The doc says:
> For MESOS_HTTP, MESOS_HTTPS, MESOS_TCP, TCP, HTTP and HTTPS health checks, either port or portIndex may be used. If none is provided, portIndex is assumed. If port is provided, it takes precedence overriding any portIndex option.
However it fails to deploy when only port is specified, and not portIndex:
It works if I set portIndex: 0 and then override it with port: X, but that's likely not expected behaviour.
