 +Or you can also now just run the [[https://​github.com/​ceph/​ceph-cm-ansible/​tree/​master/​roles/​container-host|container-host role]] which will configure ''​podman''​ and/or ''​docker''​ to use our mirror for docker.io. 
 + 
 +===== 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. 
 + 
 +  - ''​%%root@docker-mirror:​~#​ openssl req  -newkey rsa:4096 -nodes -sha256 -keyout /​lrc/​certs/​domain.key -x509 -days 3650 -addext "​subjectAltName = DNS:​docker-mirror.front.sepia.ceph.com"​ -out /​lrc/​certs/​domain.crt%%''​ 
 +  - 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%%''​

 +===== Other Notes ===== 
 +The mirror logs in to dockerhub using my personal API key.  I just have a personal account but docker-mirror was getting rate-limited when anonymous.
