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 to run the commands I want.
The question is, is it possible to run multiple commands with ENTRYPOINT?
Or should I create a small bash script to start all?
Basically what I would like to do is:
ENTRYPOINT /opt/pivotal/webserver/instance1/bin/httpdctl start && /opt/pivotal/webserver/instance2/bin/httpdctl start && /opt/pivotal/pivotal-tc-server-standard/ start instance1 -i /opt/pivotal/pivotal-tc-server-standard && /opt/pivotal/pivotal-tc-server-standard/ start instance2 -i /opt/pivotal/pivotal-tc-server-standard
But I don't know if that is a good practice or if that would even work.

In case you want to run many commands at entrypoint, the best idea is to create a 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 commands 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
You can use something like this:
ENTRYPOINT ["/bin/sh", "-c" , "<command A> && <command B> && <command C>"]
You can use npm concurrently package.
For e.g.
ENTRYPOINT ["npx","concurrently","command1","command2"]
It will run them in parallel.
