Networking is hard. Kubernetes networking can be even harder. On one hand, kubernetes provides a nice abstraction of infrastructure underneath. On the other hand, k8s contributors and cluster operators bear the burden to seal the gap. Especially for kubernetes networking, it has to work seamlessly with both k8s internals and underlying infrastructure. This brings challenges for understanding and troubleshooting the system. In this talk, we will share real-world experience in running Google Kubernetes Engine and explore the pain points in the current kubernetes networking design, troubleshooting best practices and future improvements.
