Django and Nginx Docker Containers with AWS ECS Error - django

Question

I am currently building a project using Terraform and AWS ECS with two containers: Django App and Nginx (to host the static files). Currently it works great; however, I am receiving an error in the logs of Nginx (using CloudWatch Logs) saying,
CommandError: You must set settings.ALLOWED_HOSTS if DEBUG is False.
I know this has to do with Django's ALLOWED_HOSTS since my DEBUG is set to False in the settings.py file, but I feel everything should be working as it should. Here is what my settings.py has for ALLOWED_HOSTS:
ALLOWED_HOSTS = os.getenv('ALLOWED_HOSTS', '').split()
From here, I have my task definition file named container-def.json to do the job in AWS ECS:
[
{
"name": "django-app",
"image": "${django_docker_image}",
"cpu": 10,
"memory": 256,
"memoryReservation": 128,
"links": [],
"essential": true,
"portMappings": [
{
"hostPort": 0,
"containerPort": 8000,
"protocol": "tcp"
}
],
"command": ["gunicorn", "-w", "3", "-b", ":8000", "project.wsgi:application"],
"environment": [
{
"name": "RDS_DB_NAME",
"value": "${rds_db_name}"
},
{
"name": "RDS_USERNAME",
"value": "${rds_username}"
},
{
"name": "RDS_PASSWORD",
"value": "${rds_password}"
},
{
"name": "RDS_PORT",
"value": "5432"
},
{
"name": "ALLOWED_HOSTS",
"value": "${allowed_hosts}"
}
],
"mountPoints": [
{
"containerPath": "/usr/src/app/staticfiles",
"sourceVolume": "static_volume"
}
],
"logConfiguration": {
"logDriver": "awslogs",
"options": {
"awslogs-group" : "/ecs/frontend-container",
"awslogs-region": "us-east-1"
}
}
},
{
"name": "nginx",
"image": "${ngnix_docker_image}",
"essential": true,
"cpu": 10,
"memory": 128,
"links": ["django-app"],
"portMappings": [
{
"hostPort": 0,
"containerPort": 80,
"protocol": "tcp"
}
],
"mountPoints": [
{
"containerPath": "/usr/src/app/staticfiles",
"sourceVolume": "static_volume"
}
],
"logConfiguration": {
"logDriver": "awslogs",
"options": {
"awslogs-group": "/ecs/nginx",
"awslogs-region": "us-east-1"
}
}
}
]
My var.tf file where it is contained is as such:
####### Input URL of ALLOWED_HOSTS in Django's settings ############
variable "allowed_hosts" {
description = "Domain name for allowed hosts"
default = ".example.org"
}
And lastly where I call all these variables to is in my data template for Terraform:
### Here lies the container-definition.json file to input what each container's parameters
### must have.
data "template_file" "ecs-containers" {
template = file("container-definitions/container-def.json")
vars = {
django_docker_image = var.django_docker_image
ngnix_docker_image = var.ngnix_docker_image
rds_db_name = var.rds_db_name
rds_username = var.rds_username
rds_password = var.rds_password
allowed_hosts = var.allowed_hosts
}
}
I would appreciate any feedback on this. I know I'm ALMOST there to fixing the issue. Thanks all.
