kubectx is a great tool for Kubernetes that provides a kubectx and kubens command that make it easier for you to work with multiple clusters and namespaces.

kubectx-zshplugin automatically installs them into your ZSH environment for you.

kubectx-zshplugin can be automatically loaded as a ZSH plugin by any framework that supports oh-my-zsh compatible plugins.

If you're using zgen:

1. Add zgen load unixorn/kubectx-zshplugin to your .zshrc along with your other zgen load commands.
2. zgen reset && zgen save. zgen will automatically clone the git repository the next time you start a terminal session.

If you're using Antigen:

1. Add antigen bundle unixorn/kubectx-zshplugin to your .zshrc where you've listed your other plugins.
2. Close and reopen your terminal window to start a new session and Antigen will automatically clone and load the plugin for you. Alternatively, you can run antigen bundle unixorn/kubectx-zshplugin in a running shell to have antigen automatically clone and load the new plugin immediately.

If you're using oh-my-zsh:

1. In the terminal, change to oh-my-zsh's custom plugin directory:

   cd ~/.oh-my-zsh/custom/plugins/

2. Clone the repository into a new kubectx directory:

   git clone --recursive https://github.com/unixorn/kubectx-zshplugin.git kubectx
   cd ~/.oh-my-zsh/custom/plugins/kubectx/
   git submodule init
   git submodule update
   

3. Edit your ~/.zshrc and add kubectx – same as clone directory – to the list of plugins to enable:

   plugins=( ... kubectx )

4. Then, restart your terminal application to refresh context and use the plugin. Alternatively, you can source your current shell configuration:

   source ~/.zshrc
