The document is a presentation about using Docker Compose for development and testing environments, featuring examples like an identity service and browser tests. It emphasizes the flexibility of Docker tools beyond just development and testing, hinting at their application in production as well. The agenda includes opening remarks, examples, and time for questions.

2. The Agenda
• Opening remarks
• Two super fun examples:
• Service dependencies (An identity service)
• Test services (Browser tests)
• Closing remarks
• Questions

3. Opening Remarks
• This presentation focuses on dev/test use cases,
but it’s simple to deploy Docker images to
production from CircleCI too!
(see circleci.com/docs/docker)
• Remember these are examples, think about how
the same tools can help you.
(e.g. maybe you care about compilers or linters
instead of browser tests)
