摘要
我正在尝试使用 CDK 在 AWS 上部署 Redis ElastiCache 集群。
出于安全原因，我希望集群位于 VPC 内。
我的代码(参见上文)定义了一个 VPC、一个安全组、一个缓存子网组(链接到 vpc 私有(private)子网)和缓存集群(链接到缓存子网组和安全组)。
使用cdk部署，部署进展顺利，直到我收到此错误:
ACL_redis (ACLredis) Subnet group [default] belongs to a different VPC [vpc-326ce55b] than [vpc-0c45b593f3a5fdc4d] (Service: AmazonElastiCache; Status Code: 400; Error Code: InvalidParameterCombination; Request ID: 901398f4-c355-418d-921b-65e6c52dfe3a)
我尝试过的
禁用回滚时，缓存集群似乎是在该区域的默认 VPC 中创建的，而不是在我的堆栈中定义的 VPC 中创建的。 我不明白为什么 Cloud Formation 会这样做，因为安全组和缓存子网组都链接到堆栈的 VPC。
根本没有提及区域默认 VPC。
一些代码
这是CDK代码
from aws_cdk import (
core,
aws_stepfunctions,
aws_lambda,
aws_stepfunctions_tasks,
aws_sqs,
aws_elasticache,
aws_ec2,
)
PROJECT_CODE = 'ACL'
class AclAwsCdkLearningStack(core.Stack):
def __init__(self, scope: core.Construct, id: str, **kwargs) -> None:
super().__init__(scope, id, **kwargs)
vpc = aws_ec2.Vpc(self, f"{PROJECT_CODE}_vpc",
cidr="10.0.0.0/16"
)
security_group = aws_ec2.SecurityGroup(
scope=self,
id=f"{PROJECT_CODE}_security_group",
vpc=vpc,
)
private_subnets_ids = [ps.subnet_id for ps in vpc.private_subnets]
cache_subnet_group = aws_elasticache.CfnSubnetGroup(
scope=self,
id=f"{PROJECT_CODE}_cache_subnet_group",
subnet_ids=private_subnets_ids, # todo: add list of subnet ids here
description="subnet group for redis",
)
redis_cluster = aws_elasticache.CfnCacheCluster(
scope=self,
id=f"{PROJECT_CODE}_redis",
engine="redis",
cache_node_type="cache.t2.small",
num_cache_nodes=1,
cache_subnet_group_name=cache_subnet_group.cache_subnet_group_name,
vpc_security_group_ids=[security_group.security_group_id],
)
redis_cluster.add_depends_on(cache_subnet_group)
以下是生成的 JSON CloudFormation 代码:

\_ processImmediate (timers.js:647:5)
最佳答案
我可以看到生成的模板的 CacheCluster 定义中缺少 CacheSubnetGroupName。这就是缓存使用默认 VPC 的原因。
CDK 会忽略您的子网组定义，因为您分配的子网组定义不正确。
使用 Cfn 资源时，您应该使用 ref 引用代码中的其他资源，而不是像您那样直接分配资源。
您的代码只需更新以下代码行即可工作。
redis_cluster = aws_elasticache.CfnCacheCluster(
...
cache_subnet_group_name=cache_subnet_group.ref
)
关于python - AWS CDK : Error when deploying Redis ElastiCache: Subnet group belongs to a different VPC than CacheCluster，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/59643874/
