Sudo ip link add dev bridge_home type bridge Let’s make sure IP forwarding is enabled by running: How do Kubernetes and Docker create IP Addresses?! create network namespaces and virtual devices I recommend going back and reading my previous post, This post will assume you’re familiar with network namespaces and virtual interfaces.

Requests from a port in the host network namespace to an IP address and port residing in another

This post focuses on the other technique Docker uses, iptables, which can also be used to forward Namespace and makes requests to a container’s network namespace. When the docker run command is instructed to publish ports.ĭocker (version 19.03.6) uses a couple of techniques including a proxy that binds a port in the host network This will help us understand what Docker does Now we’ll learn how to make a request to 127.0.0.1:8080 orġ92.168.0.100:8080 (a local IP address) and forward the request to an HTTP server running in our network namespace. In the previous post, we created our own network namespaces, virtual interfaces,Īnd assigned IP addresses to these virtual interfaces. Is “How does Docker handle publishing ports?” How do Kubernetes and Docker create IP Addresses?!

The next question to answer after writing

Docker iptables
