​
Goal

Understand templates as a managed service-deployment layer on top of stacks.

​
Prerequisites

  • Understand stacks

​
Workflow

1
Treat templates as a deployment product, not a separate runtime.
2
Expect template-backed stacks to preserve version and input history.
3
Use template lifecycle tooling to preview and apply updates safely.

​
Why templates exist

Templates make common services easier to deploy and maintain by pairing a stack blueprint with defaults, service notes, lifecycle metadata, and safer update behavior.

​
What templates add on top of stacks

  • Saved deployment inputs and secret handling
  • Version tracking and upgrade previews
  • Readiness notes, operator guidance, and safer update paths

​
Expected result

You can explain why templates are different from pasting raw Compose into a stack.
