1 # Dockerfile for building Ansible image from source for CentOS 6, with as few additional software as possible.
3 # @see http://docs.ansible.com/ansible/intro_installation.html#running-from-source
5 # [NOTE] To fix the "sudo: sorry, you must have a tty to run sudo" issue,
6 # we need to patch /etc/sudoers.
7 # @see http://unix.stackexchange.com/questions/122616/why-do-i-need-a-tty-to-run-sudo-if-i-can-sudo-without-a-password
8 # @see https://bugzilla.redhat.com/show_bug.cgi?id=1020147
