Is the persistent volume required?

Not really an issue, more of a query on the build - what the impact of not having the volume (defined as follows)

volumes:
  - /data/misp:/var/www/MISP

remain persistent is. i.e. if the volume is not created, the container restarted and changes lost, the application appears to still run normally.

Commenting out the volume mount instructions allowed my stack to start correctly.. It was a PITA and not starting for a long while.
"mysql:5.7" is the image in use and working.

"mysql/mysql-server:5.7" image did not work with or without commenting the volume mount instructions. (also tried ":Z" appended to the mount path with no joy.
