Group_by主机变量

Question

如何缩短此代码，以便在我按主机分组时不会重复？而不是重复rhel5，rhel6和rhel7块。我试过with_items但没有运气？

---
- hosts: "{{hosts}}"
  remote_user: root
  tasks:
    - group_by: key=rhel{{ansible_distribution_major_version}}    
- hosts: rhel5
  tasks:
    - debug: msg="{{ansible_distribution}} {{ansible_distribution_release}} {{ansible_distribution_version}}"

- hosts: rhel6
  tasks:
    - debug: msg="{{ansible_distribution}} {{ansible_distribution_release}} {{ansible_distribution_version}}"

- hosts: rhel7
  tasks:
    - debug: msg="{{ansible_distribution}} {{ansible_distribution_release}} {{ansible_distribution_version}}"

Answer 1

您可以使用patterns：

---
- hosts: "{{hosts}}"
  remote_user: root
  tasks:
    - group_by: key=rhel{{ansible_distribution_major_version}}    

- hosts: rhel5:rhel6:rhel7
  tasks:
    - debug: msg="{{ansible_distribution}} {{ansible_distribution_release}} {{ansible_distribution_version}}"

如果你需要除了某些东西，你可以使用：

- hosts: rhel*:!rhel4
