Summary of Docker networking is CRAZY!! (you NEED to learn it)

00:00:00 - 00:35:00

This video discusses the different types of Docker networks and how they can be used to deploy virtual machines and isolate containers. It also demonstrates how to create a new network and add containers to it.

• 00:00:00 Docker networking is crazy! You need to learn it because it's a key part of using Docker containers. There are seven different types of networks that you can use with Docker, and the default network is the bridge network.
• 00:05:00 In this video, the presenter demonstrates how Docker networking works by deploying two containers and switching between them using the command "Docker run". Each container is assigned an IP address and has its own DNS server. The presenter also demonstrates how to access a website that is hosted inside a container using the command "Docker exec".
• 00:10:00 Docker networking is a complex and useful topic, and this video illustrates the basics of how networks work and how to create your own using Docker. The video introduces the concept of isolation, and explains that using a user defined bridge (instead of the default bridge) is the best way to achieve that. After the introduction, the video goes on to show how to create a network using the user defined bridge and how to add containers to that network. The video then moves on to showing how to use Docker's networking features to inspect and interact with containers on other networks. Finally, the video finishes with a brief discussion of how to use bit defender to protect your computer and privacy.
• 00:15:00 Docker networking is a complex topic, but it can be easily simplified with the use of networks like the Mac VLAN. This network allows containers to be connected directly to the physical network, without the need for separate virtual networks or interfaces.
• 00:20:00 In this video, the author demonstrates how to use Docker networking to deploy virtual machines on a new network. They first show how to deploy a virtual machine using the "new" network type, Mac VLAN. They then demonstrate how to use bridge mode to connect the virtual machines to the existing network. Finally, they show how to use do one cue mode to limit the number of virtual machines that can be concurrently running on the network.
• 00:25:00 In this video, Docker networking is explained in detail. Docker networks allow for direct connections between containers and the host's network, eliminating the need for switches and ARP. IPVLans allow for sharing of a host's MAC address among containers.
• 00:30:00 In this video, Docker networking is explained in detail. Layer three networks allow for more isolation and control of containers, as well as more flexibility when it comes to routing. A new network, called "new Asgard," is created and deployed. Thor, a container on the new network, can't reach the internet, but has a route out. When Thor tries to go out, his route is to a network on the same physical interface as the new Asgard network.
• 00:35:00 This video discusses the seven different Docker networks, which can be useful for isolating containers on a single host or for routing traffic between different hosts.
