I have previously thought a bit about using something like Supervisor. And if I was running something a bit closer to the metal, with no other infrastructure to restart stuff, then I would be much more pro.

But if inside Docker when something else already has the job of restarting things if they fall over, then it feels a bit over complicated in that there are multiple ways of doing the restarting. Plus, I think there is a touch more visibility - it's all just command line arguments to parallel:

    parallel --will-cite --line-buffer --jobs 2 --halt now,done=1 ::: \
        "some_proc some args" \
        "another_proc some more args"
