K9S is a command-line interface (CLI) tool that allows you to manage Kubernetes clusters from the terminal. It provides an intuitive user interface and helps you quickly navigate through resources in your cluster.

To install K9S on your Kubernetes cluster, follow the steps below:

Step 1: Download K9S binary

The first step is to download the K9S binary that is compatible with your operating system. You can download the binary from the K9S releases page on GitHub: https://github.com/derailed/k9s/releases

For example, if you are running Linux, you can download the binary by running the following command:

curl -LO https://github.com/derailed/k9s/releases/download/v0.24.9/k9s_Linux_x86_64.tar.gz

This will download the K9S binary to your current directory.

Step 2: Extract the binary

After downloading the binary, extract it using the following command:

tar xvzf k9s_Linux_x86_64.tar.gz

This will extract the K9S binary to a folder named k9s.

Step 3: Move the binary to a location in your PATH

Next, move the K9S binary to a location in your PATH so that you can access it from anywhere in your terminal. You can do this by running the following command:

sudo mv k9s /usr/local/bin/

This will move the K9S binary to the /usr/local/bin directory, which is typically included in the PATH environment variable.

Step 4: Test the installation

To verify that K9S has been installed successfully, run the following command:

k9s version

This should display the version number of K9S that you just installed.

Step 5: Use K9S to manage your Kubernetes cluster

Now that you have installed K9S, you can use it to manage your Kubernetes cluster. To get started, run the following command:

k9s

This will launch the K9S terminal user interface. From here, you can use various commands to manage your Kubernetes resources, such as viewing pods, services, and deployments, as well as creating and deleting resources.

Quick summary

K9S is a powerful tool for managing Kubernetes clusters from the terminal. With its intuitive user interface and rich feature set, it can help you quickly navigate through your cluster and perform common tasks. By following the steps above, you can easily install K9S on your Kubernetes cluster and start using it to manage your resources.
