Did an upgrade of the NGINX Ingress Controller and it was easier then I thought.

If you want to migrate to v1.0.0 every ingress resources needs to be first on the new apiVersion “networking.k8s.io/v1” and your Kubernetes cluster must be at least on minor version 19 (v1.19.x).

Let me make a small example. In the past…

Let me start with the thinking process. When I set my own…


Just do it. Sometimes we have a habit and we break it as soon as we are getting out of our “perfect” mood. Today I try to keep my habit running even if it is hard. Had the feeling I am mentally totally exhausted for today and won’t be able…


Last twelve months were crazy. The relationship I thought will be the last, was not. My dad passed away. The pandemic hit. My uncle and his wife died in a horrific car crash. I moved to Lithuania from one day to another to help. Decided that I do not want…
