Why strace doesn't work in Docker
- downerending 6y agoInteresting. And quite annoying that Docker would disable ptrace(2) within its containers by default.
- richardwhiuk 6y agoIt doesn't if you are running Linux 4.8 or above
- downerending 6y agoInteresting. Is this a change in Docker, or a change in the 4.8 kernel? Any idea why?
- richardwhiuk 6y agoDocker detects a different kernel, and that's a result of what I assume is a bug in Linux prior to 4.8 where you could get around a seccomp filter I believe.
