How to Set Up a Permanent Alias for microk8s kubectl for Easier Kubernetes Management

When managing a Kubernetes cluster with MicroK8s, you often need to run microk8s kubectl commands to interact with your Kubernetes resources. If you’re using MicroK8s regularly, typing microk8s kubectl can become repetitive, especially if you’re running multiple commands.

A simple solution to this problem is to set up an alias that will allow you to use kubectl (or any custom name) as a shortcut for microk8s kubectl. In this blog, we’ll show you how to set up a permanent alias for microk8s kubectl to streamline your workflow.

Step 1: Open Your Shell Configuration File

Aliases can be set in your shell’s configuration file. This file is loaded each time you open a new terminal session, making the alias permanent.

For Bash:

If you’re using Bash as your shell, you need to edit the .bashrc file located in your home directory.

nano ~/.bashrc

For Zsh:

If you’re using Zsh as your shell, you need to edit the .zshrc file.

nano ~/.zshrc

Step 2: Add the Alias for microk8s kubectl

Once the configuration file is open, you can add your alias. You can choose to use the default kubectl command, or you can create a custom name for the alias.

Example 1: Alias for microk8s kubectl (using kubectl as the alias)

Add the following line to the file:

alias kubectl="microk8s kubectl"

Example 2: Alias with a Custom Name (e.g., mkubectl)

If you prefer a custom alias, you can use a different name like mkubectl:

alias mkubectl="microk8s kubectl"

You can choose any name that makes sense for your workflow.

Step 3: Save the File and Apply the Changes

After adding the alias, save and exit the file.

  • In Nano, press Ctrl + X, then press Y to confirm, followed by Enter to save the changes.

Next, you need to reload your shell configuration file to apply the changes immediately.

  • For Bash, run: source ~/.bashrc
  • For Zsh, run: source ~/.zshrc

Step 4: Test the Alias

Now that you’ve added the alias, you can test it by running a Kubernetes command. If you chose to use kubectl as the alias, you can run:

kubectl get pods

This command will execute microk8s kubectl get pods, allowing you to interact with your Kubernetes cluster with the shorter alias.

If you used a custom alias like mkubectl, just run:

mkubectl get pods

The result will be the same, but with a different alias for convenience.

Why Use Aliases for microk8s kubectl?

Setting up an alias for microk8s kubectl can improve your productivity in several ways:

  1. Faster Workflow: Typing kubectl or a custom alias is much quicker than typing microk8s kubectl each time.
  2. Consistency: If you’re familiar with kubectl from using other Kubernetes environments, the alias provides consistency in your commands.
  3. Error Reduction: A single command will reduce the chance of misspelling or mistakenly typing out the longer microk8s kubectl.

Conclusion

By setting up a permanent alias for microk8s kubectl, you streamline your workflow and save time when managing your MicroK8s cluster. Whether you prefer the default kubectl or want to use a custom alias, this simple trick can make your Kubernetes management smoother and more efficient.
