Container Networking Basics
Understand Docker's default networking, bridge networks, and how containers find each other.
Why Container Networking?
Containers are isolated by design, which is great for security and portability. However, for applications to be useful, they often need to communicate with each other and the outside world.
This is where Docker networking comes in! It allows containers to talk securely and efficiently.
Docker's Default Bridge Network
When you run a container without specifying a network, Docker automatically connects it to the default bridge network. This network is named bridge.
Containers on this network can communicate with each other using their IP addresses, and they also get access to the internet.
