將 Ansible 與 AWS 動態清單 (ec2.py) 結合使用

Question

嘗試使用 ec2.py 使用靜態+動態主機文件。

我試過以下指南：

• https://aws.amazon.com/blogs/apn/getting-started-with-ansible-and-dynamic-amazon-ec2-inventory-management/
• http://docs.ansible.com/ansible/latest/intro_dynamic_inventory.html#static-groups-of-dynamic-groups

重要的是要說在下面運行它是有效的！

ansible -m ping tag_Ansible_Test

意思是 aws-cli、boto 和 ec2.py 已正確安裝並正常工作。

現在，在 hosts 文件中定義以下組（如文檔所述）時：

[tag_Ansible_Test]

[backend-test-group:children]
tag_Ansible_Test

---

ansible -m ping backend-test-group -vvvv

嘗試對組運行 ansible 命令時，出現以下錯誤：

ansible 2.4.0.0
  config file = /etc/ansible/ansible.cfg
  configured module search path = [u'/root/.ansible/plugins/modules', u'/usr/share/ansible/plugins/modules']
  ansible python module location = /usr/lib/python2.7/site-packages/ansible
  executable location = /bin/ansible
  python version = 2.7.5 (default, Nov 20 2015, 02:00:19) [GCC 4.8.5 20150623 (Red Hat 4.8.5-4)]
Using /etc/ansible/ansible.cfg as config file

 [WARNING]: No hosts matched, nothing to do

Loading callback plugin minimal of type stdout, v2.0 from /usr/lib/python2.7/site-packages/ansible/plugins/callback/__init__.pyc

我在這里缺少什么？

通過如下設置文件夾結構解決的問題：

/etc/ansible/combined
- hosts (the original file static+dynamic hosts file)
- ec2.py
- ec2.ini

然后，更改 ansible.cfg 中的inventory設置：

...
inventory       = /etc/ansible/combined
...
