Kubernetes Fundamentals: From Container to Cluster
Take the containers you learned to run with Docker and orchestrate them across a real Kubernetes cluster - Pods, Deployments, Services, ConfigMaps, and the reconcile loop - all through declarative YAML and kubectl.
// What you'll be able to do- Prerequisites, cost, and honest expectations
- Spin up a local cluster and verify kubectl
- The smallest deployable unit and how desired state is enforced
- ReplicaSets, rolling updates, and rollbacks
