问题描述
仅当当前剧本的主机不属于某个组时,我才希望能够执行ansible任务.用半伪代码:
I'd like to able to run an ansible task only if the host of the current playbook does not belong to a certain group. In semi pseudo code:
- name: my command
command: echo stuff
when: "if {{ ansible_hostname }} not in {{ ansible_current_groups }}"
我应该怎么做?
推荐答案
这是另一种方法:
- name: my command
command: echo stuff
when: "'groupname' not in group_names"
group_names
is a magic variable as documented here: https://docs.ansible.com/ansible/latest/user_guide/playbooks_variables.html#accessing-information-about-other-hosts-with-magic-variables :
group_names是当前主机所在的所有组的列表(数组).
group_names is a list (array) of all the groups the current host is in.
