15. Dockerfile FROM ubuntu:16.10 RUN apt-get update RUN apt-get install x y z CMD java
16. Docker Image $ docker build -t acme/jira:7.0 .
17. Docker Images $ docker images REPOSITORY TAG IMAGE ID CREATED SIZE elixir 1.3 b80c8e9d71f9 3 weeks ago 758.7 MB acme/jira 7.0 e552540688e1 4 weeks ago 224.4 MB alpine 3.4 ee4603260daa 4 weeks ago 4.803 MB
18. Docker Container $ docker run acme/jira:7.0
19. Orchestration With Docker Swarm Mode
20. Swarm Mode ≇ Swarm
21. Vocabulary • Node • Manager • Worker • Service
22. Creating a Swarm $ docker swarm init
23. Joining a Swarm $ docker swarm join --token xxxx 192.168.66.100:2377
24. Creating a Service $ docker service create --name jira acme/jira:7.0
25. Creating Services $ docker service create --name crowd acme/crowd:2.10 $ docker service create --name jira acme/jira:7.0 $ docker service create --name confl.. acme/confluence:5.10
26. Scaling

28. Service Discovery
29. Scaling a Service $ wget http://jira:8080 $ wget http://confluence:8081
30. Oh yeah, and you get load balancing for free ...
31. Upgrading
32. Scaling a Service $ docker service update --image acme/jira:10.1 jira
33. Potential Problems
34. Configuration
35. Configuration $ docker service create --env DB_HOST=postgres $ docker service update --env-add DB_HOST=postgres
36. Persistence
37. Persistence $ docker service create --mount \ type=mount, source=/mnt/volume, destination=/path/in/container
38. ⚖ How can I scale this?
39. Scaling the Persistence NFS / Fuse mount on all nodes Feeling fancy? Check out CernVM-FS!
40. This brings other problems
41. With the Atlassian Suite You can deal with it, as most writes to the disk are simply cache! Except BitBucket
42. Official Support?
43. ⏳ It’s being worked on…
44. Atlassian on Docker Hub https://hub.docker.com/r/atlassian/
