Yeah, at previous jobs there has been a db.devopsdomain.com (etc) which acted like a bastion into the network from which you could connect with DB credentials to the actual databases.
It's convenient I will say that. I've tried not to replicate this exactly and instead have adminer running on a server on the network but only listening to localhost connections. To get access to it you can then SSH tunnel the ports locally:
> # Route 8082 on your machine to localhost:8080 on the server:
> ssh -N -L 8082:localhost:8080 db.devopsdomain.com
