AWS动态库存不会提取重复的主机名

Question

我使用Ansible inventory yaml文件获取正在运行的主机列表，但我只获得唯一的命名主机。正如您在AWS EC2中所看到的，我有三个服务器名为GamingServers，但我只得到其中一个主机。

​

​

当AWX运行脚本时，它只得到一个主机。我有14个主机，但有些是重复的名字。

即使标签名是重复的，我如何才能让所有正在运行的主机？

​

​

inventory.yml

plugin: aws_ec2
regions:
  - us-east-1
  - us-west-1
  - us-west-2
  - ap-south-1
filters:
  "instance-state-name": running
strict_permissions: False
hostnames:
  - tag:Name
keyed_groups:
- prefix: tag_Name_
  key: tags.Name
  separator: ""
compose:
  ansible_host: public_ip_address
# Can use IAM role in future to avoid IAM users and static passwords
#iam_role_arn: "asdfas"

Answer 1

这是由于使用

hostnames:
  - tag:Name

但是，在Ansible库存中，主机名是唯一的标识符。

因此，场景背后真正发生的是实例正在覆盖自身，因为它们具有相同的主机名。

如果您想保持将tag:Name作为主机名的可读性，并将这些多个实例包含在库存中，那么您可以在这里做的是将标签的主机名与唯一值(如主机的实例ID )组合在一起，如下所示：

hostnames:
  - name: 'instance-id'
    separator: '_'
    prefix: 'tag:Name'

这将给您提供主机名如下：

• GamingServer_i-05245d11820c11f4b
• GamingServer_i-01b11144ac8cec108
• GamingServer_i-031df0231c429149a
