Permissions issue

docker: Error response from daemon: oci runtime error: container_linux.go:247: starting container process caused "exec: \"/data/ops/docker-entrypoint.sh\": permission denied".

Dockerfile file

VOLUME ["/data/ops"]

RUN mkdir -p /data/ops
COPY . /data/ops
WORKDIR /data/ops

RUN python3 -m pip install -r requirements.txt -i https://pypi.douban.com/simple
RUN chmod 777 /data/ops/docker-entrypoint.sh
RUN ls -lah /data/ops
EXPOSE 4000

ENTRYPOINT ["/data/ops/docker-entrypoint.sh"]
CMD ["gunicorn", "--bind","0.0.0.0:4000","-w","4","app.create_app()", "--access-logfile", "/data/ops/app/logs/access.log", "--error-logfile", "/data/ops/app/logs/error.log"]

The results show that

-rw-r--r-- 1 root root  308 Apr  9 20:11 docker-entrypoint.sh

Shouldn’t I have permission?
