Offline Install of Foreman to RHEL 7.2

I am new to both linux and Foreman. Attempting to do an install with no
internet connection and cannot seem to find any documentation to support
this. Thanks for any assist!

It appears I was able to install Puppet and the epel repository. But when
attempting to execute <yum -y install foreman_release.rpm> I get the
following error. Also attempted using localinstall with the same result.

One of the configured repositories failed (Unknown), and yum doesn't have
enough cached data to continue.

Cannot retrieve metalink for repository: epel/x86_64. Please verify its
path and try again
