Ansible: redefining default variables

№ 9131 В разделе "Администрирование" от August 23rd, 2018,

Variable kube_resolv_conf was defined as default value, but in deploying process you need to change it depend on your OS.

- name: Check OS type and version before resolv.conf location definition
    kube_resolv_conf: '/run/systemd/resolve/resolv.conf'
  when: ansible_distribution == 'Ubuntu' and ansible_distribution_release == 'bionic'

ansible_distribution and ansible_distribution_release is a magic variables, defined after gathering facts about target host.
