#docker run --name="postgis" -e POSTGRES_USER=qgis -e POSTGRES_PASS=qgis -d -v
#/var/docker-data/postgres-dat:/var/lib/postgresql -t qgis/postgis:6

# If you dont specify a user/password in docker run, we will generate one
# here and create a user called 'docker' to go with it.

# Only create credentials if this is a master database
# Slave database will just mirror from master users
