In Chapter 1, Linux Networking Constructs and Chapter 2, Configuring and Monitoring Docker Networks, we reviewed common Linux network constructs as well as covered the Docker native options for container networking. In this recipe, we'll walk through how to manually network a container the same way that Docker does in the default bridge network mode. Understanding how Docker handles networking provisioning for containers is a key building block in understanding non-native options for container networking.
In this recipe, we'll be demonstrating the configuration on a single Docker host. It is assumed that this host has Docker installed and that Docker is in its default configuration. In order to view and manipulate networking settings, you'll want to ensure that you have the iproute2
toolset installed. If not present on the system, it can be installed by using the command:
sudo apt-get install iproute2
In order to make network changes to the host...
