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 . To specify the default SSL server certificate, use ModifyListener .

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 .

This example creates an HTTPS listener for the specified load balancer that forwards requests to the specified target group. Note that you must specify an SSL certificate for an HTTPS listener. You can create and manage certificates using AWS Certificate Manager (ACM). Alternatively, you can create a certificate using SSL/TLS tools, get the certificate signed by a certificate authority (CA), and upload the certificate to AWS Identity and Access Management (IAM).

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.
For more information, see Target Groups for Your Application Load Balancers in the Application Load Balancers Guide or Target Groups for Your Network Load Balancers in the Network Load Balancers Guide .

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.

The targets. If you specified a port override when you registered a target, you must specify both the target ID and the port when you deregister it.
Information about a target.
The ID of the target. If the target type of the target group is instance , specify an instance ID. If the target type is ip , specify an IP address. If the target type is lambda , specify the ARN of the Lambda function.
The port on which the target is listening.
An Availability Zone or all . This determines whether the target receives traffic from the load balancer nodes in the specified Availability Zone or from all enabled Availability Zones for the load balancer.
This parameter is not supported if the target type of the target group is instance .
If the target type is ip and the IP address is in a subnet of the VPC for the target group, the Availability Zone is automatically detected and this parameter is optional. If the IP address is outside the VPC, this parameter is required.
With an Application Load Balancer, if the target type is ip and the IP address is outside the VPC for the target group, the only supported value is all .
If the target type is lambda , this parameter is optional and the only supported value is all .

[HTTP/HTTPS health checks] The amount of time, in seconds, during which no response means a failed health check.
If the protocol of the target group is TCP, you can't modify this setting.

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").

Registers the specified targets with the specified target group.
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 .
