我正在使用 ECS-CLI (0.4.5) 启动 CFN 模板,现在我正在尝试将 Aurora 集群放入 CFN 模板并通过 CFN SDK 使用变更集更新堆栈。
我不明白为什么它对我的子网感到不安。子网由初始的“ecs-cli up”调用创建。它们与堆栈的其余部分位于同一个 vpc 中,在我尝试部署变更集之前它们已经存在,并且它们位于不同的可用区(us-west-2b 和 us-west-2c)。
CFN 给我的唯一信息是“某些输入子网无效”。
CFN 故障:
子网:
我可以通过管理控制台创建一个具有完全相同子网的 DBSubnetGroup,没有任何问题。
关于可能出现问题的任何想法?这是 CloudFormation 中的错误吗?让我知道是否需要更多信息来解决这个问题......老实说,我很茫然
这是我最初的模板归结为(它内置在 ecs-cli 中):
"PubSubnetAz1": {
"Type": "AWS::EC2::Subnet",
"Properties": {
"VpcId": {
"Ref": "Vpc"
},
"CidrBlock": "10.0.0.0/24",
"AvailabilityZone": "us-west-2b"
}
},
"PubSubnetAz2": {
"Type": "AWS::EC2::Subnet",
"Properties": {
"VpcId": {
"Ref": "Vpc"
},
"CidrBlock": "10.0.1.0/24",
"AvailabilityZone": "us-west-2c"
}
},
"InternetGateway": {
"Type": "AWS::EC2::InternetGateway"
},
"AttachGateway": {
"Type": "AWS::EC2::VPCGatewayAttachment",
"Properties": {
"VpcId": {
"Ref": "Vpc"
},
"InternetGatewayId": {
"Ref": "InternetGateway"
}
}
},
"RouteViaIgw": {
"Type": "AWS::EC2::RouteTable",
"Properties": {
"VpcId": {
"Ref": "Vpc"
}
}
},
"PublicRouteViaIgw": {
"DependsOn": "AttachGateway",
"Type": "AWS::EC2::Route",
"Properties": {
"RouteTableId": {
"Ref": "RouteViaIgw"
},
"DestinationCidrBlock": "0.0.0.0/0",
"GatewayId": {
"Ref": "InternetGateway"
}
}
},
"PubSubnet1RouteTableAssociation": {
"Type": "AWS::EC2::SubnetRouteTableAssociation",
"Properties": {
"SubnetId": {
"Ref": "PubSubnetAz1"
},
"RouteTableId": {
"Ref": "RouteViaIgw"
}
}
},
"PubSubnet2RouteTableAssociation": {
"Type": "AWS::EC2::SubnetRouteTableAssociation",
"Properties": {
"SubnetId": {
"Ref": "PubSubnetAz2"
},
"RouteTableId": {
"Ref": "RouteViaIgw"
}
}
},
然后当我去更新它时,我添加了这个:
"DBSubnetGroup": {
"Type": "AWS::RDS::DBSubnetGroup",
"Properties": {
"DBSubnetGroupDescription": "Aurora Subnet Group using subnets from 2 AZs",
"SubnetIds": {
"Fn::Join": [
",", [{
"Ref": "pubSubnetAz1"
},
{
"Ref": "pubSubnetAz2"
}
]
]
}]
}
}
}
变更集应该足够简单......
"Changes": [
{
"Type": "Resource",
"ResourceChange": {
"Action": "Add",
"LogicalResourceId": "DBSubnetGroup",
"ResourceType": "AWS::RDS::DBSubnetGroup",
"Scope": [],
"Details": []
}
}
]
我正在使用 AWSTemplateFormatVersion 2010-09-09 和 JavaScript aws-sdk "^2.7.21"
