I was not able to get the usage of && to work. I was able to solve this as described here: https://stackoverflow.com/a/19872810/2971199

So in your case you could do:

RUN echo "/usr/sbin/apache2" >> /etc/bash.bashrc
RUN echo "/path/to/mongodb" >> /etc/bash.bashrc
ENTRYPOINT ["/bin/bash"]

You may need/want to edit your start commands.

Be careful if you run your Dockerfile more than once, you probably don't want multiple copies of commands appended to your bash.bashrc file. You could use grep and an if statement to make your RUN command idempotent.
