Constants

const MediaTypeManifestList = "application/vnd.docker.distribution.manifest.list.v2+json"

MediaTypeManifestList specifies the mediaType for manifest lists.

Variables

var SchemaVersion = manifest.Versioned{
	SchemaVersion: 2,
	MediaType:     MediaTypeManifestList,
}

SchemaVersion provides a pre-initialized version structure for this packages version of the manifest.

Types

type DeserializedManifestList

type DeserializedManifestList struct {
	ManifestList
	// contains filtered or unexported fields
}

DeserializedManifestList wraps ManifestList with a copy of the original JSON.

func FromDescriptors

func FromDescriptors(descriptors []ManifestDescriptor) (*DeserializedManifestList, error)

FromDescriptors takes a slice of descriptors, and returns a DeserializedManifestList which contains the resulting manifest list and its JSON representation.

func (*DeserializedManifestList) MarshalJSON

func (m *DeserializedManifestList) MarshalJSON() ([]byte, error)

MarshalJSON returns the contents of canonical. If canonical is empty, marshals the inner contents.

func (DeserializedManifestList) Payload

func (m DeserializedManifestList) Payload() (string, []byte, error)

Payload returns the raw content of the manifest list. The contents can be used to calculate the content identifier.

func (*DeserializedManifestList) UnmarshalJSON

func (m *DeserializedManifestList) UnmarshalJSON(b []byte) error

UnmarshalJSON populates a new ManifestList struct from JSON data.

type ManifestDescriptor

type ManifestDescriptor struct {
	distribution.Descriptor

	// Platform specifies which platform the manifest pointed to by the
	// descriptor runs on.
	Platform PlatformSpec `json:"platform"`
}

A ManifestDescriptor references a platform-specific manifest.

type ManifestList

type ManifestList struct {
	manifest.Versioned

	// Config references the image configuration as a blob.
	Manifests []ManifestDescriptor `json:"manifests"`
}

ManifestList references manifests for various platforms.

func (ManifestList) References

func (m ManifestList) References() []distribution.Descriptor

References returnes the distribution descriptors for the referenced image manifests.

type PlatformSpec

type PlatformSpec struct {
	// Architecture field specifies the CPU architecture, for example
	// `amd64` or `ppc64`.
	Architecture string `json:"architecture"`

	// OS specifies the operating system, for example `linux` or `windows`.
	OS string `json:"os"`

	// Variant is an optional field specifying a variant of the CPU, for
	// example `ppc64le` to specify a little-endian version of a PowerPC CPU.
	Variant string `json:"variant,omitempty"`

	// Features is an optional field specifuing an array of strings, each
	// listing a required CPU feature (for example `sse4` or `aes`).
	Features []string `json:"features,omitempty"`
}

PlatformSpec specifies a platform where a particular image manifest is applicable.
