In the web console I've choosed rails-postgresql-example
the postgresql start correctly but when I try to run the rails build
oc start-build rails-example -n <project>
I receive "Error from server: imageStream "ruby" not found"
Instead if i try to install wordpress with this guide:https://github.com/openshift/training/blob/master/beta-4-setup.md#arbitrary-docker-image-builder
$ oc new-app -l name=wordpress https://github.com/openshift/centos7-wordpress.git
A build was created - you can run `oc start-build centos7-wordpress` to start it.
Service "centos7-wordpress" created at <ip_redacted> with port mappings 22->22, 80->80.
$ oc start-build centos7-wordpress
Error from server: imageStreamTag "centos:centos7" not found
