In this lesson: Kubernetes pods, deployments, services, ConfigMaps, Secrets, and volumes, Docker Swarm services and stacks, Docker and Podman Compose (up, down, logs), and when to use which, with Pinecrest Media, a fictional video streaming company, as the running example. Includes three original practice questions.

- A developer must start the catalog, its database, and a cache on one laptop, with a single command and one file kept in the repository. Which tool fits?
