问题描述
我在ansible的main.yml var文件中添加了两种服务器主机名:
I have two type of server host names added in the ansible main.yml var file:
main.yml文件:
main.yml file:
foo_server1: 10.10.1.1
foo_server2: 10.10.1.2
bar_server1: 192.168.1.3
bar_server2: 192.168.1.4
bar_server3: 192.168.1.5
我有一本有趣的剧本,它基本上在foo_server1上运行,并且一次初始化/格式化列表中的所有其他服务器-从foo_server2开始,然后是bar_server1,bar_server2等...
I am having an ansible playbook which essentially runs on foo_server1 and initializes/formats all other servers in the list one at a time - starting with foo_server2 then bar_server1, bar_server2 and so on...

- name: Reading variables from var files
hosts: localhost
connection: local
vars_files:
- main.yml
tasks:
- name: Initialize foo server2
command: initialize --host1 {{foo_server1}} to --host2 {{foo_server2}}
- name: Initialize bar server1
command: initialize --host1 {{foo_server1}} to --host2 {{bar_server1}}
- name: Initialize bar server2
command: initialize --host1 {{foo_server1}} to --host2 {{bar_server2}}
- name: Initialize bar server3
command: initialize --host1 {{foo_server1}} to --host2 {{bar_server3}}
我不想在剧本中为每台服务器添加多行,而是想遍历变量文件中的主机名.我不确定如何完成此操作..我正在尝试遍历主机名..尝试了以下操作,但由于我获得了未定义的变量名,所以运气不佳.
I dont want to add multiple lines in the playbook for each server rather wants to loop over the host names from the variable file. I am not sure how i would get this done..i am trying to loop over the hostname.. tried something below but no luck as i am getting undefined variable name..

server_list:
foo_server1: 10.10.1.1
foo_server2: 10.10.1.2
bar_server1: 192.168.1.3
bar_server2: 192.168.1.4
bar_server3: 192.168.1.5
Ansible剧本...
Ansible playbook...

- hosts: localhost
gather_facts: no
vars_files:
- input.yml
tasks:
- name: Enable replication
local_action: shell initialize --host1 {{item.foo_server1}} --host2 {{item.foo_server2}}
with_items:
- "{{ server_list }}"
有人可以建议我如何在多台服务器上运行同一命令.非常感谢所提供的任何帮助..
Can some one please suggest how can i run the same command on multiple servers. Would appreciate any help offered..
推荐答案
以下是您的示例:
---
- hosts: localhost
gather_facts: no
vars:
servers:
foo_server1: 10.10.1.1
foo_server2: 10.10.1.2
bar_server1: 192.168.1.3
bar_server2: 192.168.1.4
bar_server3: 192.168.1.5
tasks:
- debug:
msg: shell initialize --host1 {{ servers.foo_server1 }} --host2 {{ item.value }}
when: item.key != 'foo_server1'
with_dict: "{{ servers }}"
