如何使用laradock与postgres配置laravel？ 无法连接到服务器：端口5432上的连接被拒绝

Question

Im starting a new laravel project and im trying to configure to run it with laradock postgres container. I have the postgres container running in port 5432 but when i run:

docker-compose exec workspace bash
php artisan migrate

im getting the error:

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?")

Seens Laravel can't find postgres. I must be missing something.

To build the containers i ran this in my-laravel-app/laradock/ :

docker-compose up -d nginx postgres

and i can check everything is up and running fine typing docker-compose ps :

           Name                          Command              State                     Ports

I typed lsof -Pan -i tcp and i can see that postgres container is running in port 5432:

com.docke 693 marcelo   18u  IPv4 0x483d469672d04c2b      0t0  TCP *:5432 (LISTEN)
com.docke 693 marcelo   21u  IPv6 0x483d46967542a923      0t0  TCP [::1]:5432 (LISTEN)

For future searchers: Your project .env should look like this:

DB_CONNECTION=pgsql
DB_HOST=postgres *(no need to use the full container name, as Laradock exposes 'postgres' as the volume name (check docker-compose.yml))*
DB_PORT=5432
DB_DATABASE=mydb (postgress database you want to connect)
DB_USERNAME=root (postgres user)
DB_PASSWORD=root (postgres password)
