public interface SubnetSelection

Customize subnets that are selected for placement of ENIs.

Constructs that allow customization of VPC placement use parameters of this type to provide placement settings.

By default, the instances are placed in the private subnets.

Example:

 Vpc vpc;
 DatabaseCluster cluster = DatabaseCluster.Builder.create(this, "Database")
         .masterUser(Login.builder()
                 .username("myuser") // NOTE: 'admin' is reserved by DocumentDB
                 .excludeCharacters("\"@/:") // optional, defaults to the set "\"@/" and is also used for eventually created rotations
                 .secretName("/myapp/mydocdb/masteruser")
                 .build())
         .instanceType(InstanceType.of(InstanceClass.R5, InstanceSize.LARGE))
         .vpcSubnets(SubnetSelection.builder()
                 .subnetType(SubnetType.PUBLIC)
                 .build())
         .vpc(vpc)
         .build();

Method Detail

getAvailabilityZones

default java.util.List<java.lang.String> getAvailabilityZones()

Select subnets only in the given AZs.

Default: no filtering on AZs is done

getOnePerAz

default java.lang.Boolean getOnePerAz()

If true, return at most one subnet per AZ.

Default: false

getSubnetFilters

default java.util.List<SubnetFilter> getSubnetFilters()

List of provided subnet filters.

Default: - none

getSubnetGroupName

default java.lang.String getSubnetGroupName()

Select the subnet group with the given name.

Select the subnet group with the given name. This only needs to be used if you have multiple subnet groups of the same type and you need to distinguish between them. Otherwise, prefer subnetType.

This field does not select individual subnets, it selects all subnets that share the given subnet group name. This is the name supplied in subnetConfiguration.

At most one of subnetType and subnetGroupName can be supplied.

Default: - Selection by type instead of by name

getSubnetName

@Deprecated
default java.lang.String getSubnetName()

Deprecated. Use `subnetGroupName` instead

(deprecated) Alias for `subnetGroupName`.

Select the subnet group with the given name. This only needs to be used if you have multiple subnet groups of the same type and you need to distinguish between them.

getSubnets

default java.util.List<ISubnet> getSubnets()

Explicitly select individual subnets.

Use this if you don't want to automatically use all subnets in a group, but have a need to control selection down to individual subnets.

Cannot be specified together with subnetType or subnetGroupName.

Default: - Use all subnets in a selected group (all private subnets by default)

getSubnetType

default SubnetType getSubnetType()

Select all subnets of the given type.

At most one of subnetType and subnetGroupName can be supplied.

Default: SubnetType.PRIVATE_WITH_NAT (or ISOLATED or PUBLIC if there are no PRIVATE_WITH_NAT subnets)

builder

static SubnetSelection.Builder builder()

Returns:

a SubnetSelection.Builder of SubnetSelection
