I've single docker container and have to deploy on AWS Cloud using AWS ECR with Elastic Beanstalk. I'm using Dockerrun.aws.json file to provide the information about repository details. I have pushed my image to my docker hub and Elastic Container Registry.

Using DockerHub in ECS, It can pull the docker image from docker hub and starts the container without any issues and working the app as expected. On the other hand, the container gets stopped when the image pulled from AWS ECR Repository for the same application. The deployment gets failed for the reason: Essential container in task exited

Dockerrun.aws.json

{
    
    "containerDefinitions": [
        {
            "essential": true,
            "image": "01234567891.dkr.ecr.us-east-1.amazonaws.com/app:1",
            "memory": 512,
            "name": "web",
            "portMappings": [
                {
                    "containerPort": 5000,
                    "hostPort": 80
                }
            ]
        }
    ],
    "family": "",
    "volumes": [],
    "AWSEBDockerrunVersion": "2"
}

I logged into the instance and tried to get the logs of the containers. But, I got this error standard_init_linux.go:211: exec user process caused "exec format error"
