$ 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
