我找到了一些有关仅将 NAT 实例设置为私有(private)子网的示例。我不想让 AWS 在每个可用区中创建 NAT 网关,因为我不打算拥有多个可用区。

最佳答案

我可能误解了你的问题。我的工作按照以下方式进行(Python)。使用 ec2.Vpc.fromlookup 获取 vpc。

allocation_id = 'eipalloc-xxx1'

nat_gateway = ec2.CfnNatGateway(
self,
'My-Nat-Gateway',
allocation_id = allocation_id,
subnet_id = 'subnet-1234' # the ID of the first default subnet in the VPC, in my case it was ok not to do it for all subnets
)

ip_range_index_offset = 3

for i, az in enumerate(vpc.availability_zones):
sub_net = ec2.PrivateSubnet(
self,
id = 'private-subnet-' + str(i),
availability_zone = az,
cidr_block = '123.12.'+ str(16 * (i+ip_range_index_offset)) +'.0/20', # there is likely a better way to do this
vpc_id = vpc.vpc_id,
)

route_table_entry = ec2.CfnRoute(
self,
id = 'route-table-entry' + str(i),
route_table_id = sub_net.route_table.route_table_id,
destination_cidr_block = '0.0.0.0/0',
nat_gateway_id = nat_gateway.ref
)
