docker里面不能进行gdb调试

To attach to an application on Linux, login as super user or set ptrace_scope to 0.
See https://aka.ms/miengine-gdb-troubleshooting for details.

三个解决方案

1

echo 0| sudo tee /proc/sys/kernel/yama/ptrace_scope

2

sudo setcap cap_sys_ptrace=eip /usr/bin/gdb

Alternatively, launch GDB as super user and attach to processes. Use root@machine to login with a password or certificate. Note, many Linux distros are configured to disallow root login through SSH for security reasons. You may have to configure /etc/ssh/sshd_config to allow root login with certificate or password. You can verify SSH connection via a client like putty.exe in windows.
