Help with understanding user proc bootstrap

[solventak]

Hello,

First of all, I'd like to say thanks for working on this! It's had me captivated all weekend. I'm having some trouble understanding how to actually spawn user procs once SigmaOS is running.

My Understanding So Far

• In the tutorials, which I completed, the kernel seems to be run from the test state
• From there, you get a sigmaclnt which is used to spawn procs
• I'm confused about when SigmaOS is actually standalone running though

My Main Question

• How do I spawn userprocs when SigmaOS is running in a docker container? Seems as though we can spawn procs from a proc that is already running in the cluster, but I'm not sure how to actually bootstrap that "root process" first.

I must be missing something. I've looked through all of the other examples like hotel from He's thesis but the only place I can see the procs starting is from test scripts and not a way to start that on an actual cluster.

Thanks for any clarification you can provide!

I think that I may have made some progress here...

pe := proc.NewTestProcEnv(sp.ROOTREALM, secrets, etcdMnt, localIP, localIP, tag, false, false)
_, err = sigmaclnt.NewSigmaClnt(pe)
if err != nil {
	debug.DPrintf(debug.ERROR, "Error newSigmaClnt: %v", err)
	panic(err)
}

When I run with ./mount.sh --boot 127.0.0.1 and then run this on my local machine I'm not getting any errors, which leads me to believe that I connected with a client that is running outside of SigmaOS. Is this advised? I bet that I'll be able to spawn user procs from my local machine with a client running in a Go binary application connecting to SigmaOS that is running in a Docker container.
