Docker Custom Bridge Networking: Static IPs & Internal DNS Explained
Ever tried to ping a Docker container by its name and it just... failed? Most people use the "Default Bridge," but there is a major limitation: it doesn't support internal DNS. In this deep dive, I show you why your containers are "blind" to each other and how to fix it by building a User-Defined Custom Bridge Network.
What you’ll master in this demo:
✅ The "Secret" Limitation of the Default Docker Bridge
✅ How to enable Automatic DNS resolution between containers
✅ Manual Control: Assigning Static IP Addresses to your containers
✅ Networking Multi-Tool: Connecting one container to multiple networks
✅ Behind the Scenes: What happens to your IPTables when you create a network?
