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
