• Spring Framework
• RabbitMQ
• Concourse
• Cloud Foundry
• Pivotal Tracker
• Gemfire

4. Agenda
• Concourse
• Docker Compose
• Demo
• Q&A

5. Concourse

6. Concourse
• Pluggable Resource Interface
• Running builds in Containers Natively
• Zero Snowflake-able Configuration
• Submitting builds from the local file system up to run in CI
• Pipeline pipeline pipeline !!!
• Reproducible

7. Concourse

8. Concourse but …
• No core support for service
• No docker daemon
• Only support external resource

9. External service
Concourse
Garden
External

10. • Running service (databases) to test against
• Avoiding snowflakes
• Strict isolation between job
• Some caching
Wanted

12. DCIND* ?
Docker in Docker ?

13. DCIND* ?
Docker in Docker ?

14. DCINDING* ?
Docker in Docker in Garden ?

15. Docker in Docker in Garden
• Just one solution example
• Works :)
• Generic
• More than one service Redis + MySql + ….
• One file to setup

16. Worker Workers

20. Concourse
• Jobs
• Resource
} PIPELINE
• Task

21. Task testing.yml
Docker image dcind
Start Docker daemon
use cached image
run compose app

22. Docker Compose docker-compose.yml
] Database
Task
Very useful “links”

23. Docker Compose
Links
Links inject environment variable which help for service
discovery for container to container

24. Resource
source code repos
Docker image
to be cached
