Summary: Resolving Docker Container Networking Errors

Reviewing network drivers for Docker

In this chapter, we discussed various drivers like bridge, host, and none and talked about network isolation for different containers.

• The bridge driver network: In a bridge network, each container runs in its own network namespace with a private IP address. Also, containers on the same bridge network can communicate with each other using their internal IP addresses.

• The host driver network: In a host driver network, the container shares the network namespace with the host system. This means the container uses the same network stack as the host, including the same IP address. This mode is useful when we need direct access to the host’s network.

• The none driver network: In a none driver network, the container isn’t attached to any network. The container has no network connectivity, including internet access or communication with other containers. It’s a completely isolated network environment. This is only employed where network isolation or custom network configuration is required. We also explored some network driver errors and how to resolve them. ...
