To use the kubectl config command, follow these steps:

1. Install kubectl: If you haven’t already, install kubectl on your machine. You can find installation instructions for your operating system on the Kubernetes documentation website.

2. View the current context: To see the current context, which represents the cluster, user, and namespace that kubectl is currently configured to use, run the following command:

   kubectl config current-context
   

3. View the available contexts: To see a list of available contexts, which represent different Kubernetes clusters, users, and namespaces that kubectl can be configured to use, run the following command:

   kubectl config get-contexts
   

4. Switch the active context: To switch to a different context, use the use-context subcommand followed by the name of the context. For example, if you have a context named “my-cluster”, run the following command to switch to that context:

   kubectl config use-context my-cluster
   

5. Set the default namespace: If you want to set a default namespace for kubectl to use, you can use the set-context subcommand. For example, to set the default namespace to “my-namespace”, run the following command:

   kubectl config set-context --current --namespace=my-namespace
   

6. View and edit configuration files: The kubectl config command also allows you to view and edit the configuration files used by kubectl. The configuration files are typically located in the ~/.kube directory. You can view the current configuration file by running:

   kubectl config view
   

   To edit the configuration file, you can use a text editor to modify the file directly.

That’s it! You have now used the kubectl config command to view and manage the configuration for kubectl.
