I have docker container with installed and configured software.
There is no any programm supposed to be started/runned all the time.
What I want - its ability to start some command depending on external events. like:
docker exec mysupercont /path/to/mycommand -bla -for
docker exec mysupercont /path/to/myothercommand
But "exec" impossible when container is stopped, and also this container have some "working" data inside, which used for that commands, so I can't use
docker run ...
each time, because it recreate container from image and destroy my data.
What is the "right" and the "best" way to keep such container runned? Which command I can start inside?
