Tcpdump for Kubernetes Network Troubleshooting and use Fluentd to stream the logs.
Leverage Tcpdump to Simplify Kubernetes Network Diagnostics.
Kubernetes is the go-to container orchestration platform for managing large-scale applications, but as its network architecture scales, so does the complexity of troubleshooting network-related issues. Whether you’re dealing with inter-pod communication, cluster services, or DNS problems, quick and efficient diagnosis is essential to maintain smooth operations.
One powerful tool for troubleshooting Kubernetes networking issues is Tcpdump. Tcpdump is a packet sniffer that captures network traffic at a very detailed level, making it ideal for resolving a variety of networking problems such as slow communication, unreachable services, or misconfigured routing.
This article will walk you through using Tcpdump in Kubernetes environments to help you troubleshoot network issues faster with fluentd and with greater precision.
