@ -103,20 +103,20 @@ via IRC or the mailing list and we can talk about adding it. The goal here is
|
|||
to make sure that new features go through a rigid design process before
|
||||
landing in the registry.
|
||||
|
||||
##### Mirroring and Pull-through Caching
|
||||
##### Proxying to other Registries
|
||||
|
||||
Mirroring and pull-through caching are related but slight different. We've
|
||||
adopted the term _mirroring_ to be a proper mirror of a registry, meaning it
|
||||
has all the content the upstream would have. Providing such mirrors in the
|
||||
Docker ecosystem is dependent on a solid trust system, which is still in the
|
||||
works.
|
||||
A _pull-through caching_ mode exists for the registry, but is restricted from
|
||||
within the docker client to only mirror the official Docker Hub. This functionality
|
||||
can be expanded when image provenance has been specified and implemented in the
|
||||
distribution project.
|
||||
|
||||
The more commonly helpful feature is _pull-through caching_, where data is
|
||||
fetched from an upstream when not available in a local registry instance.
|
||||
##### Metadata storage
|
||||
|
||||
Please see the following issues:
|
||||
|
||||
- https://github.com/docker/distribution/issues/459
|
||||
Metadata for the registry is currently stored with the manifest and layer data on
|
||||
the storage backend. While this is a big win for simplicity and reliably maintaining
|
||||
state, it comes with the cost of consistency and high latency. The mutable registry
|
||||
metadata operations should be abstracted behind an API which will allow ACID compliant
|
||||
storage systems to handle metadata.

||||
|
||||
##### Peer to Peer transfer
