Following the instructions here:
https://docs.graylog.org/en/3.3/pages/installation/docker.html#persisting-data
, I set the volumes to be in /usr/share/[mongo | elastic | graylog]/data, each service pointing to their own volume.
After doing docker-compose up, I expected to see /usr/share/* directories created on the host computer but they are not created. What am I missing?
