I will demo how to use different BPF tools in the Kubernetes developer workflow. Then, I will explain how it works and what support it requires from the Kubernetes installation.
BPF tools for tracing your Linux system is an area with a lot of developments. This has happened in the bcc project and in bpftrace project. Until recently, bcc and bpftrace were designed to trace one Linux system. This is changing with kubectl-trace, a tool adapting bpftrace for the Kubernetes workflow.
I’ll present how to use kubectl-trace to trace a Kubernetes pod. I will also present new tools based on bcc to trace syscalls or files opened by a specific pod. Finally, I will explain how it works and what support it requires from the Kubernetes installation.
