[AGPT-631] Fix docker setup

[Swiftyos]

The docker setup was not working for me as the app could not communicate with the Postgres server.

To fix this for me I've done the following:

• explicitly define the network
• expand the health check for the Postgres sever

In addition, I've added an updated .env.example file and updated all the commands to use the env var defined in the file

I'm still hitting intermittent errors:
