Insecure instructions in CDK IG (gpgcheck)

Section "5.2.1.1. Registering a Red Hat Enterprise Linux System and Enabling Repositories" notes that to install Vagrant, you must use a CentOS repo over an insecure protocol (HTTP) and on top of that disable GPG check:

https://access.redhat.com/documentation/en/red-hat-container-development-kit/2.2/paged/installation-guide/chapter-5-installing-container-development-kit-on-red-hat-enterprise-linux#registering_a_red_hat_enterprise_linux_system_and_enabling_repositories

This is strange since the packages are definitely signed:

$ rpm -qpi http://mirror.centos.org/centos-7/7/sclo/x86_64/sclo/vagrant1/sclo-vagrant1-vagrant-1.8.1-7.el7.noarch.rpm 2> /dev/null |grep -i Signature
Signature : RSA/SHA1, Wed 24 Aug 2016 03:40:26 PM CEST, Key ID 4eb84e71f2ee9d55

Can the docs be corrected please to remove the step to disable 'gpgcheck'? Also, maybe it's worth researching if there is a way to get the package over HTTPS.
