How can I set up GDB for remote debugging in Docker?

To set up GDB for remote debugging in Docker, you need to run your container with the appropriate flags and expose the GDB server port.

What flags do I need to use when running the Docker container?

You should use --cap-add=SYS_PTRACE and --security-opt seccomp=unconfined to allow GDB to attach to the process.

How do I connect to the GDB server from my host machine?

You can connect using the command gdb -ex 'target remote <host_ip>:<port>' where <host_ip> is your Docker host and <port> is the port you exposed.

Are there any specific configurations needed in my Dockerfile?

Yes, ensure that your Dockerfile installs GDB and any necessary debugging symbols for your application.
