amazon-web-services - 如何在AWS CDK中导入现有的VPC？

嗨，我在aws cdk上工作。我正在尝试获取现有的非默认vpc。我尝试了以下选项。

vpc = ec2.Vpc.from_lookup(self, id = "VPC", vpc_id='vpcid', vpc_name='vpc-dev')

这导致以下错误

[Error at /LocationCdkStack-cdkstack] Request has expired.
[Warning at /LocationCdkStack-cdkstack/TaskDef/mw-service] Proper policies need to be attached before pulling from ECR repository, or use 'fromEcrRepository'.
Found errors

我尝试的其他方法是

vpc = ec2.Vpc.from_vpc_attributes(self, 'VPC', vpc_id='vpc-839227e7', availability_zones=['ap-southeast-2a','ap-southeast-2b','ap-southeast-2c'])

这导致

[Error at /LocationCdkStack-cdkstack] Request has expired.
[Warning at /LocationCdkStack-cdkstack/TaskDef/mw-service] Proper policies need to be attached before pulling from ECR repository, or use 'fromEcrRepository'.
Found errors

我尝试的其他方法是
vpc = ec2.Vpc.from_lookup(self, id = "VPC", is_default=True)//这将获得默认的vpc，并且可以正常工作

有人可以帮我在AWS CDK中获得非默认VPC吗？任何帮助，将不胜感激。谢谢

最佳答案

看一看aws_cdk.aws_ec2 documentation和CDK Runtime Context。

用法:

# Example automatically generated. See https://github.com/aws/jsii/issues/826
from aws_cdk.core import App, Stack, Environment
from aws_cdk import aws_ec2 as ec2

# Information from environment is used to get context information
# so it has to be defined for the stack
stack = MyStack(
    app, "MyStack", env=Environment(account="account_id", region="region")
)

# Retrieve VPC information
vpc = ec2.Vpc.from_lookup(stack, "VPC",
    # This imports the default VPC but you can also
    # specify a 'vpcName' or 'tags'.
    is_default=True
)

更新相关示例:

vpc = ec2.Vpc.from_lookup(stack, "VPC",
    vpc_id = VPC_ID
)

使用 typescript 示例进行更新:

import ec2 = require('@aws-cdk/aws-ec2');
const getExistingVpc = ec2.Vpc.fromLookup(this, 'ImportVPC',{isDefault: false,vpcId: vpcId });
