kubectl-cs - Quick Kubernetes context switcher ☸️ 🔄

cs is a kubectl plugin makes it easy to switch between multiple kubeconfig contexts or change the default namespace of the currently selected context.

It's heavily used while working with CloudControl. This is the rewrite in pure go to replace the former bash and gnu-dialog-based tool and turn it into a kubectl plugin.

Requirements

This tool builds upon a locally configured kubeconfig file and the kubectl client.

Installation

Download the binary for your operating system and architecture from the latest kc release and put it somewhere in your path.

Note: Because the tool is not signed, macOS users need to enable execution when starting kc for the first time. To do this, Ctrl-Click on the binary and select "allow".

Usage

Run kubectl cs to switch to a Kubernetes context and/or namespace. You can directly specify the context to switch to in the form of context:namespace. If you leave either of the two parts empty, it will only change the remaining part.

Examples:

• kubectl cs int: - Switch to the currently active namespace in the int context
• kubectl cs :kube-system - Switch to the namespace kube-system in the currently active context
• kubectl cs int:kube-system - Switch to the namespace kube-system in the int context

If you don't specify anything, kubectl cs will present a selection list of all namespaces in all contexts, which can be filtered and selected. If that takes too long, the flag --only-current-context can be used, which only enumerates the namespaces of the current context.
