Does not honor env pass about docker-ttrss

It turns out that there are a number of things you need to set to get the database configuration script to run through happily. See root/srv/ttrss-configure-db.php for exactly what's going on. Try adding these:

• DB_PORT=5432
• DB_PORT_5432_TCP_ADDR=172.17.0.1 (to use your example)
• DB_PORT_5432_TCP_PORT=5432

(Those last two will get automatically set under some conditions if you use --link [somecontainer]:db, but not, say, with docker-compose and a Compose file of version 2 or later.)

The latest updates to the Docker image should work with those environment parameters -- just tested that myself.

I docker rmi-ed and pulled a fresh image down. I still cannot get this to connect to postgres on 172.17.0.1 or get my user in. Still connects as fox to localhost database fox.
