Mapping Load Balancer Ports in the ECS Service

Question

please understand that I am not good at English.

Suppose the ECR has a repository called `AAA` and uses EXPOSE port `8080`.

Create an ECS cluster and configure containers when defining tasks.
Add port mapping information from the container, enter `8080`.
Enter container port mapping information `8080`.

You are about to create a cluster service. If you add a task that you just created here and set the load balancer type to Application, it will automatically
write `AAA 8080:8080` in the select box of the container selection to load balance.
But I want the host mapping to be `443` ports.

**Is there any way I can set it to `8080:443`?**

Accepted Answer

By "8080:443", I'm assuming you want the LB to listen on port 433 and forward traffic to containers running on 8080. In which case you need to do the following:
1) Create and configure a target group that is configured for port 8080.
2) Create and configure your load balancer to listen on port 443 (including specifying the SSL cert to use) and forward traffic to target group created in step1
3) When configuring the ECS service and specifically "Container to load balance" step, Select Add to Load balancer.

Select production listener port as 443:HTTPS and for target group name you can select the TG you created.
