使用 ansible 从多个 citrix hypervisors vms 获取 IP 地址列表
Get list of ip addesses from multiple citrix hypervisors vm's using ansible
我正在使用 ansible 和 xenserver_guest_info 模块从我的 citrix hypervisor 服务器上的多个虚拟机创建一个 IP 地址列表。目前我只想打印一个 ip 列表,但将这些 ip 存储在一个 ansible 列表中会更好。我计划使用 ansible 在所有这些 vm 上循环遍历此 ip 列表和 运行 命令。
这是我目前的 ansible 剧本。它循环遍历 xenserver 模块 returns 的字典输出,试图提取 ip 地址。:
- name: Manage VMs
connection: local
hosts: localhost
# Hypervisor server info from vars file
vars_files:
- xen_vars.yml
tasks:
- name: Gather facts
xenserver_guest_info:
hostname: "{{ xen_address}}"
username: "{{ admin_username }}"
password: "{{ admin_password }}"
name: "{{ item }}"
loop: "{{ xen_machines }}"
register: facts
# - name: Get IP's of VM's
- debug:
msg: "{{item.instance.networks}}"
loop: "{{facts.results}}"
它会在我的服务器上给出两个虚拟机的列表时产生以下输出:

我尝试只访问 ip,但它一直无法正常工作,因为它存储在列表中。
同样,我的最终目标是让 ansible 吐出一个 ip 列表,如下所示:
192.168.0.2
192.168.0.3
或者更好的是将它们存储在一个 ansible 列表中供以后使用。任何帮助将不胜感激。
如果您遇到的唯一真正问题是 IP 在列表中,并且您知道(由于您配置 VM 的方式)列表总是只有一个条目,那么只需获取第一项在列表中:
item.instance.networks[0].ip
如果你想使用这些 IP 地址在虚拟机上做一些 Ansible 工作,我建议你使用 add_host
为你的剧本中的第二个游戏构建一个新的清单:
