Kubernetes has become the go-to platform for managing containerized applications, and at the heart of managing a Kubernetes cluster is Kubectl. Kubectl is the command-line tool that allows you to interact with your Kubernetes cluster, making it essential for tasks like deploying applications, monitoring cluster health, and managing resources. If you’re working with Kubernetes, Kubectl is a must-have.
In this article, we’ll give you a quick overview of the process to install Kubectl on Ubuntu 22.04 and discuss why this tool is so crucial for anyone working with Kubernetes.
