There is one sentence in dockerfile:
COPY supervisord.conf /etc/supervisord.conf
The construction was successful, but the file could not be found when entering the container. Why?
In addition, why can’t this container be entered with doc-composesexephp-workerbash, but with doc-composesexephp-workersh?
The complete dockerfile is as follows:

You should use add instead of copy. In addition, the php image you use is based on alpine. alpine has no bash, only sh
