    11  
    12  Provides a Target Group resource for use with Application Load Balancer
    13  resources.
    14  
    15  ## Example Usage
    16  
    17  ```
    18  resource "aws_alb_target_group" "test" {
    19    name     = "tf-example-alb-tg"
    20    port     = 80
    21    protocol = "HTTP"
    22    vpc_id   = "${aws_vpc.main.id}"
    23  }
    24  
    25  resource "aws_vpc" "main" {
    26    cidr_block = "10.0.0.0/16"
    27  }
    28  ```

    30  ## Argument Reference
    31  
    32  The following arguments are supported:
    33  
    34  * `name` - (Required) The name of the target group.
    35  * `port` - (Required) The port on which targets receive traffic, unless overridden when registering a specific target.
    36  * `protocol` - (Required) The protocol to use for routing traffic to the targets.
    37  * `vpc_id` - (Required) The identifier of the VPC in which to create the target group.
    38  * `deregistration_delay` - (Optional) The amount time for Elastic Load Balancing to wait before changing the state of a deregistering target from draining to unused. The range is 0-3600 seconds. The default value is 300 seconds.
    39  * `stickiness` - (Optional) A Stickiness block. Stickiness blocks are documented below.
    40  * `health_check` - (Optional) A Health Check block. Health Check blocks are documented below.
    41  * `tags` - (Optional) A mapping of tags to assign to the resource.
    42  
    43  Stickiness Blocks (`stickiness`) support the following:
    44  
    45  * `type` - (Required) The type of sticky sessions. The only current possible value is `lb_cookie`.
    46  * `cookie_duration` - (Optional) The time period, in seconds, during which requests from a client should be routed to the same target. After this time period expires, the load balancer-generated cookie is considered stale. The range is 1 second to 1 week (604800 seconds). The default value is 1 day (86400 seconds).
    47  * `enabled` - (Optional) Boolean to enable / disable `stickiness`. Default is `true`
    48  
    49  Health Check Blocks (`health_check`) support the following:
    50  
    51  * `interval` - (Optional) The approximate amount of time, in seconds, between health checks of an individual target. Minimum value 5 seconds, Maximum value 300 seconds. Default 30 seconds.
    52  * `path` - (Optional) The destination for the health check request. Default `/`.
    53  * `port` - (Optional) The port to use to connect with the target. Valid values are either ports 1-65536, or `traffic-port`. Defaults to `traffic-port`.
    54  * `protocol` - (Optional) The protocol to use to connect with the target. Defaults to `HTTP`.
    55  * `timeout` - (Optional) The amount of time, in seconds, during which no response means a failed health check. Defaults to 5 seconds.
    56  * `healthy_threshold` - (Optional) The number of consecutive health checks successes required before considering an unhealthy target healthy. Defaults to 5.
    57  * `unhealthy_threshold` - (Optional) The number of consecutive health check failures required before considering the target unhealthy. Defaults to 2.
    58  * `matcher` (Optional) The HTTP codes to use when checking for a successful response from a target. Defaults to `200`. You can specify multiple values (for example, "200,202") or a range of values (for example, "200-299").
    59  
    60  ## Attributes Reference
    61  
    62  The following attributes are exported in addition to the arguments listed above:
    63  
    64  * `id` - The ARN of the Target Group (matches `arn`)
    65  * `arn` - The ARN of the Target Group (matches `id`)
    66  * `arn_suffix` - The ARN suffix for use with CloudWatch Metrics.

    68  ## Import
    69  
    70  Target Groups can be imported using their ARN, e.g.
    71  
    72  ```
    73  $ terraform import aws_alb_target_group.app_front_end arn:aws:elasticloadbalancing:us-west-2:187416307283:targetgroup/app-front-end/20cfe21448b66314
