ECS Fargate with load balancer

Question

I'm trying to make to work Load balancer with ECS.

The only way I could figure out how to connect ECS task to load balancer is to create a Target group for private IP of that task (seems that Fargate services don't have EC2 instances). It works alright until I redeploy container and task changes its IP.

Is there a way to permanently connect a task to load balancer even if the IP gets changed due new deployment?

You should connect the ECS service with the Load Balancer. The ECS service will then register/deregister the ECS task(s) with the load balancer.

Please read the documentation here.

You can try to use AWS CDK to deploy your Fargate stack. There you can configure it simply, here is one example of it: Visit here to view how to do it in a simple manner with CDK
