Types

type MutableSource

type MutableSource struct {
	ProxySource
	// contains filtered or unexported fields
}

func NewMutableSource

func NewMutableSource(r types.ImageReference) (*MutableSource, error)

func (*MutableSource) AppendConfigHistory

func (m *MutableSource) AppendConfigHistory(author string, emptyLayer bool)

func (*MutableSource) AppendLayer

func (m *MutableSource) AppendLayer(content []byte, author string) error

appendLayer appends an uncompressed blob to the image, preserving the invariants required across the config and manifest.

func (*MutableSource) Config

func (m *MutableSource) Config() *manifest.Schema2Config

func (*MutableSource) Env

func (m *MutableSource) Env() map[string]string

Env returns a map of environment variables stored in the image config Converts each variable from a string of the form KEY=VALUE to a map of KEY:VALUE

func (*MutableSource) GetBlob

func (m *MutableSource) GetBlob(bi types.BlobInfo) (io.ReadCloser, int64, error)

GetBlob first checks the stored "extra" blobs, then proxies the call to the original source.

func (*MutableSource) GetManifest

func (m *MutableSource) GetManifest(_ *digest.Digest) ([]byte, string, error)

Manifest marshals the stored manifest to the byte format.

func (*MutableSource) SetConfig

func (m *MutableSource) SetConfig(config *manifest.Schema2Config, author string, emptyLayer bool)

func (*MutableSource) SetEnv

func (m *MutableSource) SetEnv(envMap map[string]string, author string)

SetEnv takes a map of environment variables, and converts them to an array of strings in the form KEY=VALUE, and then sets the image config

type ProxyReference

type ProxyReference struct {
	types.ImageReference
	Src types.ImageSource
}

ProxyReference implements types.Reference by proxying calls to an underlying implementation.

func (*ProxyReference) NewImageSource

func (p *ProxyReference) NewImageSource(ctx *types.SystemContext) (types.ImageSource, error)

type ProxySource

type ProxySource struct {
	Ref types.ImageReference
	types.ImageSource
	// contains filtered or unexported fields
}

ProxySource is a type that implements types.ImageSource by proxying all calls to an underlying implementation.

func NewProxySource

func NewProxySource(ref types.ImageReference) (*ProxySource, error)

func (*ProxySource) LayerInfosForCopy

func (p *ProxySource) LayerInfosForCopy() []types.BlobInfo

func (*ProxySource) Reference

func (p *ProxySource) Reference() types.ImageReference
