只需使用 Python API Boto 创建 AWS 实例？

Question

我在互联网上寻找了不同的方法来做这件事，但我似乎可以得到任何工作。我知道这可能是一个简单的代码块，可以做到这一点，但我就是想不通。如果您能分享一些代码，我将不胜感激，这样我就可以完成这项任务。感谢您的宝贵时间。

您可以尝试以下代码开始。请注意，只有 AMI ID, MinCount & Max Count 是启动 EC2 实例所需的强制参数，其他值（如 Subnet ID, Key Pair, Instance Size etc.）也可以为实时场景指定。

import boto3

ec2 = boto3.session.Session(aws_access_key_id='abcedfgh', aws_secret_access_key='abcedfgh', region_name='us-east-1')

response = client.run_instances(
    ImageId='ami-12345678',
    MinCount=1,
    MaxCount=1
)

print response

boto3 - EC2 运行实例文档 [http://boto3.readthedocs.org/en/latest/reference/services/ec2.html#EC2.Client.run_instances] 中提供了相同输入的完整存根。

response = client.run_instances(
    DryRun=True|False,

    MinCount=123,
    MaxCount=123,
