remote debugging application inside a greengrass docker component

Question

i read that i can remote debug an application in a docker container by starting the container like

```
docker run --cap-add=SYS_PTRACE --security-opt seccomp=unconfined -it 
```

however i don't think i can run a docker component with the -it 'interactive flag'

without the -it flag if i try to connect to a running process in the docker i receive a

```
Unable to start debugging. Attaching to process 29966 with GDB failed because of insufficient privileges with error message 'ptrace: Operation not permitted.'.
```

error.

how does anyone else debug inside a greengrass container ?

The "ptrace: Operation not permitted" error message usually occurs when you are trying to attach a debugger to a process running inside a Docker container and the container is running in a restricted environment or with insufficient privileges, In some environments, such as when running Docker containers with default security settings, ptrace is not allowed by default due to security concerns.
