I'll venture a guess as to what is happening here, but I don't know for
sure. I guess I could look at the source. ;)
I think what's happening here is that with_sequence is actually invoking a
new module build/upload/run for every item in the with_sequence, and
thereby overwriting the docker_containers variable with the facts from the
last docker module run. So, it's a guess, but you could probably verify
that by running with some extra verbosity (I think you need at least -vv).
This is definitely not happening in the first container launch, because
it's passing those values directly to the module, running only once.
If you don't give it a shot, I'll probably take a look at it in the morning.
Let me know what you find!
