Options

--name (string)

The name of the target group.

This name must be unique per region per account, can have a maximum of 32 characters, must contain only alphanumeric characters or hyphens, and must not begin or end with a hyphen.

--protocol (string)

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.

Possible values:

  • HTTP
  • HTTPS
  • TCP
  • TLS
  • UDP
  • TCP_UDP
  • GENEVE

--protocol-version (string)

[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.

--port (integer)

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.

--vpc-id (string)

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.

--health-check-protocol (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.

Possible values:

  • HTTP
  • HTTPS
  • TCP
  • TLS
  • UDP
  • TCP_UDP
  • GENEVE

--health-check-port (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.

--health-check-enabled | --no-health-check-enabled (boolean)

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.

--health-check-path (string)

[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.

--health-check-interval-seconds (integer)

The approximate amount of time, in seconds, between health checks of an individual target. If the target group protocol is TCP, TLS, UDP, or TCP_UDP, the supported values are 10 and 30 seconds. If the target group protocol is 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.

--health-check-timeout-seconds (integer)

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.

--healthy-threshold-count (integer)

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.

--unhealthy-threshold-count (integer)

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.

--matcher (structure)

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

HttpCode -> (string)

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 and Gateway Load Balancers, this must be "200–399".

GrpcCode -> (string)

You can specify values between 0 and 99. You can specify multiple values (for example, "0,1") or a range of values (for example, "0-5"). The default value is 12.

Shorthand Syntax:

HttpCode=string,GrpcCode=string

JSON Syntax:

{
  "HttpCode": "string",
  "GrpcCode": "string"
}

--target-type (string)

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.

Possible values:

  • instance
  • ip
  • lambda

--tags (list)

The tags to assign to the target group.

(structure)

Information about a tag.

Key -> (string)

The key of the tag.

Value -> (string)

The value of the tag.

Shorthand Syntax:

Key=string,Value=string ...

JSON Syntax:

[
  {
    "Key": "string",
    "Value": "string"
  }
  ...
]

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See 'aws help' for descriptions of global parameters.

Examples

Example 1: To create a target group to route traffic to instances registered by instance ID

The following create-target-group example creates a target group for an Application Load Balancer where you register targets by instance ID (the target type is instance). This target group uses the HTTP protocol, port 80, and the default health check settings for an HTTP target group.

aws elbv2 create-target-group \
    --name my-targets \
    --protocol HTTP \
    --port 80 \
    --target-type instance \
    --vpc-id vpc-3ac0fb5f

Output:

{
    "TargetGroups": [
        {
            "TargetGroupName": "my-targets",
            "Protocol": "HTTP",
            "Port": 80,
            "VpcId": "vpc-3ac0fb5f",
            "TargetType": "instance",

            },
            "HealthCheckProtocol": "HTTP",
            "HealthCheckPort": "traffic-port",
            "HealthCheckIntervalSeconds": 30,
            "HealthCheckTimeoutSeconds": 5,
            "TargetGroupArn": "arn:aws:elasticloadbalancing:us-west-2:123456789012:targetgroup/my-targets/73e2d6bc24d8a067"
        }
    ]
}

Example 2: To create a target group to route traffic to an IP addresses

The following create-target-group example creates a target group for a Network Load Balancer where you register targets by IP address (the target type is ip). This target group uses the TCP protocol, port 80, and the default health check settings for a TCP target group.

aws elbv2 create-target-group \
    --name my-ip-targets \
    --protocol TCP \
    --port 80 \
    --target-type ip \
    --vpc-id vpc-3ac0fb5f

Output:

{
    "TargetGroups": [
        {
            "TargetGroupName": "my-ip-targets",
            "Protocol": "TCP",
            "Port": 80,
            "VpcId": "vpc-3ac0fb5f",
            "TargetType": "ip",
            "HealthCheckEnabled": true,
            "UnhealthyThresholdCount": 3,
            "HealthyThresholdCount": 3,
            "HealthCheckProtocol": "TCP",
            "HealthCheckPort": "traffic-port",
            "HealthCheckIntervalSeconds": 30,
            "HealthCheckTimeoutSeconds": 10,
            "TargetGroupArn": "arn:aws:elasticloadbalancing:us-west-2:123456789012:targetgroup/my-ip-targets/b6bba954d1361c78"
        }
    ]
}

Example 3: To create a target group to route traffic to a Lambda function

The following create-target-group example creates a target group for an Application Load Balancer where the target is a Lambda function (the target type is lambda). Health checks are disabled for this target group by default.

aws elbv2 create-target-group \
    --name my-lambda-target \
    --target-type lambda

Output:

{
    "TargetGroups": [
        {
            "TargetGroupName": "my-lambda-target",
            "TargetType": "lambda",
            "HealthCheckEnabled": false,
            "UnhealthyThresholdCount": 2,
            "HealthyThresholdCount": 5,
            "HealthCheckPath": "/",
            "Matcher": {
                "HttpCode": "200"
            },
            "HealthCheckIntervalSeconds": 35,
            "HealthCheckTimeoutSeconds": 30,
            "TargetGroupArn": "arn:aws:elasticloadbalancing:us-west-2:123456789012:targetgroup/my-lambda-target/a3003e085dbb8ddc"
