Workloads I: Deployment & ReplicaSet
A Deployment is the standard way to run stateless applications. A Deployment manages ReplicaSets; a ReplicaSet manages Pods. This two-layer design enables rolling updates: when the Pod template change
Learning objectives
- Explain precisely what a ReplicaSet does that a Deployment delegates to it, versus what the Deployment itself is responsible for.
- Trace exactly how a Deployment's rolling update replaces old Pods with new ones, one batch at a time.
- Perform (and explain) a Deployment rollback, and what it actually reverts to.
