amazon-web-services - 使用 ansible 启动 aws ec2 实例的最佳方式

Question

我正在尝试在 Amazon AWS 上创建一个带有 ansible 的小型 webapp 基础设施，我想完成所有过程:启动实例、配置服务等，但我找不到合适的工具或模块来处理来自 ansible 的问题。主要是 EC2 启动。

非常感谢。

这是您问题的简短答案，如果您需要详细信息和完全自动化的角色，请告诉我。谢谢

先决条件 :

Ansible

Python boto 库

在环境设置中设置 AWS 访问 key 和 key
(最好在 ~./boto 内)

创建 EC2 实例:

为了创建 EC2 实例，请修改您可以在“vars”下的“ec2_launch.yml”文件中找到的这些参数:

地区 # 要在哪里启动实例，美国、澳大利亚、爱尔兰等

count # 要创建的实例数

一旦您提到了这些参数，请运行以下命令:

ansible-playbook -i hosts ec2_launch.yml

的内容|主持人 文件:

[local]
localhost

[webserver]

的内容| ec2_launch.yml 文件:
