Elastic Load Balancing

{'Protocol': {'GENEVE'}}

{'Listeners': {'Protocol': {'GENEVE'}}}

Creates a listener for the specified Application Load Balancer, Network Load Balancer. or Gateway Load Balancer.

For more information, see the following:

• Listeners for your Application Load Balancers

• Listeners for your Network Load Balancers

• Listeners for your Gateway Load Balancers

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.

type Protocol:

string

param Protocol:

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 protocols are TCP, TLS, UDP, or TCP_UDP. For Gateway Load Balancers, the supported protocol is GENEVE. A TCP_UDP listener must be associated with a TCP_UDP target group. If the target is a Lambda function, this parameter does not apply.

type ProtocolVersion:

string

param ProtocolVersion:

[HTTP/HTTPS protocol] The protocol version. Specify GRPC to send requests to targets using gRPC. Specify HTTP2 to send requests to targets using HTTP/2. The default is HTTP1, which sends requests to targets using HTTP/1.1.

type Port:

integer

param Port:

The port on which the targets receive traffic. This port is used unless you specify a port override when registering the target. If the target is a Lambda function, this parameter does not apply. If the protocol is GENEVE, the supported port is 6081.

type VpcId:

param VpcId:

The identifier of the virtual private cloud (VPC). If the target is a Lambda function, this parameter does not apply. Otherwise, this parameter is required.

type HealthCheckProtocol:

param HealthCheckProtocol:

The protocol the load balancer uses when performing health checks on targets. For Application Load Balancers, the default is HTTP. For Network Load Balancers and Gateway Load Balancers, the default is TCP. The TCP protocol is not supported for health checks if the protocol of the target group is HTTP or HTTPS. The GENEVE, TLS, UDP, and TCP_UDP protocols are not supported for health checks.

type HealthCheckPort:

string

param HealthCheckPort:

The port the load balancer uses when performing health checks on targets. If the protocol is HTTP, HTTPS, TCP, TLS, UDP, or TCP_UDP, the default is traffic-port, which is the port on which each target receives traffic from the load balancer. If the protocol is GENEVE, the default is port 80.

type HealthCheckEnabled:

boolean

param HealthCheckEnabled:

Indicates whether health checks are enabled. If the target type is lambda, health checks are disabled by default but can be enabled. If the target type is instance or ip, health checks are always enabled and cannot be disabled.

[HTTP/HTTPS health checks] The destination for health checks on the targets.

[HTTP1 or HTTP2 protocol version] The ping path. The default is /.

[GRPC protocol version] The path of a custom health check method with the format /package.service/method. The default is /AWS.ALB/healthcheck.

type HealthCheckIntervalSeconds:

param HealthCheckIntervalSeconds:

The approximate amount of time, in seconds, between health checks of an individual target. For TCP health checks, the supported values are 10 and 30 seconds. If the target type is instance or ip, the default is 30 seconds. If the target group protocol is GENEVE, the default is 10 seconds. If the target type is lambda, the default is 35 seconds.

type HealthCheckTimeoutSeconds:

integer

param HealthCheckTimeoutSeconds:

The amount of time, in seconds, during which no response from a target means a failed health check. For target groups with a protocol of HTTP, HTTPS, or GENEVE, the default is 5 seconds. For target groups with a protocol of TCP or TLS, this value must be 6 seconds for HTTP health checks and 10 seconds for TCP and HTTPS health checks. If the target type is lambda, the default is 30 seconds.

type HealthyThresholdCount:

integer

param HealthyThresholdCount:

The number of consecutive health checks successes required before considering an unhealthy target healthy. For target groups with a protocol of HTTP or HTTPS, the default is 5. For target groups with a protocol of TCP, TLS, or GENEVE, the default is 3. If the target type is lambda, the default is 5.

type UnhealthyThresholdCount:

integer

param UnhealthyThresholdCount:

The number of consecutive health check failures required before considering a target unhealthy. If the target group protocol is HTTP or HTTPS, the default is 2. If the target group protocol is TCP or TLS, this value must be the same as the healthy threshold count. If the target group protocol is GENEVE, the default is 3. If the target type is lambda, the default is 2.

• ip - Register targets by IP address. You can 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.

• lambda - Register a single Lambda function as a target.

        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.

            • (dict) --

              Information about a static IP address for a load balancer.
