| + | ===== Admin Tasks ===== | ||
| + | ==== Renewing the SSL certiciate ==== | ||
| + | The first time I created the cert, I accidentally left the date out so the cert was only good for a month. The second cert is good for 10 years. | ||

| + | - Copy the contents of ''/lrc/certs/domain.crt'' and update ''container_mirror_cert'' in https://github.com/ceph/ceph-sepia-secrets/blob/master/ansible/inventory/group_vars/all.yml | ||
| + | - Run ''ansible-playbook container-host.yml'' against the appropriate hosts. | ||
| + | - ''%%root@docker-mirror:~# docker stop registry-mirror; docker rm registry-mirror; docker run -d --restart=always -p 5000:5000 --name registry-mirror -e REGISTRY_HTTP_TLS_CERTIFICATE=/var/lib/registry/certs/domain.crt -e REGISTRY_HTTP_TLS_KEY=/var/lib/registry/certs/domain.key -v /lrc:/var/lib/registry registry:2 /var/lib/registry/config.yml; docker logs -f registry-mirror%%'' | ||
