fix the problem and build the docker

Solution

  • In a comment, you cite this line as the problem:

    RUN service apache2 restart

    You can safely delete this line.

    A Docker image doesn't include any running processes. Instead, it contains the image's filesystem and some metadata describing what to do when the container starts. If you change a configuration file in a Dockerfile, you don't need to restart the service: it's not running right now, and when you eventually docker run a container from the image, it will start its process for the first time, and that will read the configuration file.

    Since a container only runs a single process, it doesn't generally run any sort of process manager, and so service, systemctl, and similar commands frequently don't work. Your image seems to have a setup where service tries to interact with a supervisord, but again, that's not running during the image build, so RUN service ... fails with the error you show. You shouldn't usually need to run service at all in a Docker context, and it won't typically work.
