#concepts

The mental model behind every Docker command: images are read-only templates, containers are running instances of them, and volumes, networks and registries handle data, connectivity and distribution.

The mental model: an event triggers a workflow, the workflow runs jobs on runners, each job runs steps, and steps run shell commands or reusable actions.

The mental model behind every kubectl command: control plane vs nodes, pods, deployments, services, config, storage and namespaces, and how labels tie them together.
