Functions

func Set

func Set(ctx context.Context, source, target ocispec.Descriptor)

Types

type Item

type Item struct {
	Source ocispec.Descriptor
	Target ocispec.Descriptor
}

type Provider

type Provider interface {
	Resolver(ref string) (remotes.Resolver, error)
	Pull(ctx context.Context, ref string) error
	Push(ctx context.Context, desc ocispec.Descriptor, ref string) error
	ContentStore() content.Store
}

type RemoteCache

type RemoteCache struct {
	// ref is the reference of cache manifest in remote registry.
	Ref string
	// contains filtered or unexported fields
}

RemoteCache manages the map of source and target layer after conversion, it's local records of the remote cache manifest.

func Get

func Get(ctx context.Context, dgst digest.Digest) (*RemoteCache, *ocispec.Descriptor)

func New

func New(ctx context.Context, ref, version string, size int, pvd Provider) (context.Context, *RemoteCache)

func Update

func Update(ctx context.Context, dgst digest.Digest, labels map[string]string) (*RemoteCache, *ocispec.Descriptor)

func (*RemoteCache) Fetch

func (rc *RemoteCache) Fetch(ctx context.Context, platformMC platforms.MatchComparer) (*ocispec.Descriptor, error)

Fetch fetchs cache manifest from remote registry.

func (*RemoteCache) HitCount

func (rc *RemoteCache) HitCount(ctx context.Context, desc ocispec.Descriptor, platform platforms.MatchComparer) (uint, uint, error)

HitCount returns the hitted and total count of cache layers in a conversion.

func (*RemoteCache) Push

func (rc *RemoteCache) Push(ctx context.Context, orgDesc, newDesc *ocispec.Descriptor, platformMC platforms.MatchComparer) error

Push merges local and remote cache records, then push cache manifest to remote registry.
