本文记录使用Python脚本和Boto3按名字搜索AWS Image并返回AWS Image的相关参数。

问题及解决

记得操作之前拿到相应的权限：

export AWS_ACCESS_KEY_ID="xxxxxxxxxxxxxxxxxxxxxxxxxx"

export AWS_SECRET_ACCESS_KEY="yyyyyyyyyyyyyyyyyyyyyyyyyyyy"

export AWS_SESSION_TOKEN="zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz"

使用以下Python脚本：

#!/bin/python
import json
import boto3

def get_ec2_image():
    ec2_client = boto3.client('ec2')
    describe_images_response = ec2_client.describe_images(
        DryRun=False,
        Owners=[
            'amazon',
        ],
        Filters=[
            {
                'Name': 'name',
                'Values': [
                    'amzn2-ami-ecs-hvm-2.0.20231204-x86_64-ebs',
                ]
            },
        ]
    )
    print("image return: "+ json.dumps(describe_images_response, indent = 4))

以上函数会返回镜像的相关参数，例如使用ImageId来用于创建EC2资源，以下的返回为"ImageId": "ami-0b00532b21d4d18e4" 为了让Json输出更美观，使用了indent = 4这个参数，显示效果如下：

image return: {
    "Images": [
