Every port is published on 127.0.0.1 only: Docker writes its own iptables rules, so a plain 3306:3306 is reachable from the internet on a server even with ufw denying it. depends_on with condition: service_healthy waits for the healthcheck, not just for the container to start.

About this tool
Method, assumptions, practical next steps, and limits.
Publish on localhost
Docker inserts its own iptables rules for published ports, ahead of ufw's, so 3306:3306 on a server is reachable from the internet even with the firewall denying it. Binding to 127.0.0.1:3306:3306 keeps a database private. The packet filtering documentation explains the interaction.
Healthchecks and start order
depends_on alone only waits for a container to start, and a database accepts connections seconds later. With a healthcheck and condition: service_healthy, the app waits until the database answers, which removes the retry loop most entrypoint scripts carry.
