kubectl-aliases

This repository contains a script to generate hundreds of convenient shell aliases for kubectl, so you no longer need to spell out every single command and --flag over and over again.

An example shell alias created from command/flags permutation looks like:

alias ksysgdepwslowidel='kubectl --namespace=kube-system get deployment --watch --show-labels -o=wide -l'

Confused? Read on.

Examples

Some of the 800 generated aliases are:

alias k='kubectl'
alias kg='kubectl get'
alias kgpo='kubectl get pod'

alias ksysgpo='kubectl --namespace=kube-system get pod'

alias krm='kubectl delete'
alias krmf='kubectl delete -f'
alias krming='kubectl delete ingress'
alias krmingl='kubectl delete ingress -l'
alias krmingall='kubectl delete ingress --all-namespaces'

alias kgsvcoyaml='kubectl get service -o=yaml'
alias kgsvcwn='watch kubectl get service --namespace'
alias kgsvcslwn='watch kubectl get service --show-labels --namespace'

alias kgwf='watch kubectl get -f'
...

See the full list.

Installation

You can directly download the .kubectl_aliases file and save it in your $HOME directory, then edit your .bashrc/.zshrc file with:

[ -f ~/.kubectl_aliases ] && source ~/.kubectl_aliases

Recommendation: If you want to use GNU watch command instead of kubectl [...] --watch, run it like this:

[ -f ~/.kubectl_aliases ] && source \
   <(cat ~/.kubectl_aliases | sed -r 's/(kubectl.*) --watch/watch \1/g')

Print the full command before running it: Add this to your .bashrc or .zshrc file:

function kubectl() { echo "+ kubectl $@">&2; command kubectl $@; }

FAQ

  • Doesn't this slow down my shell start up? Sourcing the file that contains ~500 aliases takes about 30-45 milliseconds in my shell (zsh). I don't think it's a big deal for me. Measure it with echo $(($(date +%s%N)/1000000)) command yourself in your .bashrc/.zshrc.

  • Can I add more Kubernetes resource types to this? Please consider forking this repo and adding the resource types you want. Not all resource types are used by everyone, and adding more resource types slows down shell initialization see above).

  • Where can I find PowerShell aliases for kubectl? There’s a fork of this here.
