While my services are used by fewer people (and fewer in number), this
is where my most recent server rebuild took me.  i have been trying to
use containers exclusively as it reduces the surface I have to
maintain, assuming I can't find a trusted container source.
Additionally, I am thinking ahead to the future where I hope that the
OS will become available in a container-runner form where the surface
is further reduced.  My needs don't rise to the level of an OpenShift,
but it sounds like yours may, especially given the WP instances.
