Question

我无法让我的Ansible play String与我的动态广告资源回来的AWS动态群组相匹配。让我们打破这个问题。

鉴于hosts的输出：

ec2.py --list

我应该能够写一个与回来的一些小组相匹配的剧本：

$ ./devops/inventories/dynamic/ec2.py  --list
{
  "_meta": {
    "hostvars": {
      "54.37.213.132": {

        "ec2_requester_id": "", 
        "ec2_root_device_name": "/dev/xvda", 
        "ec2_root_device_type": "ebs",

    }
  },

  ],

    "54.37.213.132"
  ], 
  "us-west-2": [
    "54.37.213.132"
  ]
}

但是，当我--- # 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匹配这些播放时，很明显播放主机不匹配任何内容：

--list-hosts

快速解决您正在做的事情：

将您的剧本中的hosts: localhost更改为hosts: all

如果您要将hosts: localhost保留在游戏手册中，那么它将永远无法使用动态广告资源...

如果是这样， - 你必须结合动态＆amp;静态库存。创建路径为./devops/inventories/dynamic/static.ini的文件（与ec2.py和ec2.ini位于同一级别）并放置此内容：

[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是该文件夹的路径，但它会自动解析为具有aws-hosts群组名称访问权限的混合动态和静态广告资源。

事实上，这不是库存的最佳用途。但重要的是要理解，通过组合动态和静态库存，您只需为特定动态主机添加新的组名

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

Ansbile AWS动态库存组无法匹配播放主机
