delve: Ubuntu, could not launch process: fork/exec ./debug: operation not permitted

I’m on Ubuntu 14.04 and I am not sure what I’m doing wrong to get this error when I run dlv debug:

could not launch process: fork/exec ./debug: operation not permitted

I’m simply following the instructions at: https://github.com/derekparker/delve/wiki/Building#linux

Alright, so you’re running within a Docker container. Docker has security settings preventing ptrace(2) operations by default with in the container. Pass --security-opt=seccomp:unconfined to docker run when starting.

I ran into this and it took awhile for my google search to find this. Is there a way dlv can know that it’s running into this particular error and output a helpful hint?

since i run in a managed k8s pod I have no access to docker launch param , is there any other way to debug ?
