Method Detail

getCidrBlock

@Stability(value=Stable)
 @NotNull
String getCidrBlock()

The primary IPv4 CIDR block for the VPC.

getEnableDnsHostnames

@Stability(value=Stable)
 @Nullable
default Object getEnableDnsHostnames()

Indicates whether the instances launched in the VPC get DNS hostnames.

If enabled, instances in the VPC get DNS hostnames; otherwise, they do not. Disabled by default for nondefault VPCs. For more information, see DNS Support in Your VPC .

You can only enable DNS hostnames if you've enabled DNS support.

getEnableDnsSupport

@Stability(value=Stable)
 @Nullable
default Object getEnableDnsSupport()

Indicates whether the DNS resolution is supported for the VPC.

If enabled, queries to the Amazon provided DNS server at the 169.254.169.253 IP address, or the reserved IP address at the base of the VPC network range "plus two" succeed. If disabled, the Amazon provided DNS service in the VPC that resolves public DNS hostnames to IP addresses is not enabled. Enabled by default. For more information, see DNS Support in Your VPC .

getInstanceTenancy

@Stability(value=Stable)
 @Nullable
default String getInstanceTenancy()

The allowed tenancy of instances launched into the VPC.

• "default" : An instance launched into the VPC runs on shared hardware by default, unless you explicitly specify a different tenancy during instance launch.
• "dedicated" : An instance launched into the VPC is a Dedicated Instance by default, unless you explicitly specify a tenancy of host during instance launch. You cannot specify a tenancy of default during instance launch.

Updating InstanceTenancy requires no replacement only if you are updating its value from "dedicated" to "default" . Updating InstanceTenancy from "default" to "dedicated" requires replacement.

getTags

@Stability(value=Stable)
 @Nullable
default List<CfnTag> getTags()

The tags for the VPC.

builder

@Stability(value=Stable)
static CfnVPCProps.Builder builder()

Returns:

a CfnVPCProps.Builder of CfnVPCProps
