Amazon ec2 库存中静态组和动态组的混合

我正在尝试将静态和动态（EC2）库存结合起来。有两个ec2实例：

• 可拆卸控制机
• 基于ami的主机

正在尝试从控制计算机ping'ami'主机。这是我的主机文件：

[local] 
localhost ansible_connection=local

[tag_Name_ami]

[tag_Name_redhat]

[amazon:children] 
tag_Name_ami 
tag_Name_redhat

要成功ping'ami'主机，我需要使用两个特定变量：

• ansible_ssh_用户：ec2用户（我的控制机器是ubuntu）
• ansible\u ssh\u private\u key\u文件：/home/ubuntu/.ssh/klucze.pem

试图通过在group_vars目录中创建文件来实现：

.
├── demo_setup.yml
├── ec2.ini
├── ec2.py
├── group_vars
│   ├── amazon.yml
│   ├── aws-redhats
│   ├── tag_Name_ami.yml
│   └── tag_Name_redhat.yml
├── hosts
├── hosts.bckp
└── host_vars

$ cat group_vars/tag_Name_ami.yml 
ansible_ssh_user: ec2-user
$ cat group_vars/amazon.yml 
ansible_ssh_private_key_file: /home/ubuntu/.ssh/klucze.pem

问题是ansible似乎只“看到”带有ansible\u ssh\u用户的标记\u Name\u ami.yml，而忽略了带有ansible\u ssh\u private\u key\u文件值的我的amazon.yml。一些输出如下：

$ ansible tag_Name_ami -i ec2.py -m ping -vvv

It is sometimes useful to re-run the command using -vvvv, which prints SSH debug output to help diagnose the issue.

$ ansible amazon -i ec2.py -m ping
No hosts matched
$ 

将我的静态主机文件与Web服务器组一起使用。剧本看起来像：

---
- hosts: amazon 
  remote_user: ec2-user
  tasks:
  - name: Execute ping
    ping:
...

将“amazon”作为主机值放入playbook返回错误：

PLAY [amazon] ***************************************************************** 
skipping: no hosts matched

---

还尝试使用“-i ec2.py”执行playbook，同样的错误

您可以在ec2主机上循环，并在playbook中设置变量

ansible\u ssh\u private\u key\u文件

- hosts: amazon
  gather_facts: false
  tasks:
    - set_fact:
        ansible_ssh_private_key_file: '/home/ubuntu/.ssh/klucze.pem'
...

---

谢谢你的回复。这是否意味着“全球”不可能实现这一目标？我想设置一次，然后忘记它，而无需在每个剧本中添加以下内容

PLAY [amazon] ***************************************************************** 
skipping: no hosts matched

- hosts: amazon
  gather_facts: false
  tasks:
    - set_fact:
        ansible_ssh_private_key_file: '/home/ubuntu/.ssh/klucze.pem'
