11. Few ps before start
    Use some service to run containers
    eg. ECS, Docker Cloud, ...
    Use same image for development and production
    Don't mount code to containers in production
    If you need logs, send them from container
    Don't run databases in containers until you know what you're doing
    (you may loose all your data)
    Automate in small steps, not everything at once
