本文介绍在Docker容器内使用strace时遇到的Operation not permitted错误及解决方法。通过添加--cap-add=SYS_PTRACE、--security-opt seccomp=unconfined和--security-opt apparmor=unconfined选项，可以成功在Ubuntu18.04环境下进行gdb调试。

在docker里面用strace -p pid 查看进程当前调用栈报错

$ strace -p 7
ptrace(PTRACE_ATTACH, ...): Operation not permitted   //报错信息

解决办法

I would like to add that I needed --security-opt apparmor=unconfined along with the options that @wisbucky mentioned. This was on Ubuntu 18.04 (both Docker client and host). Therefore, the full invocation for enabling gdb debugging within a container is:
docker run --cap-add=SYS_PTRACE --security-opt seccomp=unconfined --security-opt apparmor=unconfined
