            'Value': 'lima',
        },
        {
            'Key': 'department',
            'Value': 'digital-media',
        },
    ],
)

print(response)

Expected Output:

{
    'ResponseMetadata': {
        '...': '...',
    },
}
can_paginate(operation_name)

Check if an operation can be paginated.

Parameters
operation_name (string) -- The operation name. This is the same name as the method name on the client. For example, if the method name is create_foo, and you'd normally invoke the operation as client.create_foo(**kwargs), if the create_foo operation can be paginated, you can use the call client.get_paginator("create_foo").
Returns
True if the operation can be paginated, False otherwise.
create_listener(**kwargs)

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 .

create_load_balancer(**kwargs)

Creates an Application Load Balancer or a Network Load Balancer.

When you create a load balancer, you can specify security groups, 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 .

create_rule(**kwargs)

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 condition for a rule is met, the specified action is taken. If no conditions are met, the action for the default rule is taken. 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 .

create_target_group(**kwargs)

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 .

  • Protocol (string) --

    [REQUIRED]

    The protocol to use for routing traffic to the targets. For Application Load Balancers, the supported protocols are HTTP and HTTPS. For Network Load Balancers, the supported protocol is TCP.

  • Port (integer) --

    [REQUIRED]

    The port on which the targets receive traffic. This port is used unless you specify a port override when registering the target.

  • VpcId (string) --

    [REQUIRED]

    The identifier of the virtual private cloud (VPC).

  • HealthCheckProtocol (string) -- The protocol the load balancer uses when performing health checks on targets. The TCP protocol is supported only if the protocol of the target group is TCP. For Application Load Balancers, the default is HTTP. For Network Load Balancers, the default is TCP.
  • HealthCheckPort (string) -- The port the load balancer uses when performing health checks on targets. The default is traffic-port , which is the port on which each target receives traffic from the load balancer.
  • HealthCheckPath (string) -- [HTTP/HTTPS health checks] The ping path that is the destination on the targets for health checks. The default is /.
  • HealthCheckIntervalSeconds (integer) -- The approximate amount of time, in seconds, between health checks of an individual target. For Application Load Balancers, the range is 5 to 300 seconds. For Network Load Balancers, the supported values are 10 or 30 seconds. The default is 30 seconds.
  • HealthCheckTimeoutSeconds (integer) -- The amount of time, in seconds, during which no response from a target means a failed health check. For Application Load Balancers, the range is 2 to 60 seconds and the default is 5 seconds. For Network Load Balancers, this is 10 seconds for TCP and HTTPS health checks and 6 seconds for HTTP health checks.
  • HealthyThresholdCount (integer) -- The number of consecutive health checks successes required before considering an unhealthy target healthy. For Application Load Balancers, the default is 5. For Network Load Balancers, the default is 3.
  • UnhealthyThresholdCount (integer) -- The number of consecutive health check failures required before considering a target unhealthy. For Application Load Balancers, the default is 2. For Network Load Balancers, this value must be the same as the healthy threshold count.
  • Matcher (dict) --

    [HTTP/HTTPS health checks] The HTTP codes to use when checking for a successful response from a target.

    • HttpCode (string) -- [REQUIRED]

      The HTTP codes.

      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 to 399.

  • TargetType (string) --

    The type of target that you must specify when registering targets with this target group. The possible values are instance (targets are specified by instance ID) or ip (targets are specified by IP address). The default is instance . Note that you can't specify targets for a target group using both instance IDs and IP addresses.

    If the target type is ip , specify IP addresses from the subnets of the virtual private cloud (VPC) for the target group, the RFC 1918 range (10.0.0.0/8, 172.16.0.0/12, and 192.168.0.0/16), and the RFC 6598 range (100.64.0.0/10). You can't specify publicly routable IP addresses.

    'ResponseMetadata': {
        '...': '...',
    },
}
delete_load_balancer(**kwargs)

Deletes the specified Application Load Balancer or Network Load Balancer and its attached listeners.

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.

            • Target.ResponseCodeMismatch - The health checks did not return an expected HTTP code.
            • Target.Timeout - The health check requests timed out.
            • Target.FailedHealthChecks - The health checks failed because the connection to the target timed out, the target response was malformed, or the target failed the health check for an unknown reason.

            • Target.NotInUse - The target group is not used by any load balancer or the target is in an Availability Zone that is not enabled for its load balancer.
            • Target.IpUnusable - The target IP address is reserved for use by a load balancer.
            • Target.InvalidState - The target is in the stopped or terminated state.

          • Description (string) --

            A description of the target health that provides additional details. If the state is healthy , a description is not provided.

Examples

This example describes the health of the targets for the specified target group. One target is healthy but the other is not specified in an action, so it can't receive traffic from the load balancer.

generate_presigned_url(ClientMethod, Params=None, ExpiresIn=3600, HttpMethod=None)

Generate a presigned url given a client, its method, and arguments

Parameters
  • ClientMethod (string) -- The client method to presign for
  • Params (dict) -- The parameters normally passed to ClientMethod.
  • ExpiresIn (int) -- The number of seconds the presigned url is valid for. By default it expires in an hour (3600 seconds)

Returns

The presigned url

get_paginator(operation_name)

Create a paginator for an operation.

Parameters
operation_name (string) -- The operation name. This is the same name as the method name on the client. For example, if the method name is create_foo, and you'd normally invoke the operation as client.create_foo(**kwargs), if the create_foo operation can be paginated, you can use the call client.get_paginator("create_foo").
Raises OperationNotPageableError
Raised if the operation is not pageable. You can use the client.can_paginate method to check if an operation is pageable.
Return type
L{botocore.paginate.Paginator}
Returns
A paginator object.
get_waiter(waiter_name)
modify_listener(**kwargs)

Modifies the specified properties of the specified listener.

Any properties that you do not specify retain their current values. However, changing the protocol from HTTPS to HTTP removes the security policy and SSL certificate properties. If you change the protocol from HTTP to HTTPS, you must add the security policy and server certificate.

  • HealthCheckPort (string) -- The port the load balancer uses when performing health checks on targets.
  • HealthCheckPath (string) -- [HTTP/HTTPS health checks] The ping path that is the destination for the health check request.
  • HealthCheckIntervalSeconds (integer) -- The approximate amount of time, in seconds, between health checks of an individual target. For Application Load Balancers, the range is 5 to 300 seconds. For Network Load Balancers, the supported values are 10 or 30 seconds.
  • HealthCheckTimeoutSeconds (integer) -- [HTTP/HTTPS health checks] The amount of time, in seconds, during which no response means a failed health check.
  • HealthyThresholdCount (integer) -- The number of consecutive health checks successes required before considering an unhealthy target healthy.
  • UnhealthyThresholdCount (integer) -- The number of consecutive health check failures required before considering the target unhealthy. For Network Load Balancers, this value must be the same as the healthy threshold count.
  • Matcher (dict) --

    [HTTP/HTTPS health checks] The HTTP codes to use when checking for a successful response from a target.

    • HttpCode (string) -- [REQUIRED]

      The HTTP codes.

      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 to 399.

register_targets(**kwargs)

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 .

      • Port (integer) --

        The port on which the target is listening.

      • AvailabilityZone (string) --

        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 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 IP address is outside the VPC for the target group, the only supported value is all .
