volumes:
          - /opt/private/test/7200/start.sh:/usr/local/bin/docker-entrypoint.sh

You're overriding the entrypoint, so the issues you're encountering are from that start.sh. Also looks like some lines are being single quoted and not interpolated? https://www.gnu.org/software/bash/manual/html_node/Single-Quotes.html
Also it's a hefty security risk to run privileged containers

Questions like these should be asked over at the Docker Community Forums, Docker Community Slack, or Stack Overflow. Since these repos aren't really a user-help forum
