Red Hat Quay 3.1 Features Repository Mirroring

0

Red Hat has announced the availability of the latest version of Red Hat Quay — a distributed, highly available container registry for enterprises. Red Hat Quay 3.1 builds on the focus to help users store, build and deploy their images in a more secure way across diverse enterprise environments and to leverage several new backend technologies, the open source company said.

The latest version enables the availability of repository mirroring, a new Kubernetes Operator for a more streamlined setup, a new repository mode to support archived or (temporarily) frozen repositories and enhancements for storage and database support.

The newest Quay feature is repository mirroring, supported in Technology Preview. It complements Red Hat’s existing geographic replication features. Quay geo-replication is designed for a shared, global registry. It mirrors the entire storage backend data between two or more different storage backends while the database, and therefore the entire Quay configuration and data, is shared. The primary use case for geo-replication is to speed up access to the binary blobs for geographically dispersed setups while content is the same across regions.

Repository mirroring takes this a step further for more diverse use cases. It has been designed for mirroring content between distinct, different registries. With repo mirroring in Quay, customers can continually synchronize repositories from external source registries into Quay (content ingress point), mirror a subset of the entire registry content to distributed deployments as well as set up and apply filters to sync a smaller subset of a repository using tag filters.

Red Hat said that it will continue working on a number of updates for Quay in future too.
