    volumes:
      - ./task-definition.tpl.json:/work/task-definition.tpl.json

.env file with the following variables:

# Required variables
APP_NAME=<ecs service name>
CLUSTER_NAME=<ecs cluster name>
IMAGE_NAME=<ecr image arn>
CONTAINER_PORT=80
AWS_DEFAULT_REGION=

# App-specific variables (as used on task-definition below)
DB_HOST=
DB_USER=
DB_PASSWORD=
DB_NAME=

If the service type is Fargate, and you're using the run-task.sh script, please include:

SERVICE_TYPE=FARGATE
SUBNETS=subnet1231231,subnet123123123,subnter123123123123

Default values are: null

    {
      "essential": true,
      "image": "${IMAGE_NAME}",
      "memoryReservation": 512,

      "portMappings": [
        {
          "containerPort": ${CONTAINER_PORT}
        }
      ],

        "logDriver": "awslogs",
        "options": {
          "awslogs-group": "ecs-${CLUSTER_NAME}-${APP_NAME}",
          "awslogs-region": "ap-southeast-2",
          "awslogs-stream-prefix": "web"
        }
      },
      "environment" : [
        { "name" : "DB_HOST", "value" : "${WODB_HOST}" },
        { "name" : "DB_USER", "value" : "${DB_USER}" },
        { "name" : "DB_PASSWORD", "value" : "${DB_PASSWORD}" },
        { "name" : "DB_NAME", "value" : "${DB_NAME}" }
      ]
    }
  ],
  "family": "${APP_NAME}"
}

Run the service to deploy:

docker-compose run --rm deploy

Caveats

Make sure the log group specified in the task definition exists in Cloudwatch Logs
CodeDeploy Application and Deployment Group should exist and be called $CLUSTER_NAME-$APP_NAME

This container is made to be used with our terraform modules:
