But then you have many more docker images for different kinds of services that you all have to rebuild, no? Or do you just have one docker image?

And out of curiosity: is your testing of new images automated?

We have many images, and we build them in a CI setup using jenkins. I used to run jenkins inside docker and build images within that docker, but this turned out to be a problem. (Mainly more and more resources were used up until the disk was full.) Now it's just jenkins installed on the host building images, starting them and run integration tests.
