Commands for kubectl, the command line interface of kubernetes

• Get information about current running deployment:

  kubectl get deployment <deploymentName> -o yaml

• Save information about current deployment in a local yaml file:

  kubectl get deployment <deploymentName> -o yaml > currentDeployment.yaml

• Check revisions of a deployment. You can only see the number of histories based on the number set by revisionHistoryLimit in the deployment yaml file.

  kubectl rollout history deployment <deploymentName>

• Roll back to a specific version (let's say 2):

  kubectl rollout undo deployment <deploymentName> --to-revision=2

• Get detailed information about a particular resource e.g. pod named podName:

  kubectl describe pod podName

• Delete everything running. Assuming everything you ran lies in the current folder (e.g. deployment.yaml, replicaset.yaml):

  kubectl delete -f .

• See all available contexts:

  kubectl config get-contexts

• See the current context:

  kubectl config current-context

• Make docker-for-desktop(e.g.) as the current context:

  kubectl config use-context docker-for-desktop
