Configuring Container Networks
Create and manage custom Docker networks to isolate and connect your services effectively.
Why Custom Docker Networks?
Docker provides default networks, but for complex applications, custom networks are key. They offer better isolation and controlled communication between your services.
Think of them as private virtual LANs just for your containers, giving you more control over how they interact.
Default Networks: Bridge, Host, None
When you run a container without specifying a network, it usually attaches to the bridge network by default. This allows containers to talk to each other and the host.
- Bridge: Default, isolated.
- Host: Container shares host's network stack.
- None: Isolated, no network access.
While useful, the default bridge network can be limiting for multi-service applications.
