[Docker] Explore Docker’s bridge network from the perspective of namespace and routing
Bridged networking is Docker’s default networking mode. In a bridged network, Docker creates a virtual network interface for each container and assigns the container an IP address. Containers can communicate with the host and other containers through bridged networks, and can also expose ports for external access. Principle of communication between containers First we create […]
[Docker] Linux routing connects two different network segment namespaces, connecting the namespace and the host
If the two namespaces are in different subnets, they cannot be connected through the bridge. Instead, they need to perform Layer 3 forwarding through the router. However, Linux does not provide a virtual router device like a virtual bridge because Linux itself has a router function. The working principle of the router is this: there […]
