我正在使用模块csv-source-of-truth（https://github.com/joelwking/csv-source-of-truth）从csv文件获取IP和OS信息。我能够将这些信息注册到vsheet中，并使用debug，可以看到可以遍历vsheet的内容。
但是，当我使用ios_command并尝试遍历vsheet时，似乎卡在了vsheet的第一项。
这是Inventory.csv文件的内容：
192.168.68.201，ios
192.168.68.202，ios
代码：
---
- hosts: localhost
gather_facts: false
tasks:
- name: Block
block:

csv_to_facts:
src: '{{playbook_dir}}/NEW/Inventory.csv'
vsheets:

- OS
- debug:
msg: '{{item.IP}}'
loop: '{{INFO}}'
- name: Show Version
vars:
ansible_host: '{{item.IP}}'
ansible_network_os: '{{item.OS}}'
ansible_user: cisco
ansible_ssh_pass: cisco
ansible_connection: network_cli
ansible_become: yes
ansible_become_method: enable
ios_command:
commands: show version
register: output
loop: '{{INFO}}'
- name: Show the output of looped Show Version
debug:
var: output
- name: Show just the stdout_lines
debug:
var: output.results.{{item}}.stdout_lines
with_sequence: "0-{{output|length - 2}}"
当您查看正常运行时间信息时，您会在输出中注意到它仅具有R1的结果。即R1的正常运行时间如此。

尝试创建库存
- name: Create inventory
add_host:
hostname: '{{ item.IP }}'
groups: temp_group_01
ansible_network_os: '{{ item.OS }}'
ansible_user: cisco
ansible_ssh_pass: cisco
ansible_connection: network_cli
ansible_become: yes
ansible_become_method: enable
loop: '{{ INFO }}'
并委托给主机
- name: Show Version
ios_command:
commands: show version
register: output
delegate_to: '{{ item }}'
loop: '{{ groups['temp_group_01'] }}'
说明
从下面的游戏中可以看出，该连接未遵循更改的 ansible_host ，并继续使用循环中的第一项。
- hosts: test_01
tasks:
- command: hostname
register: result
vars:
ansible_host: "{{ item }}"
loop:
- test_02
- test_03
- debug:
msg: "{{ result.results|map(attribute='stdout')|list }}"
给予
TASK [command] ******************************************************************************
changed: [test_01] => (item=test_02)
changed: [test_01] => (item=test_03)
TASK [debug] ********************************************************************************
ok: [test_01] => {
"msg": [
"test_02",
"test_02"
]
}
此行为很可能是由连接插件引起的，因为 vars 可以正常工作。下面的游戏
- hosts: test_01
tasks:
- command: echo "{{ ansible_host }}"
register: result
vars:
ansible_host: "{{ item }}"
loop:
- test_02
- test_03
- debug:
msg: "{{ result.results|map(attribute='stdout')|list }}"
给予
TASK [command] ******************************************************************************
changed: [test_01] => (item=test_02)
changed: [test_01] => (item=test_03)
TASK [debug] ********************************************************************************
ok: [test_01] => {
"msg": [
"test_02",
"test_03"
]
}
因此，不可能循环 ansible_host 。相反，应使用 delegate_to 。
