DB, API-GATEWAY & AUTH waiting to start

[ZuluPilgrim]

Can't work out what I might have done wrong.

I have checked my ports and db passwords

db:3309 is unavailable yet - waiting for it to start

==> logs/api-gateway.log <==
localhost:3103 is unavailable yet - waiting for it to start

==> logs/auth.log <==
localhost:3101 is unavailable yet - waiting for it to start

The logs report a bad DB address

==> logs/api-gateway.err <==

==> logs/auth-worker.err <==

==> logs/auth.err <==

==> logs/files-worker.err <==

==> logs/files.err <==
==> logs/revisions-worker.err <==

==> logs/revisions.err <==

==> logs/syncing-server-worker.err <==

==> logs/syncing-server.err <==
nc: bad address 'db'
