A low-level client representing Elastic Load Balancing (Elastic Load Balancing v2):
import boto3
client = boto3.client('elbv2')
These are the available methods:
Adds the specified certificate to the specified secure listener.
If the certificate was already added, the call is successful but the certificate is not added again.
To list the certificates for your listener, use DescribeListenerCertificates . To remove certificates from your listener, use RemoveListenerCertificates .

Adds the specified tags to the specified Elastic Load Balancing resource. You can tag your Application Load Balancers, Network Load Balancers, and your target groups.
Each tag consists of a key and an optional value. If a resource already has a tag with the same key, AddTags updates its value.
To list the current tags for your resources, use DescribeTags . To remove tags from your resources, use RemoveTags .

Check if an operation can be paginated.
Creates a listener for the specified Application Load Balancer or Network Load Balancer.
To update a listener, use ModifyListener . When you are finished with a listener, you can delete it using DeleteListener . If you are finished with both the listener and the load balancer, you can delete them both using DeleteLoadBalancer .
This operation is idempotent, which means that it completes at most one time. If you attempt to create multiple listeners with the same settings, each call succeeds.
For more information, see Listeners for Your Application Load Balancers in the Application Load Balancers Guide and Listeners for Your Network Load Balancers in the Network Load Balancers Guide .

Creates an Application Load Balancer or a Network Load Balancer.
When you create a load balancer, you can specify security groups, public subnets, IP address type, and tags. Otherwise, you could do so later using SetSecurityGroups , SetSubnets , SetIpAddressType , and AddTags .
To create listeners for your load balancer, use CreateListener . To describe your current load balancers, see DescribeLoadBalancers . When you are finished with a load balancer, you can delete it using DeleteLoadBalancer .
For limit information, see Limits for Your Application Load Balancer in the Application Load Balancers Guide and Limits for Your Network Load Balancer in the Network Load Balancers Guide .
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.
For more information, see Application Load Balancers in the Application Load Balancers Guide and Network Load Balancers in the Network Load Balancers Guide .

Creates a rule for the specified listener. The listener must be associated with an Application Load Balancer.
Rules are evaluated in priority order, from the lowest value to the highest value. When the conditions for a rule are met, its actions are performed. If the conditions for no rules are met, the actions for the default rule are performed. For more information, see Listener Rules in the Application Load Balancers Guide .
To view your current rules, use DescribeRules . To update a rule, use ModifyRule . To set the priorities of your rules, use SetRulePriorities . To delete a rule, use DeleteRule .

Creates a target group.
To register targets with the target group, use RegisterTargets . To update the health check settings for the target group, use ModifyTargetGroup . To monitor the health of targets in the target group, use DescribeTargetHealth .
To route traffic to the targets in a target group, specify the target group in an action using CreateListener or CreateRule .
To delete a target group, use DeleteTargetGroup .
This operation is idempotent, which means that it completes at most one time. If you attempt to create multiple target groups with the same settings, each call succeeds.

You can't delete a load balancer if deletion protection is enabled. If the load balancer does not exist or has already been deleted, the call succeeds.
Deleting a load balancer does not affect its registered targets. For example, your EC2 instances continue to run and are still registered to their target groups. If you no longer need these EC2 instances, you can stop or terminate them.

Registers the specified targets with the specified target group.
You can register targets by instance ID or by IP address. If the target is an EC2 instance, it must be in the running state when you register it.
By default, the load balancer routes requests to registered targets using the protocol and port for the target group. Alternatively, you can override the port for a target when you register it. You can register each EC2 instance or IP address with the same target group multiple times using different ports.
With a Network Load Balancer, you cannot register instances by instance ID if they have the following instance types: C1, CC1, CC2, CG1, CG2, CR1, CS1, G1, G2, HI1, HS1, M1, M2, M3, and T1. You can register instances of these types by IP address.
To remove a target from a target group, use DeregisterTargets .

Response Structure
(dict) --
LoadBalancers (list) --
Information about the load balancers.
(dict) --
Information about a load balancer.
LoadBalancerArn (string) --
The Amazon Resource Name (ARN) of the load balancer.
DNSName (string) --
The public DNS name of the load balancer.

The ID of the Amazon Route 53 hosted zone associated with the load balancer.
CreatedTime (datetime) --
The date and time the load balancer was created.
LoadBalancerName (string) --
The name of the load balancer.
Scheme (string) --
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 only route requests from clients with access to the VPC for the load balancer.
VpcId (string) --
The ID of the VPC for the load balancer.
State (dict) --
The state of the load balancer.
Code (string) --
The state code. The initial state of the load balancer is provisioning . After the load balancer is fully set up and ready to route traffic, its state is active . If the load balancer could not be set up, its state is failed .
Reason (string) --
A description of the state.
Type (string) --
The type of load balancer.
AvailabilityZones (list) --
The Availability Zones for the load balancer.
(dict) --
Information about an Availability Zone.
ZoneName (string) --
The name of the Availability Zone.
SubnetId (string) --
The ID of the subnet.
LoadBalancerAddresses (list) --
[Network Load Balancers] The static IP address.
(dict) --
Information about a static IP address for a load balancer.
IpAddress (string) --
The static IP address.
AllocationId (string) --
[Network Load Balancers] The allocation ID of the Elastic IP address.
SecurityGroups (list) --
The IDs of the security groups for the load balancer.
IpAddressType (string) --
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).
NextToken (string) --
A token to resume pagination.
paginator = client.get_paginator('describe_target_groups')
Creates an iterator that will paginate through responses from ElasticLoadBalancingv2.Client.describe_target_groups().

}
)
The Amazon Resource Names (ARN) of the target groups.
The names of the target groups.
A dictionary that provides parameters to control pagination.
The total number of items to return. If the total number of items available is more than the value specified in max-items then a NextToken will be provided in the output that you can use to resume pagination.
The size of each page.
A token to specify where to start paginating. This is the NextToken from a previous response.

For Application Load Balancers, you can specify values between 200 and 499, and the default value is 200. You can specify multiple values (for example, "200,202") or a range of values (for example, "200-299").
For Network Load Balancers, this is 200–399.
