I have three Docker containers running on Mac OS sierra, namely web
, mysql
and mongo
, and have linked both mongo
and mysql
into web
, which is essentially a Ubuntu Xenail base, with Apache and PHP added.
I am currently mounting my local Symfony project into the web
container, and that seems to be working fine, but when I try to interact with the DB in any way, I get:
An exception occured in driver: SQLSTATE[HY000] [2002] Connection refused
I've tried almost every combination of parameter values, but keep getting the same result.
I suspect it might have something to do with the way that I am linking the containers?
I'm in the process of learning Docker, so please excuse my limited knowledge.
Thanks!

UPDATE:
So I've moved over to using docker-compose
, but am still receiving the same error.
