Amazon Elastic Load Balancing Construct Library
---
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.
// Example automatically generated without compilation. See https://github.com/aws/jsii/issues/826
Object lb = LoadBalancer.Builder.create(this, "LB")
.vpc(vpc)
.internetFacing(true)
.healthCheck(Map.of(
"port", 80))
.build();
lb.addTarget(myAutoScalingGroup);
lb.addListener(Map.of(
"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:
// Example automatically generated without compilation. See https://github.com/aws/jsii/issues/826
lb.addListener(Map.of(
"externalPort", 80,
"allowConnectionsFrom", asList(mySecurityGroup)));
