 To run the services with an at scale database, starting from a stand alone database from the this project can be accomplished with minor alterations to the docker-compose.yml to allow the two docker-compose projects to communicate on the same network. 
 
-Adding the following to docker-compse.yml allows connection to a pre-existing external docker network.
-```
-networks:
-  nldi:
-    external: true
-```
-
-Each service that needs to use that network then needs a `networks` element as in:

-  version: '3.3'

-  services:
-    nldi-services:
-		.
-		.
-		.
-      networks:
-        - nldi
-```

-With `networks` configured in docker-compose, the environment for the services need to match that of the database and things will connect. For the current (6/8/23) compose environment, that looks like the following.

-NOTE: nldiDbHost is the name of the docker-compose service in the nldi-db project. nldidbUsername and Password need to be synced between the two projects.
