<dt>Why is this a problem?</dt>
<dd>Docker Hub has rather severe rate limits for image pulls. If we need to pull several images at once, e.g. to recover from a region-wide outage, the recovery may be significantly slowed down by the rate limiting.</p>
<dt>How to fix?</dt>
<dd>We have set up a Docker Hub mirror at <code>keppel.$REGION.cloud.sap/ccloud-dockerhub-mirror</code>. The regional mirror is defined in globals.yaml and can be referenced as <code>$.Values.dockerHubMirror</code> in most Helm charts (<a href="https://github.com/sapcc/helm-charts/blob/409aa9940ecb600dafc0f9a20c973566af9eaf1f/openstack/backup-replication/templates/statsd-deployment.yaml#L29">example</a>).<br><br>If a particular image has not been mirrored yet, you need to <code>docker pull</code> it once from eu-de-1 with your logged-in Docker client. Afterwards, the image can be pulled from all regions without login.</dd>

<dt>What about circular dependencies?</dt>
<dd>If your pod pulls an image from Keppel, but Keppel needs that pod up and running to work, that's probably not a good idea. Get in touch with Stefan Majewsky and we'll figure out how to proceed.</dd>
