# LoadBalancerInfoProperty

The `LoadBalancerInfo` property type specifies information about the load balancer or target group used for an AWS CodeDeploy deployment group.

For more information, see [Integrating CodeDeploy with Elastic Load Balancing](https://docs.aws.amazon.com/codedeploy/latest/userguide/integrations-aws-elastic-load-balancing.html) in the *AWS CodeDeploy User Guide* .

For CloudFormation to use the properties specified in `LoadBalancerInfo` , the `DeploymentStyle.DeploymentOption` property must be set to `WITH_TRAFFIC_CONTROL` . If `DeploymentStyle.DeploymentOption` is not set to `WITH_TRAFFIC_CONTROL` , CloudFormation ignores any settings specified in `LoadBalancerInfo` .

> CloudFormation supports blue/green deployments on the AWS Lambda compute platform only.

`LoadBalancerInfo` is a property of the [DeploymentGroup](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-codedeploy-deploymentgroup.html) resource.

## Example

```ts

// The values are placeholders you should change.
import { aws_codedeploy as codedeploy } from 'aws-cdk-lib';
const loadBalancerInfoProperty: codedeploy.CfnDeploymentGroup.LoadBalancerInfoProperty = {
  elbInfoList: [{
    name: 'name',
  }],
  targetGroupInfoList: [{
    name: 'name',
  }],
  targetGroupPairInfoList: [{
    prodTrafficRoute: {
      listenerArns: ['listenerArns'],
    },
    targetGroups: [{
      name: 'name',
    }],

## Properties

- `elbInfoList`: [IResolvable](/cdk/api/v2/docs/aws-cdk-lib.IResolvable.html) | [IResolvable](/cdk/api/v2/docs/aws-cdk-lib.IResolvable.html) | [CfnDeploymentGroup.ELBInfoProperty](/cdk/api/v2/docs/aws-cdk-lib.aws_codedeploy.CfnDeploymentGroup.ELBInfoProperty.html)[] — An array that contains information about the load balancers to use for load balancing in a deployment.

  If you're using Classic Load Balancers, specify those load balancers in this array.

  > You can add up to 10 load balancers to the array. > If you're using Application Load Balancers or Network Load Balancers, use the `targetGroupInfoList` array instead of this one.

- `targetGroupInfoList`: [IResolvable](/cdk/api/v2/docs/aws-cdk-lib.IResolvable.html) | [IResolvable](/cdk/api/v2/docs/aws-cdk-lib.IResolvable.html) | [CfnDeploymentGroup.TargetGroupInfoProperty](/cdk/api/v2/docs/aws-cdk-lib.aws_codedeploy.CfnDeploymentGroup.TargetGroupInfoProperty.html)[] — An array that contains information about the target groups to use for load balancing in a deployment.

  If you're using Application Load Balancers and Network Load Balancers, specify their associated target groups in this array.

  > You can add up to 10 target groups to the array. > If you're using Classic Load Balancers, use the `elbInfoList` array instead of this one.

- `targetGroupPairInfoList`: [IResolvable](/cdk/api/v2/docs/aws-cdk-lib.IResolvable.html) | [IResolvable](/cdk/api/v2/docs/aws-cdk-lib.IResolvable.html) | [CfnDeploymentGroup.TargetGroupPairInfoProperty](/cdk/api/v2/docs/aws-cdk-lib.aws_codedeploy.CfnDeploymentGroup.TargetGroupPairInfoProperty.html)[] — The target group pair information.

  This is an array of `TargeGroupPairInfo` objects with a maximum size of one.
