initial user account

I installed a local docker container instance from here:   intersystemsdc/iris-community

I'm trying to login:    http://localhost:52773/csp/sys/UtilHome.csp

I thought if I used SYSTEM as the initial username, I could login, but I get #822 Access Denied.

Is that the correct username? maybe there's a better location to pull the docker instance.
