TargetGroup

Source: src/AWS/VpcLattice/TargetGroup.ts

An Amazon VPC Lattice target group — the collection of compute targets (IPs, EC2 instances, ALBs, or Lambda functions) that a lattice service’s listeners and rules forward traffic to.

Creating Target Groups

Lambda Target Group

const targets = yield* TargetGroup("ApiTargets", {
  type: "LAMBDA",
  targets: [{ id: fn.functionArn }],
});

IP Target Group with Health Check

const targets = yield* TargetGroup("BackendTargets", {
  type: "IP",
  port: 80,
  protocol: "HTTP",
  vpcIdentifier: vpc.vpcId,
  healthCheck: {
    enabled: true,
    path: "/health",
    healthCheckInterval: "30 seconds",
    healthCheckTimeout: "5 seconds",
  },
  targets: [{ id: "10.0.1.10", port: 80 }],
});
