I tried just create the entrypoint.sh file inside of Dockerfile with:

RUN echo "#!/bin/bash" \
"set -e" \
"export PATH=~/bin:${GEM_HOME}/bin:${PATH}" \
"rm -f ~/pids/server.pid" \
"exec "$"" > /var/lib/docker/tmp/docker-builder771789171/extras/containers/entrypoint.sh@

using the file that I found on the server:

"/var/lib/docker/overlay2/6ca835493bbf80cd43e3d65bf15b9768533fb7b22b9c026a8050588fcd66874d/diff/usr/src/app/extras/containers/entrypoint.sh"

without result.

Yup, I was trying with the docker-compose from github.
https://github.com/theforeman/foreman/blob/develop/docker-compose.yml

can you confirm it works with the images published at quay.io instead of building it yourself?

Also can't run it.

Details:

I'm a bit confused, a couple of items:

- you are not suppose to run it as a single container, you need additional services such as db, redis etc, its meant to either running using docker-compose or kubernetes (I maintain a version that I use at https://github.com/ohadlevy/foreman-kube/)
- you are rebuilding the published images, did you try to do docker-compose pull or are you building it with a different plugin combinations (see https://github.com/theforeman/foreman/blob/develop/developer_docs/containers.asciidoc for more usage details).
