Keeping up with the latest updates and features of Kubernetes is essential for maintaining a secure and efficient container orchestration environment. Knowing your Kubernetes version helps you stay on top of any necessary upgrades and understand the compatibility of your cluster with various tools and resources. In this guide, we’ll walk you through the process of checking your Kubernetes version with ease. So, let’s get started!
1. Checking Kubernetes Version Using kubectl
To check your Kubernetes version, you’ll need to use the kubectl command-line tool. If you haven’t installed kubectl yet, head over to the official Kubernetes documentation for installation instructions.
Once you have kubectl installed, open your terminal or command prompt and run the following command:
kubectl version --short
This command returns both the client and server versions of your Kubernetes cluster. The output should look something like this:
Client Version: v1.22.0 Server Version: v1.21.3
The client version represents the kubectl tool version, while the server version indicates the Kubernetes cluster’s version.
2. Checking Kubernetes Version Directly on the Cluster
If you’re running a Kubernetes cluster on a cloud provider or on-premises, you might want to check the version directly on the cluster nodes. To do this, you can use the following command:
kubelet --version
This command returns the kubelet version installed on the node, which should be the same as the Kubernetes version. The output will resemble:
Kubernetes v1.21.3
3. Using the Kubernetes Dashboard
The Kubernetes Dashboard is a user-friendly web-based interface for managing your Kubernetes cluster. If you have the dashboard installed, you can check the Kubernetes version by navigating to the “Cluster” section and locating the version information under the “Overview” tab.
4. Upgrading Your Kubernetes Version
Staying up-to-date with the latest Kubernetes version is crucial for security, stability, and access to new features. To upgrade your Kubernetes cluster, follow our comprehensive guide on Kubernetes Cluster Upgrades.
