Inputs

Name	Description	Type	Default	Required
name	(Required) Name of the target group. A maximum of 32 alphanumeric characters including hyphens are allowed, but the name must not begin or end with a hyphen.	string	n/a	yes
port	(Required) The number of port on which targets receive traffic, unless overridden when registering a specific target. Valid values are either ports 1-65535.	number	n/a	yes
protocol	(Required) The protocol to use for routing traffic to the targets. Valid values are TCP, TLS, UDP and TCP_UDP. Not valid to use UDP or TCP_UDP if dual-stack mode is enabled on the load balancer.	string	n/a	yes
vpc_id	(Required) The ID of the VPC which the target group belongs to.	string	n/a	yes
deregistration_delay	(Optional) The time to wait for in-flight requests to complete while deregistering a target. During this time, the state of the target is draining.	number	300	no
health_check	(Optional) Health Check configuration block. The associated load balancer periodically sends requests to the registered targets to test their status. health_check block as defined below. (Optional) protocol - Protocol to use to connect with the target. The possible values are TCP, HTTP and HTTPS. Defaults to TCP. (Optional) port - The port the load balancer uses when performing health checks on targets. The default is the port on which each target receives traffic from the load balancer. Valid values are either ports 1-65535. (Optional) port_override - Whether to override the port on which each target receives trafficfrom the load balancer to a different port. Defaults to false. (Optional) path - Use the default path of / to ping the root, or specify a custom path if preferred. Only valid if the protocol is HTTP or HTTPS. (Optional) healthy_threshold - The number of consecutive health checks successes required before considering an unhealthy target healthy. Valid value range is 2 - 10. Defaults to 3. (Optional) unhealthy_threshold - The number of consecutive health check failures required before considering a target unhealthy. Valid value range is 2 - 10. Defaults to 3. (Optional) interval - Approximate amount of time, in seconds, between health checks of an individual target. Valid value range is 5 - 300. Defaults to 10. (Optional) timeout - The amount of time, in seconds, during which no response means a failed health check. Valid value range is 2 - 120. Defaults to 6 when the protocol is HTTP, and 10 when the protocol is TCP or HTTPS.	object({ protocol = optional(string, "TCP") port = optional(number, null) port_override = optional(bool, false) path = optional(string, "/") healthy_threshold = optional(number, 3) unhealthy_threshold = optional(number, 3) interval = optional(number, 10) })	{}	no
load_balancing	(Optional) A load balancing configuration of the target group. load_balancing block as defined below. (Optional) cross_zone_strategy - Determines how the load balancer routes requests across the Availability Zones. Valid values are ENABLED, DISABLED or INHERIT. Defaults to INHERIT (Use load balancer configuration).	object({ cross_zone_strategy = optional(string, "INHERIT") })	{}	no
module_tags_enabled	(Optional) Whether to create AWS Resource Tags for the module informations.	bool	true	no
preserve_client_ip	(Optional) Whether to preserve client IP addresses and ports in the packets forwarded to targets. Client IP preservation cannot be disabled if the target group protocol is UDP and TCP_UDP. Defaults to true.	bool	true	no
proxy_protocol_v2	(Optional) Whether to enable support for proxy protocol v2 on Network Load Balancers. Before you enable proxy protocol v2, make sure that your application targets can process proxy protocol headers otherwise your application might break. Defaults to false.	bool	false	no
resource_group_description	(Optional) The description of Resource Group.	string	"Managed by Terraform."	no
resource_group_enabled	(Optional) Whether to create Resource Group to find and group AWS resources which are created by this module.	bool	true	no
resource_group_name	(Optional) The name of Resource Group. A Resource Group name can have a maximum of 127 characters, including letters, numbers, hyphens, dots, and underscores. The name cannot start with AWS or aws.	string	""	no
stickiness_enabled	(Optional) Whether to enable the type of stickiness associated with this target group. If enabled, the load balancer binds a client’s session to a specific instance within the target group. Defaults to false.	bool	false	no
tags	(Optional) A map of tags to add to all resources.	map(string)	{}	no
targets	(Optional) A set of targets to add to the target group. Each value of targets block as defined below. (Required) instance - This is the Instance ID for an instance, or the container ID for an ECS container. (Optional) port - The port on which targets receive traffic.	set(object({ instance = string port = optional(number, null) }))	[]	no
terminate_connection_on_deregistration	(Optional) Whether to terminate active connections at the end of the deregistration timeout is reached on Network Load Balancers. Enabling this setting is particularly important for UDP and TCP_UDP target groups. Defaults to false.	bool	false	no
