要为AWS SAM Lambda授权者提供互联网访问,可以使用以下解决方法:
Resources:
MyFunction:
Type: AWS::Serverless::Function
Properties:
CodeUri: ./src
Handler: index.handler
Runtime: nodejs14.x
Policies:
- AWSLambdaBasicExecutionRole
VpcConfig:
SecurityGroupIds:
- sg-xxxxx
SubnetIds:
- subnet-xxxxx
VpcId: vpc-xxxxx
Events:
MyApi:
Type: Api
Properties:
Path: /my-api
Method: get
在这个示例中,Lambda函数被配置为使用VPC,因此它将无法直接访问互联网。但是,由于它具有AWSLambdaBasicExecutionRole
策略,它仍然具有基本的云服务访问权限。
Resources:
MyFunction:
Type: AWS::Serverless::Function
Properties:
CodeUri: ./src
Handler: index.handler
Runtime: nodejs14.x
Policies:
- AWSLambdaBasicExecutionRole
VpcConfig:
SecurityGroupIds:
- sg-xxxxx
SubnetIds:
- subnet-xxxxx
VpcId: vpc-xxxxx
Events:
MyApi:
Type: Api
Properties:
Path: /my-api
Method: get
MyNatGateway:
Type: AWS::EC2::NatGateway
Properties:
AllocationId:
SubnetId: subnet-xxxxx
MyRouteTable:
Type: AWS::EC2::RouteTable
Properties:
VpcId: vpc-xxxxx
MyRoute:
Type: AWS::EC2::Route
DependsOn: MyNatGateway
Properties:
RouteTableId: !Ref MyRouteTable
DestinationCidrBlock: 0.0.0.0/0
NatGatewayId: !Ref MyNatGateway
MySubnetRouteTableAssociation:
Type: AWS::EC2::SubnetRouteTableAssociation
Properties:
RouteTableId: !Ref MyRouteTable
SubnetId: subnet-xxxxx
在这个示例中,我们创建了一个NAT网关并将其与Lambda函数的VPC相关联。然后,我们在VPC的路由表中创建了一个默认路由,将所有流量引导到NAT网关。这样,Lambda函数就可以通过NAT网关访问互联网。
请注意,以上示例仅供参考,实际配置可能因您的特定环境而有所不同。请根据您的需求修改示例模板。
