kubectl-kctx

A minimal kubectl plugin written in Go to reload and inspect your local kubeconfig contexts. This tool is particularly useful for local development environments like kind where you might frequently update your kubeconfig.

Features

• Reload: Fetches and displays the latest contexts from your kubeconfig file.
• List Contexts: Clearly lists all available Kubernetes contexts.
• Validation: Confirms that the kubeconfig is available and loaded correctly.
• Lightweight: Simple and fast, with no external dependencies outside of the standard Go libraries and spf13/cobra.
