Bitbucket CI not running my script within the step when using a custom docker container


We have a custom docker container we are using for testing and building, but the script in the first step its not executing, it just tells me that it did the build setup and build teardown but nothing else... I tried so set a workdir (/root) in the container, put most apt commands in one RUN command but to no avail, 

What baffles me the most is that all other containers run fine and execute the steps properly like the google sdk alpine image

The parts that failing in our bitbucket-pipelines.yml

- step:
name: Install Dependencies
- composer install
- composer
- vendor

- step:
name: Test
- /vendor/bin/phpunit
- composer
- vendor 

This is our current test container setup

FROM ubuntu:20.04

Hi Tigo and welcome to the community!

I've built a Docker image based on the Dockerfile you posted here and I see the same issue. The issue gets resolved if I remove the following line from the Dockerfile:

USER nobody

So, this seems to be the culprit, I suspect because Pipelines by default runs as root.

Are you able to use the image if you remove that from the Dockerfile?

Kind regards,

Thank you for your suggestion!


It was indeed the problem...



You are very welcome, I'm glad to have helped.
