# integrating the work of the following devs:
#   - Adrian Perez (mariadb and Docker volumes): https://adrianperez.org/advanced-deployment-of-ghost-in-2-minutes-with-docker/
#   - Docker compose file reference (the Right Way™ to do volumes): https://docs.docker.com/compose/compose-file/#service-configuration-reference
