So you shouldnt need to rebuild the image with a new challenge (although I dont
 really understand what you are trying to do).

But if I'm thinking correctly, you would restart the container every "x" mins,
that has a new challenge - that is easy to do. (That new challenge is
calculated when the container starts.)

EG: For my BBS containers, I start zerotier if "ZT_ENABLE=1" is set, before
starting the BBS.

Depending on how you start your containers (I use docker swarm):
* If you just "docker run", then you could do "--restart=always", or
"--restart=unless-stopped", and then inside or outside the container kill it.
To kill from inside the container, just "kill 1". From outside the container,
you would do "docker kill <name>",

* If you are using "docker swarm", then the container will auto restart when
you start the stack or service, so "docker stop" or "kill 1" (from inside),
will make it auto restart until you "docker rm service", or "docker rm stack".
