Current Behaviour?

In ops-devnet/docker-compose.yaml, set pid to host on kanvas-node.

kanvas-node:
  pid: host

And then set ptrace_scope to 0

> sudo su -
> echo 0 >  /proc/sys/kernel/yama/ptrace_scope

And then if I try to debug by attaching go process is rejected with this message.

Failed to attach: Could not attach to pid 39997: current user does not own the process.

Which feature do you want to expect?

I expect the process is launched with uid:gid so that we are able to debug. Currently, we should rely on the log message, which is very difficult when we consider that the logs are emitted so long.
