Docker multiple entrypoints

Question

Say I have the following Dockerfile:

FROM ubuntu

RUN apt-get update
RUN apt-get install -y apache2
RUN apt-get install -y mongod #pretend this exists

EXPOS         


        

Answer 1

My solution is to throw individual scripts into /opt/run/ and execute them with:

#!/bin/bash

LOG=/var/log/all

touch $LOG

for a in /opt/run/*
do
    $a >> $LOG &
done

tail -f $LOG

And my entry point is just the location of this script, say it's called /opt/bin/run_all:

ADD 00_sshd /opt/run/
ADD 01_nginx /opt/run/

ADD run_all /opt/bin/
ENTRYPOINT ["/opt/bin/run_all"]
