Amazon VPC Lattice

{'config': {'lambdaEventStructureVersion': 'V1 | V2'}}

Creates a target group. A target group is a collection of targets, or compute resources, that run your application or service. A target group can only be used by a single service.

For more information, see Target groups in the Amazon VPC Lattice User Guide .

type clientToken

string

param clientToken

A unique, case-sensitive identifier that you provide to ensure the idempotency of the request. If you retry a request that completed successfully using the same client token and parameters, the retry succeeds without performing any actions. If the parameters aren't identical, the retry fails.

This field is autopopulated if not provided.

type config

dict

param config

The target group configuration. If type is set to LAMBDA , this parameter doesn't apply.

  The health check configuration.

  • enabled (boolean) --

    Indicates whether health checking is enabled.

The tags for the target group.

• (string) --

  The key of the tag.

  Constraints: Tag keys are case-sensitive and accept a maximum of 128 Unicode characters. Valid characters are Unicode letters, digits, white space, and any of the following symbols: _ . : / = + - @ May not begin with aws: .
