Can't connect to mysql docker when using phpmyadmin docker

I'm just getting started in docker and maybe I'm starting of a little big but I found an article that explained out to get a coldfusion install (run by commandbox) up with mysql. This docker compose works just fine. I had the idea of adding in phpmyadmin so that I can us that to connect to mysql.

For reference the original article is here: https://cfswarm.inleague.io/part3-docker-in-development/part3-running-docker

So I modified the docker compose yml pull in the phpmyadmin

So right at line 63 I added in the pull for phpymyadmin which appears to work, it does answer on port 8082 but it gives me an error:

MySQL said: Documentation

Cannot connect: invalid settings.
 mysqli::real_connect(): php_network_getaddresses: getaddrinfo failed: Temporary failure in name resolution
 mysqli::real_connect(): (HY000/2002): php_network_getaddresses: getaddrinfo failed: Temporary failure in name resolution
 phpMyAdmin tried to connect to the MySQL server, and the server rejected the connection. You should check the host, username and password in your configuration and make sure that they correspond to the information given by the administrator of the MySQL server.

The one thing that I could not get to work was adding in the network of cfswarm-simple. When I tried to add the line right under ports (line 72) I would get an error when trying to start the docker compose.

Right now, I'd like to be able to connect to the mysql docker with the docker of phpmyadmin.

TIA

I was able to figure out that it was a spacing issue. Make sure any new entry matches the spaces that are used before.
