kubech (kubectl change)

Set kubectl contexts/namespaces per shell/terminal to manage multi Kubernetes cluster at the same time.

i.e. same as kubectx/kubens but per shell/terminal.

Why

If you manage multi K8s clusters, you will need a handy way to work more than one cluster at the same time.
kubectx/kubens tools fix this problem but globally, that means all shells and terminals will have the same context/namespace.
However, this is not helpful at all if you are actually working with multi clusters at the same time.
Thus, kubech comes to fix this problem so you can set K8s cluster context/namespace per shell/terminal.

Features

Each shell/terminal will have its own context (K8s cluster) or namespace!
Easy to use! Just source it in your favorite shell.
No aliases, no extra customizations, it doesn't matter if you work with 1 or 100 K8s clusters!
It still can be used along with other tools like kubectx/kubens.
It doesn't change anything in ~/.kube/config file. So it works perfectly with static and dynamic kube config files.
It supports autocomplete for contexts and namespaces.

Install

Clone this repo, then source kubech in your shell config file.

git clone https://github.com/aabouzaid/kubech ~/.kubech

Bash

echo 'source ~/.kubech/kubech' >> ~/.bashrc
echo 'source ~/.kubech/completion/kubech.bash' >> ~/.bashrc

Usage

NOTE:
  - The command "kubech" is just a meta for other commands. So kubech does nothing by itself.
  - Short names "kchc/kchn" are also available.

USAGE:
  kubechc             : List all contexts
  kubechc <CONTEXT>   : Switch to context <CONTEXT>
  kubechn             : List all namespaces
  kubechn <NAMESPACE> : Switch to namespace <NAMESPACE>

List available contexts

$ kubechc
k8s_cluster01
k8s_cluster02

Switch context

No need to write the full name, press tab for auto complete.

$ kubechc k8s_cluster01

List available namespaces

$ kubechn
default
kube-public
kube-system
monitoring

Switch namespace
