Kubectl Commands

Here are some of the most useful kubectl commands. This is a living list so feel free to suggest commands you find useful.

Get pods sorted by creation time

kubectl get pods --sort-by .metadata.creationTimestamp

Create a simple pod for trouble shooting

Create a base Debian pod that we can install our tools onto.

apiVersion: v1
kind: Pod
metadata:
  name: debian
  namespace: default
spec:
  containers:
  - name: debiantest
    image: debian:latest
    command:
      - sleep
      - "3600"
    imagePullPolicy: IfNotPresent
  restartPolicy: Always

To create the container run the following command.

kubectl create -f https://raw.githubusercontent.com/patrickbeam/useful-kubectl-commands/master/debiantest.yaml

pod/debian created

kubectl get pods debian -n default
NAME     READY   STATUS    RESTARTS   AGE
