How to execute IRIS restart from inside

Some changes in IRIS configuration require a restart of IRIS.
This is no big issue as long as I have access to the server command line with sufficient privileges.

In a container, this is not always given.
Stopping IRIS from the terminal/session prompt is no problem.
But the restart after is.  

Note1: container start-stop is no option as it might be removed by option --rm in docker run
Note2: the target is linux (manly in docker).  Windows is excluded

To be able to restart IRIS from inside, you in any way will need some independent process on the OS level outside of IRIS, which will control stopping and starting.

If saying about doing it in the container. Most of the changes which would need to restart it, have to be prepared in Docker build process, so, it should be as part of the base image.

Docker supports command to restart, and it's doing it as one command, and it will not delete state during the restart. So, I would say it's a preferable way.
