- 15. You most likely doing it already 15 • Version control • Cover code with tests • nosetests, pytest, unittest2 - start small with doc tests - try out TDD: rednose, nose-watch
- 16. You most likely doing it already 16 • Cover code with tests • yes, even your R application could have tests - testthat - devtools • Code reviews • Pair programming
- 17. Some of the mentioned problems 17 • Many different technologies • Issues with backward compatibility • Dependency hell • Hard to on-board new people
- 21. Some of the mentioned problems 21 • Many different technologies • Issues with backward compatibility • Dependency hell • Hard to on-board new people
- 22. How it could help: 22 • Every technology has its own container - just docker run • Every package with version defined in Dockerfile - have a base image for more advanced cases • New people - just docker run
- 26. Known issues 26 • Images could be really huge • Try to skip anything you do not need • Alpine Linux as a base image • 5 mb base image (musl libc and BusyBox) • Iron.io has pre-built images based on alpine • python, scala, java, elixir, etc

- 28. Some of the mentioned problems 28 • Hard to roll out • Hard to maintain production dependencies
