如何为CDK中的两个不同端口配置ELB？

Question

我有一个弹性负载均衡器为 EC2 实例提供流量。我在端口 443 上有一个应用程序运行ning，它运行很好。

现在我想运行 EC2 实例上端口 444 上的另一个应用程序。我希望能够运行第一个应用程序通过访问端口 443 和第二个应用程序通过访问端口 444 .

不知怎么的，我无法将端口 444 添加到 CDK 中的负载平衡器。我正在做这样的事情。

 const appLoadbalancer = new elbv2.ApplicationLoadBalancer(this, `${props.type}AppLoadBalancer`, {
            vpc: vpc,
            vpcSubnets: subnets,
            internetFacing: true,
        });

        const httpsListener = appLoadbalancer.addListener(`${props.type}HTTPSListener`, {
            port: 443,
            open: true,
            certificates: [props.certificate]
        });

        httpsListener.addTargets(`${props.type}HTTPSTarget`, {
            port: 443,
            targets: [autoscalingGroup],
            healthCheck: {
                enabled: true,
                healthyHttpCodes: "200,302"
            }
        });

        const httpsListener2 = appLoadbalancer.addListener(`${props.type}HTTPSListener2`, {
            port: 444,
            protocol: elbv2.ApplicationProtocol.HTTPS,
            open: true,
            certificates: [props.certificate]
        });

        httpsListener2.addTargets(`${props.type}HTTPSTarget2`, {
            port: 444,
            protocol: elbv2.ApplicationProtocol.HTTPS,
            targets: [autoscalingGroup],
            healthCheck: {
                enabled: true,
                healthyHttpCodes: "200,302"
            }
        });

如果仅针对端口 443 进行设置，则一切正常。但是当我尝试上述操作时，我得到类似的信息：

Error: Cannot add AutoScalingGroup to 2nd Target Group

我不知道这是什么意思以及如何在 cdk 中修复它...

我最终得到了这样的解决方案：

 const appLoadbalancer = new elbv2.ApplicationLoadBalancer(this, `${props.type}AppLoadBalancer`, {
            vpc: vpc,
            vpcSubnets: subnet,
            internetFacing: true,
        });

        const tg1 = new elbv2.ApplicationTargetGroup(this, "tg1", {
            vpc: vpc,
            protocol: elbv2.ApplicationProtocol.HTTPS})
        const tg2 = new elbv2.ApplicationTargetGroup(this, "tg2", {vpc: vpc,
        protocol: elbv2.ApplicationProtocol.HTTPS, port: 444})

        const httpsListener = appLoadbalancer.addListener(`${props.type}HTTPSListener`, {
            port: 443,
            protocol: elbv2.ApplicationProtocol.HTTPS,
            open: true,
            certificates: [props.certificate]
        });
        httpsListener.addTargetGroups("RestTarget", {
            targetGroups: [tg1]
        });

        const httpsListener2 = appLoadbalancer.addListener(`${props.type}HTTPSListener2`, {
            port: 444,
            protocol: elbv2.ApplicationProtocol.HTTPS,
            open: true,
            certificates: [props.certificate]
        });
        httpsListener2.addTargetGroups("RestTarget", {
            targetGroups: [tg2]
        });

        const ServiceAsg = autoscalingGroup.node.defaultChild as autoscaling.CfnAutoScalingGroup
        ServiceAsg.targetGroupArns = [tg1.targetGroupArn, tg2.targetGroupArn]
