Phusion Docker image vs standard linux image

[felipeZ]

As far as I understand there are mainly 3 reason to use a phusion image instead of a standard linux image (or python image):

• You need to run multiple processes. Even though Docker recommends a single application per container.
• You need the cron command.
• You want to connect to the container through a SSH protocol. In other words, do we have any procedure that we can not handle using docker exec ?

Here is an interesting discussion about SSH in docker

37 uses the default python docker images and ssh is disabled in the images.
