Fail to build keystone ubuntu binary docker image

When building ubuntu binary docker image for keystone, encounter following error.

INFO:kolla.image.build.keystone-base:Step 4 : RUN mkdir -p /var/www/cgi-bin/keystone && cp -a /usr/share/keystone/wsgi.py /var/www/cgi-bin/keystone/main && cp -a /usr/share/keystone/w

Is the apache vhost keystone.conf supposed to be there in the first place?
