I think it’s since when I updated Arch Linux a while ago the tracker-storeprocess has become CPU-hogging and it can drain the battery pretty quickly and turn my laptop into a heater.

Get access to a container in Kubernetes cluster

There are still occasions when I need shell access to a container to do some troubleshooting. With Docker I can do It’s quite similar in K8s However in K8s containers have random IDs so I need to know the…
