Kubectl Cheat Sheet: 60+ Essential Commands for DevOps

This is a task-grouped reference for the kubectl commands you reach for daily.
Bookmark it, then jump to the section you need. Commands use <name> for a
resource name, <ns> for a namespace, and <pod> for a pod name.

Two habits that save time across every section:

• Set a default namespace so you can drop -n <ns> from most commands: kubectl config set-context --current --namespace=<ns>
• Alias k=kubectl and enable shell completion (see the last section).

Keep this page open in a tab during incidents. When you find a command you run
often that is not here, add it to your own dotfiles as an alias so it becomes
muscle memory.
