DBSubnetGroup

Source: src/AWS/RDS/DBSubnetGroup.ts

An RDS DB subnet group for Aurora clusters, instances, and proxies.

RDS requires a subnet group spanning at least two Availability Zones before a cluster or instance can be placed in a VPC. Changing the name replaces the group; the subnet list updates in place.

Creating a Subnet Group

Subnet Group Across Two AZs

const subnetGroup = yield* DBSubnetGroup("SubnetGroup", {
  subnetIds: [privateSubnetA.subnetId, privateSubnetB.subnetId],
});

Place an Aurora Cluster in the Group

const cluster = yield* DBCluster("Cluster", {
  engine: "aurora-postgresql",
  dbSubnetGroupName: subnetGroup.dbSubnetGroupName,
  vpcSecurityGroupIds: [dbSecurityGroup.groupId],
});
