What's new?

New S3 storage driver
The default s3 storage driver is now implemented on top of the official Amazon
S3 SDK, boasting major performance and stability goodness. The previous storage
is still available, but deprecated.

Garbage Collector
A garbage collector command has been added to the registry.

Tagged Manifest Events
Manifest push and pull events will now include the tag which was used in the
operation (if applicable).

Relative URLs
The registry can now be configured to return relative URLs in Location headers.

V1 Signature disabled
With the ongoing adoption of the schema 2 manifest format and deprecation of
signatures, this option will improve pull performance by generating and
returning a single libtrust signature.

Gotchas

The RADOS storage driver has been removed. The registry can still be used with
Ceph as the storage backend using the swift driver in conjunction with the Swift
API gateway.

The command line format has changed to support subcommands. To run a registry as
before an additional subcommand - serve - is required.

The legacy S3 storage driver, based on adroll/goamz is now deprecated and will
be removed in a future release.

Docker Registry v2.3.0

What’s new?

This Docker Registry release is the first to support the Image Manifest Version 2, Schema 2
manifest format.

This new schema version has two primary goals. The first is to move the Docker
engine towards content-addressable images, by supporting an image model where
the image's configuration can be hashed to generate an ID for the image. The
second is to allow multi-architecture images, through a "fat manifest" which
references image manifests for platform-specific versions of an image.

For details, see https://github.com/docker/distribution/blob/master/docs/spec/manifest-v2-2.md

Cross Repository Blob Mount

Previously the registry required all blob data to be uploaded to a repository,
even if it existed in the Registry’s blob store.  This was a security measure to
ensure the clients owned the data they intended to upload.

Cross Repository Mount now enables an existing blob to be mounted into the target
repository if it already exists in a repository which the user has pull access
to.  This can reduce the amount of data transferred when pushing images.

For details, see: https://github.com/docker/distribution/issues/634

Additionally there are a number of performance improvements, bug fixes and
documentation updates.

Gotchas

In certain cases, pull by digest will not work.  For details, see
https://github.com/docker/distribution/blob/master/docs/compatibility.md

Fixes a bug where the incorrect digest and size were sent in manifest push
events for schema 1 manifests.

A bug is fixed where the incorrect content type for Schema 1 manifests was
returned.

Docker Registry v2.3 alpha release with support for multiple architectures
and cross repository blob mounting.

Docker Registry v2.2.1

Patch release of Docker Registry 2.2 incorporating bug fixes, documentation and
performance improvements.  Official distributions of this release will be built
with go 1.5.2.

Docker Registry v2.2

This Docker Registry release brings a new storage driver implementation to the
Docker Registry along with bug fixes, documentation enhancements and logging
improvements.

What’s new?

Google Cloud Storage Driver
The Registry now supports Google's reliable and fast network and storage
infrastructure for layer and manifest storage.

Read-only mode
Enables a Registry to serve only read requests, useful to maintain read
availability during unsafe administrative tasks.

Configurable hostname support
Allows the specification of an externally-reachable URL for the Registry.

Improved handling of environmental variables
Enables environment variables to be specified which are not part of the
configuration file.

Configurable file-existence and HTTP health checks
Allows administrators to easily disable a registry temporarily by placing a file
on the filesystem.  Additionally a registry can be configured to check the
health of other services, such as notification endpoints.

Enable configurable HTTP headers to be set in responses
This feature is usable for Registry administrators to set response headers for
various uses cases including increased security.

Redirect Support in the Swift Driver
The Swift storage driver now supports generating download URLs in line with
other cloud storage drivers.

Gotchas

In order to support valid hostnames as name components, supporting repeated dash
was added.  Additionally double underscore is now allowed as a separator to
loosen the restriction for previously supported names.

v2.1.1: Patch release of Docker Registry 2.1

This release provides a bug fix where the filesystem layout of manifests was
not backwards compatible with v2.0.x registries.
