我有以下代码。
from aws_cdk import (
aws_ec2 as ec2,
core,
)
class MyVpcStack(core.Stack):
def __init__(self, scope: core.Construct, id: str, **kwargs) -> None:
super().__init__(scope, id, **kwargs)
# The code that defines your stack goes here
vpc = ec2.Vpc(
self, 'MyVpc',
cidr='10.10.10.0/23',
max_azs=2
)
dhcp_options = ec2.CfnDHCPOptions(
self, 'MyDhcpOptions',
domain_name='aws-prod.mydomain.com',
domain_name_servers=['10.1.1.5','10.2.1.5'],
ntp_servers=['10.1.1.250','10.2.1.250'],
)
dhcp_options_associations = ec2.CfnVPCDHCPOptionsAssociation(
self, 'MyDhcpOptionsAssociation',
dhcp_options_id=dhcp_options.logical_id,
vpc_id=vpc.vpc_id
)
它产生了 VPCDHCPOptionsAssociation
属性不正确,CloudFormation 模板中的此部分是这样的。
MyDhcpOptionsAssociation:
Type: AWS::EC2::VPCDHCPOptionsAssociation
Properties:
DhcpOptionsId: MyDhcpOptions
VpcId:
Ref: myvpcAB8B6A91
我需要CloudFormation模板中的这部分是这样的(正确的)。
MyDhcpOptionsAssociation:
Type: AWS::EC2::VPCDHCPOptionsAssociation
Properties:
DhcpOptionsId:
Ref: MyDhcpOptions
VpcId:
Ref: myvpcAB8B6A91
如果我在CloudFormation模板中使用 dhcp_options_id=dhcp_options.id
,我得到的错误是 AttributeError: 'CfnDHCPOptions' object has no attribute 'id'
.
如果我使用 dhcp_options_id=dhcp_options.dhcp_options_id
,我得到的错误是 AttributeError: 'CfnDHCPOptions' object has no attribute 'dhcp_options_id'
.
这里是CDK API的参考。https:/docs.aws.amazon.comcdkapilatestpythonaws_cdk.aws_ec2CfnVPCDHCPOptionsAssociation.html。
我找到了。它必须是 .ref
但与其他资源属性不一致。
dhcp_options_associations = ec2.CfnVPCDHCPOptionsAssociation(
self, 'MyDhcpOptionsAssociation',
dhcp_options_id=dhcp_options.ref,
vpc_id=vpc.vpc_id
)
