5.2. Add repository mirroring Red Hat Quay
Enabling repository mirroring allows you to create container image repositories on your Red Hat Quay cluster that exactly match the content of a selected external registry, then sync the contents of those repositories on a regular schedule and on demand.
To add the repository mirroring feature to your Red Hat Quay cluster:
-
Run the repository mirroring worker. To do this, you start a quay pod with the
repomirroroption. - Select "Enable Repository Mirroring in the Red Hat Quay Setup tool.
- Log into your Red Hat Quay Web UI and begin creating mirrored repositories as described in Repository Mirroring in Red Hat Quay.
The following procedure assumes you already have a running Red Hat Quay cluster on an OpenShift platform, with the Red Hat Quay Setup container running in your browser:
Start the repo mirroring worker: Start the
Quaycontainer inrepomirrormode. This example assumes you have configured TLS communications using a certificate that is currently stored in/root/ca.crt. If not, then remove the line that adds/root/ca.crtto the container:$ sudo podman run -d --name mirroring-worker \ -v /mnt/quay/config:/conf/stack:Z \ -v /root/ca.crt:/etc/pki/ca-trust/source/anchors/ca.crt \ registry.redhat.io/quay/quay-rhel8:v3.15.4 repomirror- Log into config tool: Log into the Red Hat Quay Setup Web UI (config tool).
- Enable repository mirroring: Scroll down the Repository Mirroring section and select the Enable Repository Mirroring check box, as shown here:
-
Select HTTPS and cert verification: If you want to require HTTPS communications and verify certificates during mirroring, select this check box.
- Save configuration: Select the Save Configuration Changes button. Repository mirroring should now be enabled on your Red Hat Quay cluster. Refer to Repository Mirroring in Red Hat Quay for details on setting up your own mirrored container image repositories.
