Renew minikube certs when expire

[masalinas]

What Happened?

I deployed minikube one year ago, and now my certs expired, so I can't start minikube again. How Can I renew my certs to continue using my minikube cluster?

Attach the log file

I lost my logs because

Operating System

Ubuntu

Driver

Docker

Thank you for sharing your experience! If you don't mind, could you provide minikube logs ? I believe we do have codes that does exactly that and we fixed this a couple years ago, Please attach (drag) thelogs.txt file to this issue which can be generated by running this command:

$ minikube logs --file=logs.txt

This will help us isolate the problem further. Thank you!

I was investigating the past week abput this problem, and unfortunately I crush my original kubernetes image with a new one. But I would like to know how I can renew this certificates when it happens to me next time.

I discovered that by default now the default years of expiration is three and also you can use this paramater when start your minikube --cert-expiration=26280h0m0s, to configure this expiration, but exist a way to renew these certifcates after been created?, I think this is a recurrent question.

Hi @masalinas, this should be fixed (https://github.com/kubernetes/minikube/pull/16249), could you please tell us the version of minikube you're using, you may be on an outdated version that doesn't have the fix.
