[Airship-discuss] Kubernetes Certificates Expiring, how to renew in Airship?

[Rhine, Jay (Nokia - US)]

Hello!

               Our ingress certs expire often and we know how to replace them, but the system ones we are not sure on.  If you can share those steps, it would be great.

Thanks,

Jay

Hello Jay,

Hope you are doing good.
We don't have the cert-rotation scripts ready for upstream.

We shall share some steps to rotate the K8s certs shortly.

Also would request you to check the ingress cert expiration dates.

BR,
Arijit Bose

Hello!  I sent this after normal working hours for same last week, so I'll resend this request again ... any ideas are appreciated.

We have an airship system that we have been using, and we have noticed that many of the certificates in /etc/kubernetes will expire soon.  In particular, these certificates:

/etc/kubernetes/scheduler/scheduler.pem
/etc/kubernetes/admin/pki/admin.pem
/etc/kubernetes/controller-manager/controller-manager.pem
/etc/kubernetes/apiserver/apiserver-proxy-cert.pem
/etc/kubernetes/apiserver/pki/apiserver.pem
/etc/kubernetes/apiserver/pki/apiserver-both.pem
/etc/kubernetes/apiserver/pki/etcd-client.pem
/etc/kubernetes/apiserver/pki/kubelet-client.pem
/etc/kubernetes/pki/kubelet.pem

Is there a procedure, script, or guidance on how we can renew those certificates?  We looked around online a bit, and the generic procedures seemed to mostly refer to kubeadm, which I don't think is being used by airship.

Any suggestions would be appreciated.

Thank you!

Jay
