Container images

Artifact Registry supports the following container image formats:

• Docker Image Manifest V2, Schema 1
• Docker Image Manifest V2, Schema 2
• Open Container Initiative (OCI) Specifications

Docker V2

Docker V2 image manifest is a specification for container images that allows multi-architecture images and supports content-addressable images.

Docker V2 images supersede Docker V1 images, which are deprecated.

OCI format

The OCI format is a specification for container images based on the Docker Image Manifest Version 2, Schema 2 format. Artifact Registry supports pushing and pulling OCI images.

Manifest lists and image indexes

Manifest lists are part of the Docker V2, Schema 2 and OCI images.

Manifest lists allow a single digest or tag to represent multiple forms of an image.

Image indexes are the equivalent of manifest lists in OCI images.

Like manifest lists, an image index manifest refers to multiple image manifests. Image indexes are useful for multi-platform images.

Package formats

The following package types are supported:

• Maven (alpha)
• npm (alpha)

Note: Package management is only available to alpha users. To apply for the alpha, complete the sign up form.
