As someone who runs a similar setup (an OCI container as a DC and host
as domain member), I recommend your host to have two IPs, one for the
host services and one for services published by the container. services
with ports that collide between both environments should be configured
to bind to explicit IP addresses.
In my case the host runs an instance of Bind DNS for non AD related
domains, so I have to modify the Bind configuration to only bind to the
host public IP and not bind the the container dedicated public IP.
