# Step 3: Create a VPC endpoint for Amazon Keyspaces In this step, you create a dual-stack VPC endpoint for Amazon Keyspaces using the AWS CLI. To create the VPC endpoint using the VPC console, you can follow the [ Create a VPC endpoint](https://docs.aws.amazon.com/vpc/latest/privatelink/create-interface-endpoint.html#create-interface-endpoint) instructions in the *AWS PrivateLink Guide*. When filtering for the ** Service name**, enter **Cassandra**. **To create a VPC endpoint using the AWS CLI** 1. Before you begin, verify that you can communicate with Amazon Keyspaces using its public endpoint. ``` aws keyspaces list-tables --keyspace-name 'myKeyspace' ``` The output shows a list of Amazon Keyspaces tables that are contained in the specified keyspace. If you don't have any tables, the list is empty. ``` { "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" } ] } ``` 1. Verify that Amazon Keyspaces is an available service for creating VPC endpoints in the current AWS Region. (The command is shown in bold text, followed by example output.) ``` aws ec2 describe-vpc-endpoint-services { "ServiceNames": [ "com.amazonaws.us-east-1.cassandra", "com.amazonaws.us-east-1.cassandra-fips" "api.aws.us-east-1.cassandra-streams" ] } ``` If Amazon Keyspaces is one of the available services in the output of the command, you can proceed with creating a VPC endpoint. 1. To connect to Amazon Keyspaces using IPv6 enabled dual-stack endpoints, confirm that your VPC supports IPv6 and configure subnets with IPv6 support. To add IPv6 support to an existing VPC that currently only supports IPv4, see [ IPv6 support for your VPC](https://docs.aws.amazon.com/vpc/latest/userguide/) in the *Amazon VPC User Guide;*. 1. Determine your VPC identifier. ``` aws ec2 describe-vpcs { "Vpcs": [ { "OwnerId": "111122223333", "InstanceTenancy": "default", "Ipv6CidrBlockAssociationSet": [ { "AssociationId": "vpc-cidr-assoc-0000aaa0a00a00aa0", "Ipv6CidrBlock": "2600:1f18:e19:7d00::/56", "Ipv6CidrBlockState": { "State": "associated" }, "NetworkBorderGroup": "us-east-1", "Ipv6Pool": "Amazon", "Ipv6AddressAttribute": "public", "IpSource": "amazon" } ], "CidrBlockAssociationSet": [ { "AssociationId": "vpc-cidr-assoc-00a0000a", "CidrBlock": "111.11.0.0/16", "CidrBlockState": { "State": "associated" } } ], "IsDefault": true, "BlockPublicAccessStates": { "InternetGatewayBlockMode": "off" }, "VpcId": "vpc-a1234bcd", "State": "available", "CidrBlock": "111.11.0.0/16", "DhcpOptionsId": "dopt-a00aaaaa" } ] } ``` In the example output, the VPC ID is `vpc-a1234bcd`. 1. Use a filter to gather details about the subnets of the VPC. ``` aws ec2 describe-subnets --filters "Name=vpc-id,Values=vpc-a1234bcd" { "Subnets": [ { "AvailabilityZoneId": "use1-az1", "MapCustomerOwnedIpOnLaunch": false, "OwnerId": "111122223333", "AssignIpv6AddressOnCreation": false, "Ipv6CidrBlockAssociationSet": [ { "AssociationId": "subnet-cidr-assoc-05d75732736740283", "Ipv6CidrBlock": "***********************", "Ipv6CidrBlockState": { "State": "associated" }, "Ipv6AddressAttribute": "public", "IpSource": "amazon" } ], "SubnetArn": "arn:aws:ec2:us-east-1:111122223333:subnet/subnet-70b24b16", "EnableDns64": false, "Ipv6Native": false, "PrivateDnsNameOptionsOnLaunch": { "HostnameType": "ip-name", "EnableResourceNameDnsARecord": false, "EnableResourceNameDnsAAAARecord": false }, "BlockPublicAccessStates": { "InternetGatewayBlockMode": "off" }, "SubnetId": "subnet-70b24b16", "State": "available", "VpcId": "vpc-a1234bcd", "CidrBlock": "**********/20", "AvailableIpAddressCount": 4089, "AvailabilityZone": "us-east-1a", "DefaultForAz": true, "MapPublicIpOnLaunch": true }, { "AvailabilityZoneId": "use1-az2", "MapCustomerOwnedIpOnLaunch": false, "OwnerId": "111122223333", "AssignIpv6AddressOnCreation": false, "Ipv6CidrBlockAssociationSet": [ { "AssociationId": "subnet-cidr-assoc-0ec6fb253e05b17eb", "Ipv6CidrBlock": "***********************", "Ipv6CidrBlockState": { "State": "associated" }, "Ipv6AddressAttribute": "public", "IpSource": "amazon" } ], "SubnetArn": "arn:aws:ec2:us-east-1:111122223333:subnet/subnet-c63ffbe7", "EnableDns64": false, "Ipv6Native": false, "PrivateDnsNameOptionsOnLaunch": { "HostnameType": "ip-name", "EnableResourceNameDnsARecord": false, "EnableResourceNameDnsAAAARecord": false }, "BlockPublicAccessStates": { "InternetGatewayBlockMode": "off" }, "SubnetId": "subnet-c63ffbe7", "State": "available", "VpcId": "vpc-a1234bcd", "CidrBlock": "***********/20", "AvailableIpAddressCount": 4087, "AvailabilityZone": "us-east-1b", "DefaultForAz": true, "MapPublicIpOnLaunch": true } ] } ``` In the example output, there are two available subnet IDs: `subnet-70b24b16` and `subnet-c63ffbe7`. 1. Create the VPC endpoint. For the `--vpc-id` parameter, specify the VPC ID from the previous step. For the `--subnet-ids` parameter, specify the subnet IDs from the previous step. Use the `--vpc-endpoint-type` parameter to define the endpoint as an interface. To create a dual-stack endpoint, use `--ip-address-type dualstack`.
