Install jobber inside non-alpine docker

[nikoshkus]

Hello,
I've tried to install jobber binary inside docker with :
FROM php:7.4.0-apache
RUN wget -q https://github.com/dshearer/jobber/releases/download/v1.4.4/jobber_1.4.4-1_amd64.deb && /usr/bin/dpkg -i jobber_1.4.4-1_amd64.deb
and got this:
Unpacking jobber (1.4.4-1) ...
Setting up jobber (1.4.4-1) ...
invoke-rc.d: could not determine current runlevel
invoke-rc.d: policy-rc.d denied execution of start.

If I try to init jobber inside docker:
Jobber doesn't seem to be running for user root.
(No socket at /var/jobber/0/cmd.sock.): stat /var/jobber/0/cmd.sock: no such file or directory

How does it can be resolved?

This is a bit tricky. Jobber needs to run several daemons, and that is not really possible in Docker. How are you trying to use Jobber in this image?

This should work also with other distributions:

Dockerfile

this worked for me on ubuntu 20.04
