我无法让我的 Ansible 游戏hosts与为我的动态清单返回的 AWS 动态组匹配。让我们分解这个问题。

鉴于此输出ec2.py --list：

$ ./devops/inventories/dynamic/ec2.py  --list

  "_meta": {
    "hostvars": {
      "54.37.213.132": {

        "ec2_vpc_id": "vpc-5fe8ae3a"
      }
    }
  }, 
  "ec2": [
    "54.37.213.132"
  ], 
  "tag_Environment_v1": [
    "54.37.213.132"
  ], 
  "tag_Name_peaker-v1-ec2": [
    "54.37.213.132"
  ], 
  "us-west-2": [
    "54.37.213.132"
  ]
}

我应该能够编写一个匹配一些回来的组的剧本：

---
# playbook
- name: create s3 bucket with policy
  hosts: localhost
  gather_facts: yes
  tasks:
    - name: s3
      s3:
        bucket: "fake"
        region: "us-west-2"
        mode: create
        permission: "public-read-write"
      register: s3_output
    - debug: msg="{{ s3_output }}"

- name: test on remote machine
  hosts: ec2
  gather_facts: yes
  tasks:
    - name: test on remote machine
      file:
        dest: "/home/ec2-user/test/"
        owner: ec2-user
        group: ec2-user
        mode: 0700
        state: directory
      become: yes
      become_user: ec2-user

但是，当我--list-hosts匹配这些播放时，很明显播放主机没有匹配任何返回的内容：

$ ansible-playbook -i devops/inventories/dynamic/ec2/ec2.py  devops/build_and_bundle_example.yml --ask-vault-pass --list-hosts
Vault password:
 [WARNING]: provided hosts list is empty, only localhost is available

playbook: devops/build_and_bundle_example.yml

  play #1 (localhost): create s3 bucket with policy TAGS: []
    pattern: [u'localhost']
    hosts (1):
      localhost

  play #2 (ec2): test on remote machine TAGS: []
    pattern: [u'ec2']
    hosts (0):

快速修复您正在做的事情：

  • 将hosts: localhost您的剧本更改为hosts: all

如果你要保留hosts: localhost在你的剧本中，它永远不会只使用动态库存......

如果是这样，您必须结合动态和静态库存。创建带有路径的文件./devops/inventories/dynamic/static.ini（与 ec2.py 和 ec2.ini 在同一级别）并放置以下内容：

[localhost]
localhost

[ec2_tag_Name_peaker_v1_ec2]

[aws-hosts:children]
localhost
ec2_tag_Name_peaker_v1_ec2

之后，您将能够运行快速检查：

ansible -i devops/inventories/dynamic/ec2 aws-hosts -m ping

和你的剧本本身：

ansible-playbook -i devops/inventories/dynamic/ec2 \
    devops/build_and_bundle_example.yml --ask-vault-pass

注意： devops/inventories/dynamic/ec2是文件夹的路径，但它会自动解析为具有aws-hosts组名访问权限的混合动态和静态清单。

事实上，这并不是库存的最佳用途。但重要的是要理解，通过结合动态和静态清单，您只是为特定的动态主机附加新的组名

ansible -i devops/inventories/dynamic/ec2 all -m debug \
    -a "var=hostvars[inventory_hostname].group_names"
