ansible-common

Ansible role for common configuration tasks on EL7 servers.

Requirements

Currently, the role only supports CentOS and Red Hat Enterprise Linux (RHEL) EL7 distribution flavors.

It also requires RHEL/CentOS 7.4 or higher since it provides a newer python-virtualenv package (1.10.1-4.el7+) which fixes compatibility with Python 3 (for more details, see: https://bugzilla.redhat.com/show_bug.cgi?id=1411685).

If you need support for other flavors, feel free to submit a pull request.
