Laravel - not connection to DB on docker

Question

I'm trying to run Laravel with postgres db. Docker build works fine I have access to app thru url and can connect to db. But laravel cant establish connection to db.

My connection to db using phpstorm client works:

But when I use the same credentials in env file:

then I have following error.

Doctrine\DBAL\Driver\PDOException : SQLSTATE[08006] [7] could not connect to server: Connection refused Is the server running on host "127.0.0.1" and accepting TCP/IP connections on port 5432?

I was having the same problem. It worked by changing the DB_HOST to the same name as the database service in the docker-compose file.
