# Dockerfile for building Ansible 1.9 image for CentOS 7, with as few additional software as possible.
#
# @see http://docs.ansible.com/intro_installation.html#latest-release-via-yum
#
# [NOTE] To fix the "sudo: sorry, you must have a tty to run sudo" issue,
#        we need to patch /etc/sudoers.
#        @see http://unix.stackexchange.com/questions/122616/why-do-i-need-a-tty-to-run-sudo-if-i-can-sudo-without-a-password
#        @see https://bugzilla.redhat.com/show_bug.cgi?id=1020147
#
# Version  1.0
#


# pull base image
FROM centos:centos7
