{'LoadBalancers': {'EnforceSecurityGroupInboundRulesOnPrivateLinkTraffic': 'string'}}

Creates an Application Load Balancer, Network Load Balancer, or Gateway Load Balancer.

For more information, see the following:

This operation is idempotent, which means that it completes at most one time. If you attempt to create multiple load balancers with the same settings, each call succeeds.

type Name:

string

param Name:

[REQUIRED]

The name of the load balancer.

This name must be unique per region per account, can have a maximum of 32 characters, must contain only alphanumeric characters or hyphens, must not begin or end with a hyphen, and must not begin with "internal-".

type Subnets:

list

param Subnets:

The IDs of the public subnets. You can specify only one subnet per Availability Zone. You must specify either subnets or subnet mappings, but not both. To specify an Elastic IP address, specify subnet mappings instead of subnets.

[Application Load Balancers] You must specify subnets from at least two Availability Zones.

[Application Load Balancers on Outposts] You must specify one Outpost subnet.

[Application Load Balancers on Local Zones] You can specify subnets from one or more Local Zones.

[Network Load Balancers] You can specify subnets from one or more Availability Zones.

[Gateway Load Balancers] You can specify subnets from one or more Availability Zones.

(string) --

type SubnetMappings:

list

param SubnetMappings:

The IDs of the public subnets. You can specify only one subnet per Availability Zone. You must specify either subnets or subnet mappings, but not both.

[Application Load Balancers] You must specify subnets from at least two Availability Zones. You cannot specify Elastic IP addresses for your subnets.

[Application Load Balancers on Outposts] You must specify one Outpost subnet.

[Application Load Balancers on Local Zones] You can specify subnets from one or more Local Zones.

[Network Load Balancers] You can specify subnets from one or more Availability Zones. You can specify one Elastic IP address per subnet if you need static IP addresses for your internet-facing load balancer. For internal load balancers, you can specify one private IP address per subnet from the IPv4 range of the subnet. For internet-facing load balancer, you can specify one IPv6 address per subnet.

[Gateway Load Balancers] You can specify subnets from one or more Availability Zones. You cannot specify Elastic IP addresses for your subnets.

(dict) --

Information about a subnet mapping.
- SubnetId (string) --
  
  The ID of the subnet.
- AllocationId (string) --
  
  [Network Load Balancers] The allocation ID of the Elastic IP address for an internet-facing load balancer.
- PrivateIPv4Address (string) --
  
  [Network Load Balancers] The private IPv4 address for an internal load balancer.
- IPv6Address (string) --
  
  [Network Load Balancers] The IPv6 address.

type SecurityGroups:

list

param SecurityGroups:

[Application Load Balancers and Network Load Balancers] The IDs of the security groups for the load balancer.

(string) --

type Scheme:

string

param Scheme:

The nodes of an Internet-facing load balancer have public IP addresses. The DNS name of an Internet-facing load balancer is publicly resolvable to the public IP addresses of the nodes. Therefore, Internet-facing load balancers can route requests from clients over the internet.

The nodes of an internal load balancer have only private IP addresses. The DNS name of an internal load balancer is publicly resolvable to the private IP addresses of the nodes. Therefore, internal load balancers can route requests only from clients with access to the VPC for the load balancer.

The default is an Internet-facing load balancer.

You cannot specify a scheme for a Gateway Load Balancer.

type Tags:

list

param Tags:

The tags to assign to the load balancer.

(dict) --

Information about a tag.
- Key (string) -- [REQUIRED]
  
  The key of the tag.
- Value (string) --
  
  The value of the tag.

type Type:

string

param Type:

The type of load balancer. The default is application.

type IpAddressType:

string

param IpAddressType:

The type of IP addresses used by the subnets for your load balancer. The possible values are ipv4 (for IPv4 addresses) and dualstack (for IPv4 and IPv6 addresses).

type CustomerOwnedIpv4Pool:

string

param CustomerOwnedIpv4Pool:

[Application Load Balancers on Outposts] The ID of the customer-owned address pool (CoIP pool).

rtype:

dict

returns:

Associates the specified security groups with the specified Application Load Balancer or Network Load Balancer. The specified security groups override the previously associated security groups.

You can't perform this operation on a Network Load Balancer unless you specified a security group for the load balancer when you created it.

You can't associate a security group with a Gateway Load Balancer.
