我正在编写将我的 Web 应用程序部署到 EC2 实例的剧本。我一直在寻找已创建实例的公共 IP。
我正在尝试使用 捕获公共 IP {{ hostvars[groups['aws'][0]]['ansible_eth0']['ipv4']['address'] }}，但我得到的是私有 IP 172.31.93.XXX。
以下任务的输出是：
- debug: var=ansible_all_ipv4_addresses
TASK [debug] *******************************************************************
ok: [54.208.31.XX] => {
"ansible_all_ipv4_addresses": [
"172.31.93.XXX"
]
}
有没有办法使用主机的公共IP？
我将使用模块 ec2_facts ( https://docs.ansible.com/ansible/2.3/ec2_facts_module.html ) 收集 ec2 事实，该模块将从 AWS EC2 实例元数据 ( http://docs.aws.amazon.com/收集数据AWSEC2/latest/UserGuide/ec2-instance-metadata.html）。
然后我会使用事实ansible_ec2_public_ipv4来获取公共 IP。
以下是模块输出的示例：
[centos@ip-10-0-0-172 ~]$ ansible localhost -m ec2_facts
