Any ideas?

Answer 1

That is most likely a Linux file permission issue on config/docker-entrypoint.sh. If your host is Linux/Mac, you can run:
chmod 755 config/docker-entrypoint.sh
For more on linux permissions, here's a helpful article: https://www.linux.com/learn/understanding-linux-file-permissions

Answer 2

First, you need to copy entrypoint.sh file into other directory instead of same your source code (Eg. /home/entrypoint.sh), then grant permission to execute entrypoint script:
RUN ["chmod", "+x", "/home/entrypoint.sh"]

Solution
ENV USER root
ENV WORK_DIR_PATH /home
RUN mkdir -p $WORK_DIR_PATH && chown -R $USER:$USER $WORK_DIR_PATH
WORKDIR $WORK_DIR_PATH
Info
The USER instruction sets the user name (or UID) and optionally the user group (or GID) to use when running the image and for any RUN, CMD and ENTRYPOINT instructions that follow it in the Dockerfile.
The WORKDIR instruction sets the working directory for any RUN, CMD, ENTRYPOINT, COPY and ADD instructions that follow it in the Dockerfile. If the WORKDIR doesn’t exist, it will be created even if it’s not used in any subsequent Dockerfile instruction.

A pretty common solution if nothing works is to re-install Docker.. That's what ended up working for me after trying for like 5 hours everything under the sun in terms of permissions etc.
