I have a kubernetes cluster and I've been experimenting so far with cert-manager and letsencrypt ssl certificates.
Everything goes fine, I have issued an SSL certificate and applied to the cluster and https connection is working excellent.
The problem I face is that I am experimenting with new things and it often leads me to delete the whole cluster and create a new fresh one, which on it's side makes me lose the SSL certificate and issue a new one, but there's a rate limit by 50 certificates per week per domain.
Is there a way I can reuse a certificate in a new k8s cluster?
Copy the secret locally ( kubectl get secret -o yaml
and then clean up unneeded fields) and then upload it to the new cluster ( kubectl apply
).
