我需要使用两台主机中的一台作为变量。我确实有
inventory_hostname_short
,但我需要一个完整的主机作为变量。目前,为了进行测试,我正在使用硬编码值。我的剧本将同时在两台主机上运行,那么我如何识别完整的主机名并将其存储为变量?
host_1_full = 123.abc.de.com
host_2_full = 345.abc.de.com
以上都是主持人,我确实有
---
- name: Ansible Script
hosts: all
vars:
host1_short : '123'
host2_short : '345'
tasks:
- name: set host
set_fact:
host1_full: "{{inventory_hostname}}"
when: inventory_hostname_short == host1_short
- name: print info
debug:
msg: "host - {{host1_full}}"
- name: block1
block:
- name:running PS1 file
win_shell: "script.ps1"
register: host1_output
when: inventory_hostname_short == host1_short
- name: block2
block:
- name: set host
set_fact:
IN_PARA: "{{ hostvars[host1_full]['host1_output']['stdout']}}"
- name:running PS1 file
win_shell: "main.ps1 -paramater {{ IN_PARA }}"
register: output
when: inventory_hostname_short == host2_short
从不同主机访问任何文件需要完整的主机名。我怎样才能获得完整的主机名?
鉴于以下情况
inventories/test_inventory.yml
---
all:
hosts:
123.abc.de.com:
345.abc.de.com:
ansible 将自动在
inventory_hostname
中提供所需的结果,如以下 test.yml
剧本所示
---
- name: Print long and short inventory name
hosts: all
gather_facts: false
tasks:
- name: print info
ansible.builtin.debug:
msg: "Host full name is {{ inventory_hostname }}. Short name is {{ inventory_hostname_short }}"
给出:
$ ansible-playbook -i inventories/test_inventory.yml test.yml
PLAY [print long and short inventory name] *********************************************************************************************************************************************************************************************
TASK [print info] **********************************************************************************************************************************************************************************************************************
ok: [345.abc.de.com] => {
"msg": "Host full name is 345.abc.de.com. Short name is 345"
}
ok: [123.abc.de.com] => {
"msg": "Host full name is 123.abc.de.com. Short name is 123"
}
PLAY RECAP *****************************************************************************************************************************************************************************************************************************
123.abc.de.com : ok=1 changed=0 unreachable=0 failed=0 skipped=0 rescued=0 ignored=0
345.abc.de.com : ok=1 changed=0 unreachable=0 failed=0 skipped=0 rescued=0 ignored=0
如前所述,
ansible_hostname
和 ansible_fqdn
是有关库存中主机的自动事实。但是,您的要求有点独特。因此,我们可能必须应用一种独特的方法来实现这一目标。像这样的怎么样?
考虑如下示例库存:
---
all:
hosts:
192.168.1.101: # 123.abc.de.com
192.168.1.102: # 345.abc.de.com
我们可以玩这样的游戏:
- hosts: all
vars:
host1_short: 123
host2_short: 345
tasks:
- command: "hostname -f"
register: result
- block:
- set_fact:
host1_full: "{{ result.stdout }}"
- debug:
msg: "Host1 fullname: {{ host1_full }}"
when: host1_short in result.stdout
