setup

docker build -t gdb_container .
docker run -it --cap-add=SYS_PTRACE --security-opt seccomp=unconfined gdb_container bash

explanation:

• SYS_PTRACE is a Linux capability that allows a process to trace other processes using system calls like ptrace()
• seccomp (Secure Computing Mode) is a Linux kernel security facility that allows a process to restrict the set of available system calls it can make. Docker applies a default seccomp profile to containers that blocks potentially dangerous system calls.
  • unconfined tells Docker to disable the default seccomp security profile for this container.
