorkerRef) ID() string
