kubectl Rollout

• Manage the rollout of a daemonset, deployment or statefulset resource.

status

# Check the rollout status of a resource
kubectl rollout status deployment "foo"
kubectl rollout status daemonset "foo"
kubectl rollout status statefulset "foo"

history

# Show revisions history (records last 10 by default)
kubectl rollout history deployment "foo"

# Show a specific revision
kubectl rollout history deployment "foo" --revision=1

restart

• Restarts the current revision

kubectl rollout restart deployment # from all deployments
kubectl rollout restart deployment "foo" # from specific deployment
kubectl rollout restart -f "manifest.yaml" # from manifest

pause

• Pause the deployment controller so that no pods are rolled out
• It's useful when you want to perform multiple imperative commands and resume only after all of them have been executed
• While a deployment is paused, the changes do not appear in the rollout history. The revision is created only when it is unpaused and as a single revision (even if multiple edits have been made)

kubectl rollout pause deployment "foo"

resume

• Resume deployment controlling

kubectl rollout resume deployment "foo"

undo

• When a rollback is made to a specific revision, this revision is bubbled up to the last revision
• Example: Given the revisions Rev1, Rev2, Rev3 when rolling out to Rev2 it goes to the last revision as a new one Rev1, Rev3, Rev4

# Rollback to the previous revision
kubectl rollout undo deployment "foo"

# Rollback to specific revision
kubectl rollout undo deployment "foo" --to-revision "3"
