1.2. Content distribution
Red Hat Quay content distribution covers repository mirroring, geo-replication, and disconnected or air-gapped deployment. You can sync images from other registries, present multiple geo-distributed deployments as one registry, or run in air-gapped environments.
- Repository mirroring
- Red Hat Quay repository mirroring lets you mirror images from Red Hat Quay and other container registries, like JFrog Artifactory, Harbor, or Sonatype Nexus Repository, into your Red Hat Quay cluster. Using repository mirroring, you can synchronize images to Red Hat Quay based on repository names and tags.
- Geo-replication
- Red Hat Quay geo-replication allows multiple, geographically distributed Red Hat Quay deployments to work as a single registry from the perspective of a client or user. It significantly improves push and pull performance in a globally-distributed Red Hat Quay setup. Image data is asynchronously replicated in the background with transparent failover and redirection for clients.
- Deployment in disconnected or air-gapped environments
Red Hat Quay is deployable in a disconnected environment in one of two ways:
- Red Hat Quay and Clair connected to the internet, with an air-gapped OpenShift Container Platform cluster accessing the Red Hat Quay registry through an explicit, allowlisted hole in the firewall.
- Using two independent Red Hat Quay and Clair installations. One installation is connected to the internet and another within a disconnected, or firewalled, environment. Image and vulnerability data is manually transferred from the connected environment to the disconnected environment using offline media.
