This is my story about how I got involved in the Docker hackathon (and won) without knowing Docker at all. I'll share what technological limitations I had before using Docker and how I managed to solve them, and also some tips to getting started. As a closing, I'll talk about the Whaleprint project and some key features that we would love to see in docker today.

2. From Zero Docker
to Hackathon
Winner

3. As many young projects do, I faced these most common
problems:
• Consistent development environments.
• On boarding team members.
• Shipping code from development to production.
Before Docker and I met

4. • Docker Documentation - [ https://docs.docker.com/ ]
• Docker Training - [ https://training.docker.com/ ]
• PWD: Interactive tutorials - [ http://training.play-with-docker.com/ ]
Leveling up my zero Docker
There is a lot of information on the web, but do not panic!
Just start with the official documentation and grow from there.
Watch out for third-party content as it might contain outdated or hacky
workarounds for things that are clearly explained in the official docs.

5. Willing to
participate in
Docker hackathon
but no project to
do so.
Aha moment!
Messing around
with Docker
Training examples
about Docker
Swarm.

Marcos

6. Allow users to
manage DAB files as
service blueprints, in
order to understand
what will happen with
incoming changes.
The idea

7. OMG…
here I go!

8. Hacking process
• Usability / UX.
• Testing.
• Docker source code.
• Coding.
We distributed tasks among the team:

9. Whaleprint
Sketch

10. Other features
• Export current Swarm configuration.
• Output service’s public ports.
• Destroy swarm services as needed.
• Manage multiple stacks at once.

11. ~ docker-compose_memcached
.TaskTemplate.ContainerSpec.Image: "memcached:3.1" => "memcached"
.Mode.Replicated.Replicas: "1" => "2"
+ docker-compose_nginx
.Annotations.Name: "docker-compose_nginx"
.TaskTemplate.ContainerSpec.Image: "nginx:1.11.6-alpine"
.Mode.Replicated.Replicas: "1"
.EndpointSpec.Mode: "vip"
We’ve got our MVP !

12. And so results arrived
YOU WON !

13. - Focus on MVP.
- Take into account who the users of
your product will be.
- Keep it understandable, easily
configurable, self-explained and
well documented.
- Docker source code does not bite!
- Keep calm and have fun while
hacking!
Hackathon -
Lessons learned

14. Short Demo
