generate-dhparam becomes a zombie process

When running a nginx proxy the generation of a dhparam file is executed in the background. However, this causes the process to become a zombie process.

USER       PID %CPU %MEM    VSZ   RSS TTY      STAT START   TIME COMMAND
xxxx     16431  0.0  0.0      0     0 ?        Z    13:07   0:00 [generate-dhpara] <defunct>

My bash knowledge is limited, but I guess this is caused in these lines. Maybe someone with bash knowledge knows how to prevent this.

@frederikbosch OK I tested the better workaround: we upgraded our docker environment to use docker-compose file version 3.7 and docker-engine 18.06 and are able to eliminate zombie processes by specifying init: true ( under nginx service in the yml), without modifying the CMD line.

If you don’t use docker-compose, you should be able to specify docker run --init to achieve the same result

pstree command shows that the forego is now a child of init instead of /bin/sh.
