The Rollback Worked. My Next Deploy Could Break It Again.

My application was working again. That should have been the end of the problem.

It was not.

In [the first article in this series(https://blog.lalitbagga.com/posts/why-i-chose-k3s-debian-homelab), I built an always on Kubernetes lab on my home server. I deployed a small application, changed it from Version 2 to Version 3, and then practised a rollback.

Kubernetes restored Version 2 successfully. But the YAML file on my computer the file containing the instructions for the application still said Version 3.

I had repaired what was running, but I had not repaired the instructions that I would use next time. If I applied that file again, I could accidentally bring Version 3 back.
