尝试 运行 一个 Lambda 函数来调用 ssm 并定义一个 EC2 标签以将其推送到多个实例

Question

尝试 运行 一个 Lambda 函数来调用 SSM 并定义一个 EC2 标签以使用以下脚本在多个实例上推送相同的标签。尝试执行时出现以下错误。我刚开始学习编写脚本并第一次使用 aws lambda。请帮我修复一下。

import boto3
ssm = boto3.client('ssm')
ec2 = boto3.resource('ec2')

def lambda_handler(event, context):
    filters = (
        Name = 'tag:Product',
        Values = ['Essay']
    )
instances = ('filters')
response = ssm.send_command(
    InstanceIds=instances,
    DocumentName='xxxxxxxxxxxxx',
    DocumentVersion='$DEFAULT',
    DocumentHash='916fdxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxdcdbe7940',
    DocumentHashType='Sha256'
    )
print(response)

错误：

  "errorType": "Runtime.UserCodeSyntaxError",
  "stackTrace": [

有几个问题：

缩进错误。

python中没有

    filters = (
        Name = 'tag:Product',
        Values = ['Essay']
    )

也许你指的是字典？:

    filters = {
        'Name':'tag:Product',
        'Values': ['Essay']
    }

InstanceIds=instances 应该是字符串列表，而不是 'filters'.

的文字字符串

修复代码的结尾如下：

import boto3

ssm = boto3.client('ssm')
ec2 = boto3.resource('ec2')

def lambda_handler(event, context):
    filters = [{
        'Name':'tag:Product',
        'Values': ['Essay']
    }]
    instances = [instance.id for instance in ec2.instances.filter(Filters = filters)]
    
    response = ssm.send_command(
        InstanceIds=instances,
        DocumentName='xxxxxxxxxxxxx',
        DocumentVersion='$DEFAULT',
        DocumentHash='916fdxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxdcdbe7940',
        DocumentHashType='Sha256'
        )
    print(response)
