Kubectl Rollout Strategy
Zero-downtime deploys: history, pause, resume, and rollback.
Commands
| Command | What it does |
|---|---|
kubectl rollout history deploy/api | Revision list |
kubectl rollout status deploy/api | Block until rollout finishes |
kubectl rollout pause deploy/api | Canary: stop after first new pods |
kubectl rollout resume deploy/api | Continue a paused rollout |
kubectl rollout restart deploy/api | Fresh pods, same image (e.g. reload secrets) |
Example
kubectl set image deploy/api api=registry/api:v2
kubectl rollout status deploy/api
kubectl rollout undo deploy/api --to-revision=3FAQ
How do canary releases work here?
Pause mid-rollout, verify metrics on new pods, then resume — or use Argo Rollouts for real weighted canaries.
rollout restart — when?
After Secret/ConfigMap changes or to clear leaked state without changing the image tag.
