Q:

Is it possible to have two host identifications for a single domain?

I'm running a docker container that expects SSH traffic on port 22.  The host machine also expects SSH traffic, but on port 2222.
While SSH-ing on port 2222 works without hickups, my SSH client complains that the remote host identification has changed when SSH-ing on port 22.  This makes sense, since the docker container has a different identity than the host machine.
Is there a way to resolve this?

A:

The easiest (not sure if the cleanest, or best) would be to copy the host keys into the container as well.
