Docker Compose Settings

[sherman94062]

Hey all, love, love, LOVE this repo!! When I last ran Druid in Docker, I ran into issues with memory and disk space. I believe that when you bring up the Docker cluster, you need to specify the following in your docker-compose.yml:
volumes:
metadata_data: {}
middle_var: {}
historical_var: {}
broker_var: {}
coordinator_var: {}
router_var: {}
druid_shared: {}

Did you all set those up so that this cluster can "persist" if we need to bring it down?

Thanks for the question @sherman94062 , cross posting the answer from slack, here.

The docker volumes are created if they do not exist and will persist through a shutdown or restart of the services. In order to remove them, you need to use the -v flag; the default (no -v flag) will keep the volumes available for the next restart.
