ansible - 如何有条件地使用状态？

Question

我在剧本中有一个blockinfile，它应该存在于不依赖于先前设置的变量的值。暴力解决方案是

  - name: shorewall rules
    blockinfile:
      dest: /etc/shorewall/rules
      state: present
      block: |
        # settings for machine {{ machine }}
        # outgoing internet
        ACCEPT {{ machine }} int
        # more here
      when: active == "y"

  - name: shorewall rules
    blockinfile:
      dest: /etc/shorewall/rules
      state: absent
      block: |
        # settings for machine {{ machine }}
        # outgoing internet
        ACCEPT {{ machine }} int
        # more here
      when: active == "n"

有没有办法在 state 中设置条件？

state: present if active == "y" else absent

Answer 1

你可以这样做:

state: "{{ 'present' if active == 'y' else 'absent' }}"
