What is this?
Deployments manage ReplicaSets for declarative rollouts, rollbacks, and replica counts.
Why should you care?
CloudVerse ships new API versions with rolling updates — not delete-all Pods.
See it live — copy this example
Use AWS/Azure/GCP free tier or local Docker/Kind. Sketches and YAML are meant to be typed and adapted.
apiVersion: apps/v1
kind: Deployment
metadata: { name: api }
spec:
replicas: 3
selector: { matchLabels: { app: api } }
template:
metadata: { labels: { app: api } }
spec:
containers:
- name: api
image: cloudverse/api:1.2.0What happened?
- Readiness gates traffic.
- maxUnavailable/maxSurge tune rollouts.
- Rollback with kubectl rollout undo.
Practice next
- Deploy 3 replicas.
- Change image tag.
- rollout status / undo.
- Set maxUnavailable 0.
- Add PodDisruptionBudget.
Remember
Replicas + rollout. Readiness matters. Undo path.
CloudVerse rolling API
v1.2.0 rolls across 3 pods.
Outcome: Zero planned downtime deploy.
