We started using Docker in pebble mostly on our development server running things like Jenkins. More recently we are using it as part of the development process. This is a quick talk to introduce you to docker and give a high level introduction how it can be used.

1. Continuous Integration and Deployment

2. Ship it!
Editing files on server
FTP
Capistrano
git push

3. Dev to deployment pipeline
Hack
Run local tests
git push
CI server runs tests
Deploy

4. Oops.. 500 Server Error

5. Not my problem.

6. UNIX is case sensitive, OSX is not
Different versions of packages
Different versions of runtimes
Permissions problems
Network problems
Simple things can go wrong

7. Containers

8. Linux Containers (LXC)
Shares Kernel on Host Machine
via cgroups can limit CPU, memory, block I/O,
network
Fast to boot

9. Using LXC

10. Hello Docker
docker run -d -p 80:80 tutum/wordpress

11. Docker love-in
Amazon
Digital Ocean
Rackspace
Linode
Microsoft

12. Run anywhere
Less vendor lock-in
Drives competition
Strong consistency
True DevOps

13. Docker use cases
Testing (SOA, microservices)
Short lived computation environments
Long lived application environments
Software experimentation (Docker Hub)

14. Deployment pipeline
git push
CI Server builds docker image
Run tests inside docker image
CI Server pushes to private Docker Hub
CI Server notifies Elastic Beanstalk
Elastic Beanstalk pulls new image and runs it

15. Everyone is happy

16. UNIX Beard
Environment consistency
Security
Can create base images
Control via Dockerfile

17. Hipster Developer
git push deployment
I AM DEVOPS
Removes environment hell
Can focus on code

18. Client
AWESOME!
I have a meeting now.

19. Thanks!
