Surviving Day 2 - How to Troubleshoot Kubernetes Networking - Thomas Graf, Isovalent
Kubernetes is widely deployed. Kubernetes networking is at the core of every platform and then there is DNS. In this talk, we will dive into the inner workings of Kubernetes networking, learn how to troubleshoot it, and most importantly, describe how to monitor it properly to prevent incidents in the first place. In this session, we will walk through the essential toolbox for efficient networking troubleshooting and then set up preventive measures together: - Understanding the Kubernetes networking model - How to troubleshoot and resolve DNS errors - Debugging Kubernetes Services & Ingress and increasing resiliency - Locating the source of networking errors - Is it an app, CNI, or underlying network problem? - Troubleshooting Kubernetes Network Policy drops - How to set up metrics dashboards and alerting to prevent network incidents All troubleshooting steps will be demonstrated in a live Kubernetes cluster and all steps will be found in the presentation slides and on GitHub.
