Multiple Docker Container

[Hubsdaa Zidasner]

Hello I'm trying to run two different MySQL versions as docker containers, however when I want to connect a second wordpress blog, I'm greeted with this error message: Error establishing a database connection.
In the container logs everything is looking fine and I did change the network section and ports in my docker-compose.yml, but from looking at the container information I see that the MySQL container is still using 3306/tcp as port, even though I changed it with the environment variable MYSQL_TCP_PORT: 3307 and it is using this one as well.

Running two independent setups is mandatory.
Thank you for your replies!
