Functions

func NewCacheResultStorage

func NewCacheResultStorage(wc *Controller) solver.CacheResultStorage

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. The first worker becomes the default.

Add is not thread-safe.

func (*Controller) Close

func (c *Controller) Close() error

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) Infos

func (c *Controller) Infos() Infos

func (*Controller) List

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

List lists workers

func (*Controller) WorkerInfos

func (c *Controller) WorkerInfos() []client.WorkerInfo

WorkerInfos returns slice of WorkerInfo. The first item is the default worker.

type Infos

type Infos interface {
	DefaultCacheManager() (cache.Manager, error)
	WorkerInfos() []client.WorkerInfo
}

type Worker

type Worker interface {
	io.Closer
	// ID needs to be unique in the cluster
	ID() string
	Labels() map[string]string
	Platforms(noCache bool) []ocispecs.Platform
	BuildkitVersion() client.BuildkitVersion

	GCPolicy() []client.PruneInfo
	LoadRef(ctx context.Context, id string, hidden bool) (cache.ImmutableRef, error)
	// ResolveOp resolves Vertex.Sys() to Op implementation.
	ResolveOp(v solver.Vertex, s frontend.FrontendLLBBridge, sm *session.Manager) (solver.Op, error)
	ResolveSourceMetadata(ctx context.Context, op *pb.SourceOp, opt sourceresolver.Opt, sm *session.Manager, g session.Group) (*sourceresolver.MetaResponse, error)
	DiskUsage(ctx context.Context, opt client.DiskUsageInfo) ([]*client.UsageInfo, error)
	Exporter(name string, sm *session.Manager) (exporter.Exporter, error)
	Prune(ctx context.Context, ch chan client.UsageInfo, opt ...client.PruneInfo) error
	FromRemote(ctx context.Context, remote *solver.Remote) (cache.ImmutableRef, error)
	PruneCacheMounts(ctx context.Context, ids map[string]bool) error
	ContentStore() *containerdsnapshot.Store
	Executor() executor.Executor
	CacheManager() cache.Manager
	LeaseManager() *leaseutil.Manager
	GarbageCollect(context.Context) error
}

type WorkerRef

type WorkerRef struct {
	ImmutableRef cache.ImmutableRef
	Worker       Worker
}

func (*WorkerRef) GetRemotes

func (wr *WorkerRef) GetRemotes(ctx context.Context, createIfNeeded bool, refCfg cacheconfig.RefConfig, all bool, g session.Group) ([]*solver.Remote, error)

GetRemotes method abstracts ImmutableRef's GetRemotes to allow a Worker to override. This is needed for moby integration. Use this method instead of calling ImmutableRef.GetRemotes() directly.

func (*WorkerRef) ID

func (wr *WorkerRef) ID() string

func (*WorkerRef) Release

func (wr *WorkerRef) Release(ctx context.Context) error
