Even though I’m setting the proper permissions in a Dockerfile, docker-compose up throws an error:

Attaching to lab-track-raport-app-db-1, lab-track-raport-app-web-1

Error response from daemon: failed to create shim task: OCI runtime create failed: runc create failed: unable to start container process: exec: "./docker-entrypoint.sh": permission denied: unknown

My Dockerfile:

# syntax=docker/dockerfile:1
FROM python:3.9
ENV PYTHONDONTWRITEBYTECODE=1
ENV PYTHONUNBUFFERED=1

# Set workdir
WORKDIR /code

# Copy project files
COPY . /code/

# Install dependencies
# RUN pip install -r requirements.txt

# Add permissions for the entrypoint file
RUN chmod +x "./docker-entrypoint.sh"

# debug
RUN ls -la .

# maybe it's overwritten when mounting volume? set permissions again
CMD ["chmod", "+x", "./docker-entrypoint.sh"]
ENTRYPOINT ["./docker-entrypoint.sh"]

docker-compose.yml:

version: "3.9"

>Solution :

You copy your code into the /code directory, but then at runtime you also map your current directory onto /code which then ‘hides’ the /code directory in the image and replaces it with the current directory from your host machine.

Remove the volume mapping, so the container can use the /code directory in the image
