In this tutorial, we’ll look at how to deploy a Django app to AWS ECS with Terraform.
By the end of this tutorial, you will be able to:
Terraform is an infrastructure as code (IaC) tool used for building, changing, and versioning infrastructure through code. It uses a high-level declarative configuration language that lets you describe the desired state of your cloud or on-prem infrastructure for running an application. Think of it as the single source of truth for your infrastructure, which makes it easy to create, update, and delete resources safely and efficiently. After describing the end state of your infrastructure, Terraform generates a plan and then executes it – e.g., provision and spin up the necessary infrastructure.
In this tutorial, using Terraform, we’ll develop the high-level configuration files required to deploy a Django application to ECS. Once configured, we’ll run a single command to set up the following AWS infrastructure:
Amazon’s Elastic Container Service (ECS) is a fully managed container orchestration platform that’s used to manage and run containerized applications on clusters of EC2 instances.
If you’re new to ECS, it’s recommended to experiment with it in the web console first. Rather than configuring all the underlying network resources, IAM roles and policies, and logs manually, let ECS create these for you. You’ll just need to set up ECS, a Load Balancer, Listener, Target Group, and RDS. Once you feel comfortable then move on to an infrastructure as code tool like Terraform.
Let’s start by setting up a quick Django project.
Create a new project directory along with a new Django project:
$ mkdir django-ecs-terraform && django-ecs-terraform $ mkdir app && cd app $ python3.8 -m venv env $ source env/bin/activate (env)$ pip install django==3.1 (env)$ django-admin.py startproject hello_django . (env)$ python manage.py migrate (env)$ python manage.py runserver
Navigate to http://localhost:8000/ to view the Django welcome screen. Kill the server once done, and then exit from the virtual environment. Go ahead and remove it as well. We now have a simple Django project to work with.
Add a requirements.txt file:
Add a Dockerfile as well:
## pull official base image FROM python:3.8.5-slim-buster ## set work directory WORKDIR /usr/src/app ## set environment variables ENV PYTHONDONTWRITEBYTECODE 1 ENV PYTHONUNBUFFERED 1 ## install dependencies RUN pip install --upgrade pip COPY ./requirements.txt . RUN pip install -r requirements.txt ## copy project COPY . .
For testing purposes, set
True and allow all hosts in the settings.py file:
DEBUG = True ALLOWED_HOSTS = ['*']
Next, build and tag the image and spin up a new container:
$ docker build -t django-ecs . $ docker run \ -p 8007:8000 \ --name django-test \ django-ecs \ gunicorn hello_django.wsgi:application --bind 0.0.0.0:8000
Ensure you can view the welcome screen again at http://localhost:8007/.
Stop and remove the container once done:
$ docker stop django-test $ docker rm django-test
Add a .gitignore file to the project root:
__pycache__ .DS_Store *.sqlite3
Your project structure should now look like this:
├── .gitignore └── app ├── Dockerfile ├── hello_django │ ├── __init__.py │ ├── asgi.py │ ├── settings.py │ ├── urls.py │ └── wsgi.py ├── manage.py └── requirements.txt

Welcome to my blog , hey everyone in this article you learn how to customize the Django app and view in the article you will know how to register and unregister models from the admin view how to add filtering how to add a custom input field, and a button that triggers an action on all objects and even how to change the look of your app and page using the Django suit package let’s get started.

Welcome to my blog, hey everyone in this article we are going to be working with queries in Django so for any web app that you build your going to want to write a query so you can retrieve information from your database so in this article I’ll be showing you all the different ways that you can write queries and it should cover about 90% of the cases that you’ll have when you’re writing your code the other 10% depend on your specific use case you may have to get more complicated but for the most part what I cover in this article should be able to help you so let’s start with the model that I have I’ve already created it.

let’s just get into this diagram that I made so in here:
Describe each parameter in Django querset
we’re making a simple query for the myModel table so we want to pull out all the information in the database so we have this variable which is gonna hold a return value and we have our myModel models so this is simply the myModel model name so whatever you named your model just make sure you specify that and we’re gonna access the objects attribute once we get that object’s attribute we can simply use the all method and this will return all the information in the database so we’re gonna start with all and then we will go into getting single items filtering that data and go to our command prompt.
Here and we’ll actually start making our queries from here to do this let’s just go ahead and run** Python manage.py shell** and I am in my project file so make sure you’re in there when you start and what this does is it gives us an interactive shell to actually start working with our data so this is a lot like the Python shell but because we did manage.py it allows us to do things a Django way and actually query our database now open up the command prompt and let’s go ahead and start making our first queries.

Learn How to Deploy Django to AWS ECS with Terraform 2021 (Step by Step)
By the end of this tutorial, you will be able to:
Terraform is a tool for building, changing, and versioning infrastructure safely and efficiently. Terraform can manage existing and popular service providers as well as custom in-house solutions.
#terraform-aws #terraform #aws #aws-ec2
We’re continuing our series on Terraform AWS with a post that breaks down the basics. The world of Terraform AWS can be described as complex — from AWS storage to AWS best practices, there’s a depth of knowledge necessary to get familiar with Terraform AWS.
Whether you’re an expert at Terraform AWS or just getting started, it’s our goal at InfraCode to provide you with clear and easy-to-understand information at every level. The number of resources out there is abundant but overwhelming. That’s why we create simplified guides that are immediately usable and always understandable.
In this article, we’ll dive into:
