ApplicationLoadBalancedFargateService with listener on one port and health check on another fails health check
Hi, I have an ApplicationLoadBalancedFargateService that exposes a service on one port, but the health check runs on another. Unfortunately, the target fails health check and terminates the task. Here's a snippet of my code
```
const hostPort = 5701;
const healthCheckPort = 8080;
taskDefinition.addContainer(stackPrefix + 'Container', {
image: ecs.ContainerImage.fromRegistry('hazelcast/hazelcast:3.12.6'),
environment : {
'JAVA_OPTS': `-Dhazelcast.local.publicAddress=localhost:${hostPort} -Dhazelcast.rest.enabled=true`,
'LOGGING_LEVEL':'DEBUG',
'PROMETHEUS_PORT': `${healthCheckPort}`},
portMappings: [{containerPort : hostPort, hostPort: hostPort},{containerPort : healthCheckPort, hostPort: healthCheckPort}],
logging: ecs.LogDriver.awsLogs({streamPrefix: stackPrefix, logRetention: logs.RetentionDays.ONE_DAY}),
});
const loadBalancedFargateService = new ecsPatterns.ApplicationLoadBalancedFargateService(this, stackPrefix + 'Service', {
cluster,
publicLoadBalancer : false,
desiredCount: 1,
listenerPort: hostPort,
taskDefinition: taskDefinition,
securityGroups : [fargateServiceSecurityGroup],
domainName : env.getPrefixedRoute53(stackName),
domainZone : env.getDomainZone(),
});
loadBalancedFargateService.targetGroup.configureHealthCheck({
path: "/metrics",
port: healthCheckPort.toString(),
timeout: cdk.Duration.seconds(15),
interval: cdk.Duration.seconds(30),
healthyThresholdCount: 2,
unhealthyThresholdCount: 5,
healthyHttpCodes: '200-299'
});
```
Any suggestions on how I can get this to work? thanks
