when I execute a shell script in docker container, the error is "No such file or directory"

Question

My Dockerfile：

FROM centos:7.2
COPY gateway-deploy-1.1-SNAPSHOT /home/admin/gateway/
COPY entrypoint.sh /home/admin/entrypoint.sh
RUN chmod +x /home/admin/entrypoint.sh
EXPOSE 12366
VOLUME ["/home/admin/logs"]
ENTRYPOINT ["sh", "/home/admin/entrypoint.sh"]

When I start the container, entrypoint.sh should be executed, but the system prompts "No such file or directory". I tried to change the startup command to "/bin/bash" and then went to the container to see that the file exists.

Why is this problem? I have tried to make images many times, but this problem has always existed.

And did you find this file when manually strafing thrgough container? — grapes

Your Dockerfile is fine (apart from the tag centos:7.2 which isn't available (at least not for me, I had to use centos:latest). Presumably, entrypoint.sh references another file which cannot be found - please post the contents of entrypoint.sh — Frank Schmitt

Since I mounted an empty directory from the host to the path /home/admin when I started the container, the file was overwritten. So this is not a problem, but my mistake.
