Hi there,

What I usually do is to create a Docker network and attached the containers to the same network. Then you could use the name of the MySQL container for your connection string.

Here is how you could do that:

This is a good practice as your database connections would not have to go through the public Droplet IP but would be routed internally via the Docker network.

Let me know how it goes. Regards, Bobby
