Types

type ImageDestination 

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

ImageDestination is a reference of a remote image we will push to

func NewImageDestination 

func NewImageDestination(registry, repository, tagOrDigest, username, password string, insecure bool) (*ImageDestination, error)

NewImageDestination generates an ImageDestination by repository, the repository string must include tag or digest. If username or password is empty, access to repository will be anonymous.

func (*ImageDestination) CheckBlobExist added in v1.1.0 

func (i *ImageDestination) CheckBlobExist(blobInfo types.BlobInfo) (bool, error)

CheckBlobExist checks if a blob exist for destination and reuse exist blobs

func (*ImageDestination) CheckManifestChanged added in v1.4.0 

func (i *ImageDestination) CheckManifestChanged(destManifestBytes []byte, instanceDigest *digest.Digest) bool

CheckManifestChanged checks if manifest of specified tag or digest has changed.

func (*ImageDestination) Close 

func (i *ImageDestination) Close() error

Close a ImageDestination

func (*ImageDestination) GetManifest added in v1.4.0 

func (i *ImageDestination) GetManifest(instanceDigest *digest.Digest) []byte

func (*ImageDestination) GetRegistry 

func (i *ImageDestination) GetRegistry() string

GetRegistry returns the registry of a ImageDestination

func (*ImageDestination) GetRepository 

func (i *ImageDestination) GetRepository() string

GetRepository returns the repository of a ImageDestination

func (*ImageDestination) GetTagOrDigest added in v1.5.0 

func (i *ImageDestination) GetTagOrDigest() string

GetTagOrDigest return the tag or digest of a ImageDestination

func (*ImageDestination) PushManifest 

func (i *ImageDestination) PushManifest(manifestByte []byte, instanceDigest *digest.Digest) error

PushManifest push a manifest file to destination image. If instanceDigest is not nil, it contains a digest of the specific manifest instance to write the manifest for (when the primary manifest is a manifest list); this should always be nil if the primary manifest is not a manifest list.

func (*ImageDestination) PutABlob 

func (i *ImageDestination) PutABlob(blob io.ReadCloser, blobInfo types.BlobInfo) error

PutABlob push a blob to destination image

func (*ImageDestination) String added in v1.5.0 

func (i *ImageDestination) String() string

type ImageSource 

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

ImageSource is a reference to a remote image need to be pulled.

func NewImageSource 

func NewImageSource(registry, repository, tagOrDigest, username, password string, insecure bool) (*ImageSource, error)

NewImageSource generates a PullTask by repository, the repository string must include tag or digest, or it can only be used to list tags. If username or password is empty, access to repository will be anonymous. A repository string is the rest part of the images url except tag digest and registry

func (*ImageSource) Close 

func (i *ImageSource) Close() error

Close an ImageSource

func (*ImageSource) GetABlob 

func (i *ImageSource) GetABlob(blobInfo types.BlobInfo) (io.ReadCloser, int64, error)

GetABlob gets a blob from remote image

func (*ImageSource) GetBlobInfos 

func (i *ImageSource) GetBlobInfos(manifestObjSlice ...manifest.Manifest) ([]types.BlobInfo, error)

GetBlobInfos get blob infos from non-list type manifests.

func (*ImageSource) GetManifest 

func (i *ImageSource) GetManifest() ([]byte, string, error)

GetManifest get manifest file from source image

func (*ImageSource) GetRegistry 

func (i *ImageSource) GetRegistry() string

GetRegistry returns the registry of a ImageSource

func (*ImageSource) GetRepository 

func (i *ImageSource) GetRepository() string

GetRepository returns the repository of a ImageSource

func (*ImageSource) GetSourceRepoTags 

func (i *ImageSource) GetSourceRepoTags() ([]string, error)

GetSourceRepoTags gets all the tags of a repository which ImageSource belongs to

func (*ImageSource) GetTagOrDigest added in v1.5.0 

func (i *ImageSource) GetTagOrDigest() string

GetTagOrDigest returns the tag or digest a ImageSource

func (*ImageSource) String added in v1.5.0 

func (i *ImageSource) String() string

type ManifestInfo added in v1.4.0 

type ManifestInfo struct {
	Obj    manifest.Manifest
	Digest *digest.Digest

	// (manifest.Manifest).Serialize() does not in general reproduce the original blob if this object was loaded from one,
	// even if no modifications were made! Non-list type image seems cannot use the result to push to dest
	// repo while it is a part of list-type image.
	Bytes []byte
}

func GenerateManifestObj added in v1.4.0 

func GenerateManifestObj(manifestBytes []byte, manifestType string, osFilterList, archFilterList []string,
	i *ImageSource, parent *manifest.Schema2List) (interface{}, []byte, []*ManifestInfo, error)

GenerateManifestObj returns a new manifest object along with its byte serialization, and a sub manifest object array, and a digest array of sub manifests for list-type manifests. For list type manifest, the origin manifest info might be modified because of platform filters, and a nil manifest object will be returned if no sub manifest need to transport.
