尝试运行Lambda函数来调用ssm并定义EC2标签以将其推送到多个实例上

如何解决尝试运行Lambda函数来调用ssm并定义EC2标签以将其推送到多个实例上

尝试使用以下脚本在Lambda函数上运行以调用SSM并定义EC2标签以将其推送到多个实例上。尝试执行时出现以下错误。我刚刚开始学习编写脚本并第一次使用aws lambda。请帮我修复。

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：

Response:
{
  "errorMessage": "Syntax error in module 'lambda_function': invalid syntax (lambda_function.py,line 7)","errorType": "Runtime.UserCodeSyntaxError","stackTrace": [
    "  File \"/var/task/lambda_function.py\" Line 7\n            Name = 'tag:Product',\n"
  ]
}

解决方法

有几个问题：

缩进错误。

在python中没有这样的东西

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

也许您是指字典？：

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

InstanceIds=instances应该是字符串列表，而不是'filters'的原义字符串。

代码修复的结束时间如下：

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)
