The function must accept a single parameter and echo out the final value. + +### Bug Reports and shell configuration + +Due to the vast ways of customizing the shell, please try the prompt with a +minimal configuration before submitting a bug report. + +This can be done as follows for each shell before loading kube-ps1: + +Bash: +```bash +bash --norc +``` + +Zsh: +```bash +zsh -f +or +zsh --no-rcs +``` + +## Contributors + +* [Ahmet Alp Balkan](https://github.com/ahmetb) +* Jared Yanovich diff --git a/oh-my-zsh/plugins/kube-ps1/kube-ps1.plugin.zsh b/oh-my-zsh/plugins/kube-ps1/kube-ps1.plugin.zsh new file mode 100644 index 0000000..894e0f7 --- /dev/null +++ b/oh-my-zsh/plugins/kube-ps1/kube-ps1.plugin.zsh @@ -0,0 +1,386 @@ +#!/usr/bin/env bash + +# Kubernetes prompt helper for bash/zsh +# Displays current context and namespace + +# Copyright 2021 Jon Mosco +# +# Licensed under the Apache License, Version 2.0 (the "License");
