When you use the console to create a DB cluster, Amazon RDS automatically creates the writer DB instance for your DB cluster. However, when you use the AWS CLI to create a DB cluster, you must explicitly create the writer DB instance for your DB cluster using the ``create-db-instance`` AWS CLI command. :: aws rds create-db-instance \ --db-instance-identifier my-sv2-instance \ --db-cluster-identifier my-sv2-cluster \ --engine aurora-postgresql \ --db-instance-class db.serverless Output:: { "DBInstance": { "DBInstanceIdentifier": "my-sv2-instance", "DBInstanceClass": "db.serverless", "Engine": "aurora-postgresql", "DBInstanceStatus": "creating", "MasterUsername": "myuser", "AllocatedStorage": 1, "PreferredBackupWindow": "06:05-06:35", "BackupRetentionPeriod": 1, "DBSecurityGroups": [], "VpcSecurityGroups": [ { "VpcSecurityGroupId": "sg-########", "Status": "active" } ], "DBParameterGroups": [ { "DBParameterGroupName": "default.aurora-postgresql15", "ParameterApplyStatus": "in-sync" } ], "DBSubnetGroup": { "DBSubnetGroupName": "default", "DBSubnetGroupDescription": "default", "VpcId": "vpc-########", "SubnetGroupStatus": "Complete", "Subnets": [ { "SubnetIdentifier": "subnet-########", "SubnetAvailabilityZone": { "Name": "us-east-2c" }, "SubnetOutpost": {}, "SubnetStatus": "Active" }, { "SubnetIdentifier": "subnet-########", "SubnetAvailabilityZone": { "Name": "us-east-2a" }, "SubnetOutpost": {}, "SubnetStatus": "Active" }, { "SubnetIdentifier": "subnet-########", "SubnetAvailabilityZone": { "Name": "us-east-2b" }, "SubnetOutpost": {}, "SubnetStatus": "Active" } ] }, "PreferredMaintenanceWindow": "fri:09:01-fri:09:31", "PendingModifiedValues": { "PendingCloudwatchLogsExports": { "LogTypesToEnable": [ "postgresql" ] } }, "MultiAZ": false, "EngineVersion": "15.2-limitless", "AutoMinorVersionUpgrade": true, "ReadReplicaDBInstanceIdentifiers": [], "LicenseModel": "postgresql-license", "OptionGroupMemberships": [ { "OptionGroupName": "default:aurora-postgresql-15", "Status": "in-sync" } ], "PubliclyAccessible": false, "StorageType": "aurora-iopt1", "DbInstancePort": 0, "DBClusterIdentifier": "my-sv2-cluster", "StorageEncrypted": false, "DbiResourceId": "db-BIQTE3B3K3RM7M74SK5EXAMPLE", "CACertificateIdentifier": "rds-ca-rsa2048-g1", "DomainMemberships": [], "CopyTagsToSnapshot": false, "MonitoringInterval": 0, "PromotionTier": 1, "DBInstanceArn": "arn:aws:rds:us-east-2:123456789012:db:my-sv2-instance", "IAMDatabaseAuthenticationEnabled": false, "PerformanceInsightsEnabled": false, "DeletionProtection": false, "AssociatedRoles": [], "TagList": [], "CustomerOwnedIpEnabled": false, "BackupTarget": "region", "NetworkType": "IPV4", "StorageThroughput": 0, "CertificateDetails": { "CAIdentifier": "rds-ca-rsa2048-g1" }, "DedicatedLogVolume": false } } **Example 3: To create the DB shard group** The following ``create-db-shard-group`` example creates a DB shard group in your Aurora PostgreSQL primary DB cluster. :: aws rds create-db-shard-group \ --db-shard-group-identifier my-db-shard-group \ --db-cluster-identifier my-sv2-cluster \ --max-acu 768 Output:: { "DBShardGroupResourceId": "shardgroup-a6e3a0226aa243e2ac6c7a1234567890", "DBShardGroupIdentifier": "my-db-shard-group", "DBClusterIdentifier": "my-sv2-cluster", "MaxACU": 768.0, "ComputeRedundancy": 0, "Status": "creating", "PubliclyAccessible": false, "Endpoint": "my-sv2-cluster.limitless-cekycexample.us-east-2.rds.amazonaws.com" } For more information, see `Using Aurora Serverless v2 <https://docs.aws.amazon.com/AmazonRDS/latest/AuroraUserGuide/aurora-serverless-v2.html>`__ in the *Amazon Aurora User Guide*.
