Thanks for your great work. Just wondering if it's possible for you to provide a docker image. I tried many times to get it running, but always come into new problems every time. Having a docker image would greatly increase convenience. Thanks!

I think the ebpf is hard to run in the docker without privilege and should map the /sys/ in, and you still need your eBPF of your kernel version. I guess the pitfalls are 1. /sys/fs/kprobe, you can set env LOGV=1 to see whether it's opened or not. 2. you should in the same directory to run the code, since it read relative path to eBPF kernel object. If you really want a docker image to compile or run. please refer to this repo and this image.

Thanks for your help, but I am still experiencing core dumped issue with the image you provided. image I've tried different workloads, but all have the same problem. Do you have any idea about this?

Debug and take a look at this https://linux.die.net/man/2/perf_event_open. Normally it's CPU not -1 or PID has no permission.
