fubectl

Because it's fancy-kubectl !

Prerequisites?

• fzf
• kubectl

• jq

Installation

You can directly download the fubectl.source and save it in some directory.

Download:

curl -LO https://raw.githubusercontent.com/kubermatic/fubectl/refs/heads/main/fubectl.source

then add to your .bashrc/.zshrc file:

[ -f <path-to>/fubectl.source ] && source <path-to>/fubectl.source

Alternatively you can install fubectl using the ZSH plugin manager of your choice.

Extra!

Do you want to have the current kubecontext in your prompt?:

export PS1="\[$(kubectxname)\] $PS1"

for the current namespace (this is currently slow, because it calls kubectl every time):

export PS1="\[$(kubectxnamespace)\] $PS1"

Customization

fubectl can be customized via following environment variables

• FUBECTLWATCHCMD – alterative watch command, e.g. viddy
• FUBECTLNOKCL – disable kcl alias, since it may conflict with KCL language CLI
