A couple posts ago, we saw how signals are handled by applications, containers and pods and how this is affected by container specific details. With this post as a starting point, I went down the rabbit hole of Bash shell commands, processes and signals.

I do not know why I picked The Rebel by Camus, I never know why I pick my books, but for sure it is one of the most challenging reads I have had for a long time. The challenges laid on the the concepts that were introduced and referenced, which I had to look up and digest. Not an easy philosophical essay but surely worthy.

When shutting down an application, a container or a pod, we want it to happen smoothly, all serving requests to be completed and resources to be properly released. For this to happen, we need the signal to be propagated from the source (pod, container, OS) to the application.

Disclaimer: This blog post is my notes and interpretation on concepts and ideas presented in the book together with some personal reflections from my personal experience and career.
