Simple case - no hooks, etc:

runc create --name=test --process=myapp

or if you need hooks, etc... :

runc create --name=test
            # process is just "sleep"
            # creates a new container will all new NSs
            # do pre-start hooks here
runc create --attach=test --ns=all --process=myapp
            # creates a new container but attaches to all NSs from "test"
            # when 'myapp' is done, no NSs are deleted because it didn't create them, "test" did.
            # Note, there's an implied "runc delete" for this nested container
            # do post-stop hooks here
runc delete --name=test
            # this deletes all of test's NSs since it created them

I guess --process isn't right since it gets it from the config.json, but I added it just to show what the PID process is in each case
