1. List available contexts to check if the desired context exists:

kubectl config get-contexts 

2. Select the context you wish to use. For example, to use docker-desktop, run:

kubectl config use-context docker-desktop 

3. Verify the active context. The output should display docker-desktop:

kubectl config current-context

[Optional] Unset the KUBECONFIG variable if needed:

If you've set the KUBECONFIG environment variable manually (e.g., pointing to a specific file), you can unset it to revert to the default kubeconfig:
