Greetings.

Just a note for anyone looking for ansible in epel7.

It’s been retired there because with the release of RHEL 7.4 it’s now
int the rhel-extras channel.

https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html-single/7.4_Release_Notes/index.html#technology_previews_red_hat_enterprise_linux_system_roles_powered_by_ansible

Accordingly, you can get ansible now from rhel extras channel, or CentOS
extras repo.

You can also get ansible rpms now from
http://releases.ansible.com/ansible/rpm/

Note that ansible continues to be available from epel6.
