I have a dockerfile that I'm creating for a project. I've tried to update the ENTRYPOINT to my shell script but I don't see it in the docker inspect readout. My docker-entrypoint.sh permission is denying the container from running.

Dockerfile:

FROM mongo

USER root

# Workdir configs directory
WORKDIR /usr/src/configs

#Install app dependencies
COPY replicaSet.js .
COPY setup.sh .

ENTRYPOINT ["setup.sh"]

CMD ["chmod", "+x", "/usr/src/configs/setup.sh"]

Dockerfile inspected:

I am expecting the container to run without denying permission. I've attempted to run with "chmod +x" with my script with no luck, and it seemed like ENTRYPOINT had been working for most users

  • In brief, the combination you are trying does not do anything useful. You want to put the `chmod` in a regular `RUN` statement and probably leave the `ENTRYPOINT` alone; thus move what you have there into `CMD` instead. – tripleee May 03 '23 at 06:45
  • [Given how long your other question has languished in the Staging Ground](https://stackoverflow.com/staging-ground/76154858) perhaps spend more time on learning how this site works before posting more questions. – tripleee May 03 '23 at 06:45
  • That link doesn't work for me, @tripleee, maybe it requires additional privileges. – Ulrich Eckhardt May 03 '23 at 06:55
  • @UlrichEckhardt Yeah, Staging Ground is still in beta and requires you to be in the beta group. – tripleee May 03 '23 at 07:25

When you have both an ENTRYPOINT and a CMD statement, they're combined at run-time to a single command with the CMD as parameters for the ENTRYPOINT.

In your case, the command becomes

setup.sh chmod +x /usr/src/configs/setup.sh

That's probably not what you want.

You can change the permissions on the script in a RUN statement, so it's done at build time instead, like this

FROM mongo

USER root

# Workdir configs directory
WORKDIR /usr/src/configs

#Install app dependencies
COPY replicaSet.js .
COPY setup.sh .
RUN chmod +x setup.sh

ENTRYPOINT ["setup.sh"]
