The Environment Puzzle

A startup script /opt/app/run.sh sources config from /opt/app/config.sh then launches /opt/app/app.py. The Python app needs DB_HOST, DB_PORT, and DB_NAME as environment variables, but config.sh sets them without exporting -- so the child process never sees them. Fix /opt/app/config.sh so the variables are properly exported. Then run: bash /opt/app/run.sh The watcher checks for /tmp/app_status.txt containing "connected".
