Ansible任务将在＆＃34; server_1＆＃34;以外的主机上运行或＆＃34; server_2＆＃34;

Question

我希望能够仅在不匹配＆＃34; server_1＆＃34;的主机上运行ansible任务。或＆＃34; server_2＆＃34;。

半伪代码：

- name: Set localtime
  file: src=/usr/share/zoneinfo/UTC
        dest=/etc/localtime
        state=link
  when: only when hostname is NOT "server_1" or "server_2"

Answer 1

比较主机名：

when: ansible_hostname not in ['server_1', 'server_2']

比较库存别名：

when: inventory_hostname not in ['server_1', 'server_2']

Answer 2

你可以试试这个：

- name: Set localtime
  file: src=/usr/share/zoneinfo/UTC
        dest=/etc/localtime
        state=link
  when: ansible_hostname not in [server_1', 'server_2']
