Multiple commands on docker ENTRYPOINT

Question

I\'m trying to build a custom tcserver docker image. But I\'m having some problems starting the webserver and the tomcat.
As far as I understand I should use ENTRYPOINT

Answer 1

In case you want to run many commands at entrypoint, the best idea is to create an bash file. For example commands.sh like this

#!/bin/bash
mkdir /root/.ssh
echo "Something"
cd tmp
ls
...

And then, in your DockerFile, set entrypoint to commands.sh file (that execute and run all your mands inside)

COPY commands.sh /scripts/commands.sh
RUN ["chmod", "+x", "/scripts/commands.sh"]
ENTRYPOINT ["/scripts/commands.sh"]

After that, each time you start your container. commands.sh will be execute and run all commands that you need. You can take a look here https://github.com/dangminhtruong/drone-chatwork

Answer 2

You can use npm concurrently package.

For e.g.

ENTRYPOINT ["npx","concurrently","command1","command2"]

It will run them in parallel.
