One MySQL Docker Container for Multiple Docker Apps!

Create an internal network so Docker containers can communicate without exposing ports on your host machine. In this video I show you the current "best practice" for getting Docker containers to talk to each other behind the scenes.

Generally, we love that containers don't interfere with each other, but we also don't want to include an entire MySQL server inside every app we create. Using this method, we can have a single MySQL instance running in a container, and use it for all our other containers.

Hello Shawn, just found your video, I`m trying to install NGINX Proxy + Wordpress + NextCloud on my NUC and unfortunately I`m just copy/paste Linux user and have zero experience with mySQL. I have killed 5 days already trying to install all 3 containers and every time I either get Wordpress database error or won`t be able to log in to NGNIX etc..


wanted to ask if you have time what would be the new method using the mySQL bridge method you are explaining in your video.

Perhaps creating video showing how to install multiple containers using Portainer for users like me could be usefull to many.

cheers.
