Deep dive into Kubernetes network model and communication

This is the first note on Kubernetes network learning. In this series, we will explore the Kubernetes network model and communication through the following articles: <ul> <li><a href="https://medium.com/@addozhang/deep-dive-into-kubernetes-network-model-and-communication-57a2bffc852e" rel="noopener">Deep Dive into Kubernetes Network Model and Communication</a></li> <li><a href="https://addozhang.medium.com/introduction-to-container-network-interface-cni-25309a64b23e" rel="noopener">Understanding the Container Network Interface (CNI)</a></li> <li><a href="https://medium.com/@addozhang/source-code-analysis-understanding-cnis-usage-from-kubelet-container-runtime-24d72f29466b" rel="noopener">Source code analysis: how kubelet and container runtime work with CNI</a></li> <li><a href="https://addozhang.medium.com/learning-kubernetes-vxlan-network-with-flannel-2d6a58c95300" rel="noopener">Learning Kubernetes VXLAN network from Flannel</a></li> <li><a href="https://addozhang.medium.com/kubernetes-network-learning-with-cilium-and-ebpf-aafbf3163840" rel="noopener">Kubernetes network learning with Cilium and eBPF</a></li> </ul> Kubernetes defines a simple and consistent network model based on a flat network structure. This design allows for efficient communication without the need to map host ports to network ports or use other forwarding components. The model also makes it easy for applications to migrate from virtual machines or physical machines to pods managed by Kubernetes. In this article, we will dive into the Kubernetes network model and understand how communication takes place between containers and pods. The implementation of the network model will be covered in later articles. <a href="https://addozhang.medium.com/deep-dive-into-kubernetes-network-model-and-communication-57a2bffc852e">Visit Now</a>
