Name *string
// 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 , ip , or alb , health checks are always enabled and cannot be disabled.
HealthCheckEnabled *bool
// The approximate amount of time, in seconds, between health checks of an
// individual target. The range is 5-300. If the target group protocol is TCP, TLS,
// UDP, TCP_UDP, HTTP or HTTPS, 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.
HealthCheckIntervalSeconds *int32
// [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 /Amazon Web
// Services.ALB/healthcheck.
HealthCheckPath *string
// 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.
HealthCheckPort *string
// 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.
HealthCheckProtocol types.ProtocolEnum
// The amount of time, in seconds, during which no response from a target means a
// failed health check. The range is 2–120 seconds. For target groups with a
// protocol of HTTP, the default is 6 seconds. For target groups with a protocol of
// TCP, TLS or HTTPS, the default is 10 seconds. For target groups with a protocol
// of GENEVE, the default is 5 seconds. If the target type is lambda , the default
// is 30 seconds.
HealthCheckTimeoutSeconds *int32
// The number of consecutive health check successes required before considering a
// target healthy. The range is 2-10. If the target group protocol is TCP, TCP_UDP,
// UDP, TLS, HTTP or HTTPS, the default is 5. For target groups with a protocol of
// GENEVE, the default is 5. If the target type is lambda , the default is 5.
HealthyThresholdCount *int32
// The type of IP address used for this target group. The possible values are ipv4
// and ipv6 . This is an optional parameter. If not specified, the IP address type
// defaults to ipv4 .
IpAddressType types.TargetGroupIpAddressTypeEnum
// [HTTP/HTTPS health checks] The HTTP or gRPC codes to use when checking for a
// successful response from a target. For target groups with a protocol of TCP,
// TCP_UDP, UDP or TLS the range is 200-599. For target groups with a protocol of
// HTTP or HTTPS, the range is 200-499. For target groups with a protocol of
// GENEVE, the range is 200-399.
Matcher *types.Matcher
// 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.
Port *int32
// 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.
Protocol types.ProtocolEnum
// [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.
ProtocolVersion *string
// The tags to assign to the target group.
Tags []types.Tag
// The type of target that you must specify when registering targets with this
// target group. You can't specify targets for a target group using more than one
// target type.
//
// - instance - Register targets by instance ID. This is the default value.
//
// - 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.
//
// - alb - Register a single Application Load Balancer as a target.
TargetType types.TargetTypeEnum
// The number of consecutive health check failures required before considering a
// target unhealthy. The range is 2-10. If the target group protocol is TCP,
// TCP_UDP, UDP, TLS, HTTP or HTTPS, the default is 2. For target groups with a
// protocol of GENEVE, the default is 2. If the target type is lambda , the default
// is 5.
UnhealthyThresholdCount *int32
// 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.
