我有一个奇怪的问题,CloudFormation似乎是一个bug,或者更可能 - 我错过了一些非常基本的东西。
我有以下模板(一个片段)定义了两个子网和一个子网组,如下所示:
...
"redissubnet1": {
"Type": "AWS::EC2::Subnet",
"Properties": {
"CidrBlock": "10.0.8.0/24",
"AvailabilityZone": "us-east-1c",
"VpcId": {
"Ref": "myVPC"
},
"Tags": [
{
"Key": "Name",
"Value": "redissubnet1"
}
]
}
},
"redissubnet2": {
"Type": "AWS::EC2::Subnet",
"Properties": {
"CidrBlock": "10.0.9.0/24",
"AvailabilityZone": "us-east-1c",
"VpcId": {
"Ref": "myVPC"
},
"Tags": [
{
"Key": "Name",
"Value": "redissubnet2"
}
]
}
},
"SubnetGroupName": {
"Type": "AWS::ElastiCache::SubnetGroup",
"Properties": {
"Description": "Subnet group for main application redis elastic cache",
"SubnetIds": [
{
"Ref": "redissubnet1"
},
{
"Ref": "redissubnet2"
}
]
}
}
...
创建了所有资源,但SubnetGroup名称 - " SubnetGroupName" - 没有荣幸。 AWS以[a-z] - [a-z] - [a-z0-9]
格式自动分配名称有没有人遇到过这个?
我实际上要做的是在创建ElastiCache :: Cluster时按名称引用此子网组 - 但是由于资源名称不受尊重,我无法这样做。
有人有什么想法吗?感谢所有的帮助:)

答案是引用弹性缓存资源中的子网组名称,如下所示:
{
"subnet1": {
"Type": "AWS::EC2::Subnet",
"Properties": {
"CidrBlock": "10.0.8.0/24",
"AvailabilityZone": "us-east-1c",
"VpcId": {
"Ref": "myVPC"
},
"Tags": [{
"Key": "Name",
"Value": "subnet1"
}]
}
},
"subnet2": {
"Type": "AWS::EC2::Subnet",
"Properties": {
"CidrBlock": "10.0.9.0/24",
"AvailabilityZone": "us-east-1c",
"VpcId": {
"Ref": "myVPC"
},
"Tags": [{
"Key": "Name",
"Value": "subnet2"
}]
}
},
"redis1": {
"Type": "AWS::ElastiCache::SubnetGroup",
"Properties": {
"Description": "Subnet group for main application redis elastic cache",
"SubnetIds": [{
"Ref": "subnet1"
}, {
"Ref": "subnet2"
}]
}
},
"mainredis": {
"Type": "AWS::ElastiCache::CacheCluster",
"Properties": {
"AutoMinorVersionUpgrade": "true",
"CacheNodeType": "cache.t2.small",
"CacheSubnetGroupName": {
"Ref": "redis1"
},
"ClusterName": "mainredis",
"Engine": "redis",
"NumCacheNodes": "1",
"Port": "6379",
"Tags": [{
"Key": "Name",
"Value": "mainredis"
}, {
"Key": "Function",
"Value": "Main redis store"
}],
"VpcSecurityGroupIds": [
"redissecuritygroup"
]
}
}
}
