Run docker image on amazon ecs

Question

I have a docker image which runs with this command

docker run -it -p 8118:8118 -p 9050:9050 -d dperson/torproxy

It requires a port as an argument.

What I tried?

I pushed this image to ECR repo, created task related to this image. After I created service with network-load-balancer. But the server is not responding when I try to GET DNS name of network-load-balancer.

I think this is because I didn't configure the port for the container. How can I do this?

Have you looked at the documentation? [see here](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/authorizing-access-to-an-instance.html) — Mike Tung, Oct 18 '18 at 13:42
The **port mappings** are configured in the Container section of the Task Definition. — Matt D, Oct 18 '18 at 14:32
@MattD So when i create a task it will call 'docker run -p ' under the hood with port i configured in **port mappings**? — Vitali Skripka, Oct 18 '18 at 14:35

Port Mappings are part of the Task Definition > Container Definitions.

This can be done through the UI Add Container or using the CLI / SDK RegisterTaskDefinition

{
   "containerDefinitions": [ 
      { 
         ...
         "portMappings": [ 
            { 
               "containerPort": number,
               "hostPort": number,
               "protocol": "string"
            }
         ],
         ...
      }
   ]      
}
