Document URL: https://docs.openshift.com/enterprise/3.1/install_config/upgrades.html#upgrading-masters Section Number and Name: Create the following master proxy client certificates: Describe the issue: With 3.1 the master need the following hostname added to the certs. All certs in the master would need the following hostnames: kubernetes, kubernetes.default, kubernetes.default.svc, kubernetes.default.svc.cluster.local, master.example.com, Dopenshift, openshift.default, openshift.default.svc, openshift.default.svc.cluster.local, 10.3.8.242, 172.17.28.5, 172.30.0.1, IP Address:10.3.8.242, IP Address:172.17.28.5, IP Address:172.30.0.1 Suggestions for improvement: Would need to recreate the following certs and keys: etcd.server.crt etcd.server.key master.proxy-client.crt master.proxy-client.key master.server.crt master.server.key
Why do the etcd server certs need to be regenerated?
The hostnames were updated: https://docs.openshift.com/enterprise/3.1/install_config/upgrading/manual_upgrades.html#manual-checking-the-masters-certificate. Closing this bug.
