Answer 1

We're using symfony with doctrine and we are in the process of automating deployment. I got this error when I simply hadn't provided the correct db creds in parameters.yml (I was running doctrine:migrations:migrate)

This thread has sent me on a bit of a wild goose chase, so I'm leaving this here so others might not have to.

I'm using Laravel with Docker. I solved this problem by changing the value of DB_HOST from localhost to mysql.

DB_HOST=mysql
