Oh-my-zsh

Yesterday I finally installed oh-my-zsh. It was on my to-do list for longer time already, because I read so many good things about it… but having things on a todo list and finally taking the time for doing them is a big difference sometimes ;)

However, the installation went fine, and after that you can, or better to say have to spend some time on configuration, which basically means chosing a theme and the plugins you want to use.

A good thing about the installation is, that it took over the $PATH variable from the old shell. But unfortunately you now have one big export PATH=... line, while you probably had a more structered version before. At least I had. So I deleted that line from the config, and copied my old PATH config from the now unused bash configuration.

kubectl command completion

A few days ago I came across a small blog post about kubectl (the Kubernetes command line tool) command completion. That is really useful, so wanted to have that for zsh too, and I found this:

kubectl completion finally also for zsh https://github.com/kubernetes/kubernetes/pull/23262

I didn’t find instructions on how to add that to the zsh config, and it took me some minutes to find out, so I’d like to share it here:

  1. clone kubernetes master (the zsh completion is not in a release yet): git clone https://github.com/kubernetes/kubernetes.git
  2. add this to ~/.zshrc: source $HOME/path/to/kubernetes/contrib/completions/zsh/kubectl

I got an error at the first try, and it turned out that gnu-sed was the problem, which I had installed with brew. After uninstalling it, it worked fine: This issue will be solved soonish, see @the1stein’s tweet.

Kubectl command completion in action, it first completes the available k8s resources, and then the available deployments:
