Hi all,
I am just getting started with Kubernetes and the kubectl command specifically.
As there are so many flags and arguments, is there a way to enable autocompletion just like in git?
So for example when I type kubectl get no[TAB] it would autocomplete nodes.
Thank you!

Hi there,
Yes, this is doable. What you would need to do is to first to make sure that you have the bash-completion package installed. If not, you could install it with the following command:
sudo apt-get install -y bash-completion
After that, you could generate the required kubectl completion rules with the kubectl completion bash command, and then store the rules in your .bashrc file. You could use the following command to do that:
echo "source <(kubectl completion bash)" >> ~/.bashrc
Note: Make sure to run this only once so that you don’t get duplicated rules.
After that, use the source command to activate the new rules:
source ~/.bashrc
Finally, if you were not now run kubectl get no[TAB] it will be autocompleted.
This is indeed quite handy! Hope that this helps. Regards, Bobby
I would look at this page https://kubernetes.io/docs/reference/kubectl/cheatsheet/#kubectl-autocomplete
Essentially for:
Bash
source <(kubectl completion bash) # set up autocomplete in bash into the current shell, bash-completion package should be installed first.
echo "source <(kubectl completion bash)" >> ~/.bashrc # add autocomplete permanently to your bash shell
You could use it for aliases as I usually use k instead of the full kubectl command it is usefull
alias k=kubectl
complete -o default -F __start_kubectl k
ZSH
(kubectl completion zsh) # set up autocomplete in zsh into the current shell
echo '[[ $commands[kubectl] ]] && source <(kubectl completion zsh)' >> ~/.zshrc # add autocomplete permanently to your zsh shell
