Amazon Elastic Load Balancing Construct Library

cfn-resources: Stable

cdk-constructs: Stable

The @aws-cdk/aws-elasticloadbalancing package provides constructs for configuring classic load balancers.

Configuring a Load Balancer

Load balancers send traffic to one or more AutoScalingGroups. Create a load balancer, set up listeners and a health check, and supply the fleet(s) you want to load balance to in the targets property.

const lb = new elb.LoadBalancer(this, 'LB', {
    internetFacing: true,
    healthCheck: {
        port: 80

    externalPort: 80,

The load balancer allows all connections by default. If you want to change that, pass the allowConnectionsFrom property while setting up the listener:

    externalPort: 80,
    allowConnectionsFrom: [mySecurityGroup]

If you find any bugs or have a feature request, please open an issue on github!
