After deploying the ECS with an application load balancer,

curl

the load balancer throws this error I think my

portMappings

config is correct because I expose port 8080 in my Docerfile and I specify the

containerPort

to be 8080 in the

portMappings

field, e.g.

const service = new awsx.ecs.FargateService("my-service", {
  cluster: cluster,
  taskDefinitionArgs: {
    container: {
      image: image,
      cpu: 512,
      memory: 128,
      essential: true,
      portMappings: [
        {
          containerPort: 8080,
          hostPort: 8080,
        },
      ],
    },
  },
});

But I noticed the application load balancer does not have any inbound rules in its security group, could this be the reason why I am getting the error?
