Ansible 生成数字数组

Ansible 生成数字数组

我的目的是生成一个包含从 1 到 22 的数字的列表,为此我在下面编写了 Ansible 脚本。

- hosts: localhost
  gather_facts: no
  tasks:
    - name: Generate sequance
      set_fact:
        mysequence: "{{ item | list }}"
      with_sequence: start=1 end=22

    - debug: var=mysequence

当我运行代码时我得到了这个奇怪的结果

$ ansible-playbook test.yml

PLAY [localhost] **************************************************************************************************************************

TASK [Generate sequance] ******************************************************************************************************************
ok: [localhost] => (item=1)
ok: [localhost] => (item=2)
ok: [localhost] => (item=3)
ok: [localhost] => (item=4)
ok: [localhost] => (item=5)
ok: [localhost] => (item=6)
ok: [localhost] => (item=7)
ok: [localhost] => (item=8)
ok: [localhost] => (item=9)
ok: [localhost] => (item=10)
ok: [localhost] => (item=11)
ok: [localhost] => (item=12)
ok: [localhost] => (item=13)
ok: [localhost] => (item=14)
ok: [localhost] => (item=15)
ok: [localhost] => (item=16)
ok: [localhost] => (item=17)
ok: [localhost] => (item=18)
ok: [localhost] => (item=19)
ok: [localhost] => (item=20)
ok: [localhost] => (item=21)
ok: [localhost] => (item=22)

TASK [debug] ******************************************************************************************************************************
ok: [localhost] => {
    "mysequence": [
        "2",
        "2"
    ]
}

PLAY RECAP ********************************************************************************************************************************
localhost                  : ok=2    changed=0    unreachable=0    failed=0

我正在使用最新版本的 Ansible。任何帮助都非常感谢!


我需要此列表来完成另一项任务。以下是片段:

- name: Reboot 22 VMs
  vmware_guest:
    validate_certs: false
    hostname: x.x.x.x
    username: [email protected]
    password: PASSS
    datacenter: DC1
    folder: "DC1/vm/Pod-{{item[1]}}"
    name: "{{item[0]}}-Pod-{{item[1]}}"
    state: restarted
  delegate_to: localhost
  with_nested:
    - "{{myVarList}}"
    - [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22]

答案1

没有什么是诡异的在您的结果中:您设置了mysequence22 次,前 21 次迭代的值被覆盖,最后一个值是一个22转换为带过滤器的列表的字符串list。结果您得到了包含2和的双元素列表2

您希望任务看起来像这样:

- name: Generate sequance
  set_fact:
    mysequence: "{{ mysequence | default([]) + [item | int] }}"
  with_sequence: start=1 end=22

但您真正想要的是一种在 Jinja2 模板中生成整数列表的方法:

- set_fact:
    mysequence: "{{ range(1, 22 + 1) | list }}"
