by docker-compose
Kengo TODA

3. whoami
Java, JavaScript R&D
Build tools, CI
OSS web app with
distributed dev
environment

4. Merit of Docker
Small, Clean, Quick, Portable, Reproducible
Good for delivery
to cloud, data centre and developer’s machine new!

5. Case: provide dev environment
for your contributors
Web Service needs:
Middleware
Initial data in datastore

6. Legacy ways
to provide dev environment
README.txt
Virtual box, VMware
Vagrant (https://www.vagrantup.com/)

7. Problems of legacy ways

8. Human don’t read
document

9. VM is BIG & SLOW

10. Middleware conflict

11. Docker is
Process to make VM is more clear and documented
Quick bootstrap
Layer is small enough to distribute
Reproducible even on different OS

12. But how to keep
'one service in each container’ policy?

13. docker-compose
Build, run and link containers by one command
Treat set of containers like: Application server, Web
server, Datastore server, Selenium client, build tools…

14. docker-compose.yml

15. docker-compose up
$ docker-compose up
Creating consul_1...
Creating registrator...
Creating storage_1...
Creating front_1...
Creating nginx_1...
Attaching to consul_1, registrator,
storage_1, front_1, nginx_1
consul_1 | ==> Starting raft data
migration...

16. Conclusion
Docker is good for delivery,
even to developers!
