步骤 3：为 Amazon Keyspaces 创建 VPC 端点

在这一步中，您将使用 Amazon CLI为 Amazon Keyspaces 创建 VPC 端点。要使用 VPC 控制台创建 VPC 端点，您可以按照 Amazon PrivateLink 指南中的创建 VPC 端点进行操作。筛选服务名称时，请输入 Cassandra。

使用创建 VPC 终端节点 Amazon CLI

  1. 在开始之前，请验证您是否可以使用 Amazon Keyspaces 的公共端点与其进行通信。

    aws keyspaces list-tables --keyspace-name 'myKeyspace'

    输出显示了包含在指定键空间中的 Amazon Keyspaces 表的列表。如果您没有任何表，该列表将为空。

    {
    "tables": [
        {
            "keyspaceName": "myKeyspace",
            "tableName": "myTable1",
            "resourceArn": "arn:aws:cassandra:us-east-1:111122223333:/keyspace/catalog/table/myTable1"
        },
        {
            "keyspaceName": "myKeyspace",
            "tableName": "myTable2",
            "resourceArn": "arn:aws:cassandra:us-east-1:111122223333:/keyspace/catalog/table/myTable2"
        }
    ]
}

  2. 验证 Amazon Keyspaces 是否为在当前 Amazon 区域创建 VPC 终端节点的可用服务。（命令以粗体文本显示，后面是示例输出。）

    aws ec2 describe-vpc-endpoint-services
 
{
    "ServiceNames": [
        "com.amazonaws.us-east-1.cassandra", 
        "com.amazonaws.us-east-1.cassandra-fips"
    ]
}

    在示例输出中，Amazon Keyspaces 是可用的服务之一，因此您可以继续为其创建 VPC 端点。

  3. 确定您的 VPC 标识符。

    aws ec2 describe-vpcs
 
{
    "Vpcs": [
        {
            "VpcId": "vpc-a1234bcd", 
            "InstanceTenancy": "default", 
            "State": "available", 
            "DhcpOptionsId": "dopt-8454b7e1", 
            "CidrBlock": "111.31.0.0/16", 
            "IsDefault": true
        }
    ]
}

    在示例输出中，VPC ID 为 vpc-a1234bcd。

  4. 使用筛选条件来收集有关 VPC 子网的详细信息。

    aws ec2 describe-subnets --filters "Name=vpc-id,Values=vpc-a1234bcd"
 
{
     {
    "Subnets":[
       {
          "AvailabilityZone":"us-east-1a",
          "AvailabilityZoneId":"use2-az1",
          "AvailableIpAddressCount":4085,
          "CidrBlock":"111.31.0.0/20",
          "DefaultForAz":true,
          "MapPublicIpOnLaunch":true,
          "MapCustomerOwnedIpOnLaunch":false,
          "State":"available",
          "SubnetId":"subnet-920aacf9",
          "VpcId":"vpc-a1234bcd",
          "OwnerId":"111122223333",
          "AssignIpv6AddressOnCreation":false,
          "Ipv6CidrBlockAssociationSet":[
             
          ],
          "SubnetArn":"arn:aws:ec2:us-east-1:111122223333:subnet/subnet-920aacf9",
          "EnableDns64":false,
          "Ipv6Native":false,
          "PrivateDnsNameOptionsOnLaunch":{
             "HostnameType":"ip-name",
             "EnableResourceNameDnsARecord":false,
             "EnableResourceNameDnsAAAARecord":false
          }
       },
       {
          "AvailabilityZone":"us-east-1c",
          "AvailabilityZoneId":"use2-az3",
          "AvailableIpAddressCount":4085,
          "CidrBlock":"111.31.32.0/20",
          "DefaultForAz":true,
          "MapPublicIpOnLaunch":true,
          "MapCustomerOwnedIpOnLaunch":false,
          "State":"available",
          "SubnetId":"subnet-4c713600",
          "VpcId":"vpc-a1234bcd",
          "OwnerId":"111122223333",
          "AssignIpv6AddressOnCreation":false,
          "Ipv6CidrBlockAssociationSet":[
             
          ],
          "SubnetArn":"arn:aws:ec2:us-east-1:111122223333:subnet/subnet-4c713600",
          "EnableDns64":false,
          "Ipv6Native":false,
          "PrivateDnsNameOptionsOnLaunch":{
             "HostnameType":"ip-name",
             "EnableResourceNameDnsARecord":false,
             "EnableResourceNameDnsAAAARecord":false
          }
       },
       {
          "AvailabilityZone":"us-east-1b",
          "AvailabilityZoneId":"use2-az2",
          "AvailableIpAddressCount":4086,
          "CidrBlock":"111.31.16.0/20",
          "DefaultForAz":true,
          "MapPublicIpOnLaunch":true,
          

        }
    ]
}

    在示例输出中，有两个可用的子网 ID：subnet-920aacf9 和 subnet-4c713600。

  5. 创建 VPC 端点。对于 --vpc-id 参数，指定上一步中的 VPC ID。对于 --subnet-id 参数，指定上一步中的 子网 ID。使用 --vpc-endpoint-type 参数将端点定义为接口。有关命令的更多信息，请参阅 Amazon CLI 命令参考中的 create-vpc-endpoint。

    aws ec2 create-vpc-endpoint --vpc-endpoint-type Interface --vpc-id vpc-a1234bcd --service-name com.amazonaws.us-east-1.cassandra --subnet-id subnet-920aacf9 subnet-4c713600
