I am trying to build a mongo 4.4 image based on the official image Dockerfile but I am running into an issue with systemctl not found. The image itself has a line to remove it after setup, but not sure where it came from. Any ideas?

To be precise

RUN ln -s /bin/echo /bin/systemctl
RUN apt-get -qqy install  mongodb-org

FL3SH answer works but to convey the meaning more effectively you can create a symbolic link from /bin/systemctl to /bin/true.

/bin/true is a command wich always return 0 (the truthy value of the shell) so it does not fail. It's a standard way to indicate that you want to return true. See this SO post also

The command you need to add in the Dockerfile is:

RUN ln -s /bin/true /usr/local/bin/systemctl

or

RUN ln -s /bin/true /bin/systemctl

The effect is that you trick the post-install script by calling /bin/true instead of /bin/systemctl

You can find the same trick into the official mongodb Dockerfile 4.4 line 91 that haytham linked in his description.

/bin/echo works as well as /bin/true because echo returns 0 as well. You can try it by doing

echo "test"
echo $?

And you'll see 0 as the result of the second echo.

echo ln to /bin/systemctl solves the issue.
