			`- name: Cordon node`
Add graceful upgrade process Based on #718 introduced by rsmitty. Includes all roles and all options to support deployment of new hosts in case they were added to inventory. Main difference here is that master role is evaluated first so that master components get upgraded first. Fixes #694 2017-02-15 00:08:44 +08:00			`command: "{{ bin_dir }}/kubectl cordon {{ ansible_hostname }}"`
