combined docker images

[georgir]

It would be really awesome if instead of (or in addition to) separate image for each language there was an image that had all (or at least any two) languages at the same time, so you can run scenarios that require interaction between the two languages
(use-case I'm thinking of is multiplayer puzzles where each player is free to use their own language)

From a superficial googling on the topic, it seems literally combining docker images is not possible.
Maybe the easiest approach then would be to have a "docker controller" pseudo-language that is just bash but with read access to all other docker images, so it can run them in turn, potentially piping their stdio as appropriate or even setting up named pipes or whatever else control mechanism the user desires.

You can simply install multiple compilers in the same docker image.
