Cluster Management

kubectl

The kubectl command is used to interact with and manage a Kubernetes cluster. It allows administrators and developers to deploy applications, inspect resources, manage cluster components, and view logs. Essentially, kubectl acts as the command-line interface (CLI) for communicating with the Kubernetes API server to control the state of the cluster.
