Xibo install with defaults - apache not serving cms folder

With a centos 7 host, docker (ce) and docker-compose installed, xibo install seems to work with xmr, web, and db containers started, and web container handling web requests on port 80. Xibo and not not handling port 80.

But web container responds to localhost (and hostname) request with an index file in web container /var/www/localhost/htdocs instead of /var/www/cms/web

The index file just displays, “It works!” instead of the login screen.
Is there something I should minimally do beyond defaults to get the login screen?

Learned the problem was centos7 xfs filesystem without d_type feature turned on as required by docker.
