Dockerizing a Gatsby Site
Just recently I started to migrate my blog from Hugo to Gatsby. Gatsby is also a static site generator but it is a lot more flexible than others. While a generator like Hugo only provides a way to build a static site based on markdown files, Gatsby is more like a framework to build whatever…

In some situations it can happen that a pod or a full node is not available anymore but Kubernetes thinks it is still there. For example, I had a case where a worker node was deleted via the cloud provider API (not via Kubernetes) and Kubernetes did not properly notice this interruption. Then I tried…
