A simple kubectl context switcher cli tool

contswi - Kubernetes Context Switcher

contswi is a simple but effective command-line tool designed for Linux environments to quickly switch between different Kubernetes contexts. By leveraging kubectl, this tool allows users to select and change their active context using an intuitive menu-driven interface, navigable with arrow keys.

Features

• Quickly view all available Kubernetes contexts.
• Highlight the current active context.
• Easily switch between contexts using an interactive, arrow-key driven menu.
• Clean, responsive, and simple interface that fits into any Kubernetes workflow.

Requirements

Before using contswi, ensure you have the following set up:

1. kubectl: The Kubernetes command-line tool must be installed and properly configured on your system. This application interacts directly with kubectl to retrieve and set contexts.

   • Installation guide: kubectl official documentation

2. Pre-configured Kubernetes Contexts: You must have one or more Kubernetes contexts already set up in your kubeconfig. If you don't have any contexts configured, refer to the Kubernetes context documentation to set them up.

Installation

1. Clone the repository:

   git clone https://github.com/yourusername/contswi.git
   cd contswi
   

2. Install the tool via pip:

   After you have cloned the repository, you can install the tool locally:

   pip install .
   

Usage

Once installed, you can use the contswi tool to interactively switch Kubernetes contexts.

Run the tool

contswi

Key Bindings

• Up Arrow (↑): Move the selection upwards.
• Down Arrow (↓): Move the selection downwards.
• Enter: Select the highlighted context and switch to it.
• Ctrl+C: Exit the program at any time.

Example

1. Running contswi will present a list of your Kubernetes contexts:

     dev-cluster  
   > prod-cluster <  
     staging-cluster  
   

2. Use the arrow keys to navigate through the contexts and press Enter to switch.

3. The tool will execute the equivalent of:

   kubectl config use-context <selected_context>
   

4. You will see the selected context become the active one.

Error Handling

If you encounter any errors or issues with the program (e.g., no configured contexts), the tool will handle it gracefully, providing helpful error messages.
