I run a number of WordPress sites using docker-compose (and nginx-proxy). So I can use the same docker-compose file for each site I use .env. I want each of the MariaDB containers to use different ports (as they are sharing the same external docker network).
What I have is the below compose file but when I bring it up I get.
MySQL Connection Error: (2002) Connection refused
Previously I was using the same compose file without the ports: section and with the port hardcoded in the WordPress section and it worked.
Where did I go wrong?
