Deploy to Elastic Beanstalk

Deploy to Elastic Beanstalk

This project is just example, you can use it in your final project, but be shure that all other requirements are met.

Create VPC with public and private subnets

Go to VPC → VPCs → Create VPC:

• Resources to create: VPC and more
• VPC endpoints: None
• NAT gateway is paid and is not required here, but recommended for security reasons (and we can use free NAT Instance instead of paid NAT gateway)
• All other settings you can leave as is or customize as you want

Note

Load balancer and RDS require at least 2 subnets in different AZ!

Create Security groups for RDS and instances

Go to VPC → Security → Security groups or EC2 → Network & Security → Security Groups.

Create security groups in your VPC with following rules:

• Security group for EC2 instances:

  • Type: SSH

    Source: Anywhere-IPv4 or My IP

• Security group for RDS instance:

  • Type: PostgreSQL

    Source: choose security group created for EC2 instances

Create RDS with PostgreSQL in private subnet

Go to Aurora and RDS → Subnet groups → Create DB subnet group:

• VPC: Choose your VPC
• Availability Zones: choose all zones where you have created subnets
• Subnets: choose only private subnets

Go to Aurora and RDS → Databases → Create database:

• Choose a database creation method: Standard create
• Engine type: PostgreSQL
• Virtual private cloud (VPC): choose your VPC
• DB subnet group: choose subnet group you have just created
• Public access: No
• VPC security group (firewall): choose existing security group you created for RDS
• The last Additional configuration → Database options → Initial database name fill with your desired name for database which will be used in the DATABASE_NAME variable later (or create database manually)

Create SSH key to securely log in to EC2 instances

If you already have created key pair, you can skip this step

Go to EC2 → Network & Security → Key Pairs → Create key pair

Prepare archive for deployment

Note

Commands below may differ depending on your operating system! python may be python3 or py. Example tested on Linux and MacOS only!

Clone this repository

git clone https://github.com/ReshetS/django-app.git django_app

Go to django_app directory

cd django_app

Create and activate virtual environment, install dependencies

python -m venv .venv --prompt django_app
source .venv/bin/activate
pip install -r requirements.txt

Generate static resources

python manage.py collectstatic

Create archive

zip -r ../django_app.zip . -x '.venv/*' '.git/*' '*__pycache__*'

Create application in Elastic Beanstalk

Configure environment

• Environment tier: Web server environment
• Platform: Python
• Platform branch: Python 3.13 running on 64bit Amazon Linux 2023

Configure service access

• Service role: choose to create new or use existing aws-elasticbeanstalk-service-role (if already exists)
• EC2 instance profile: choose to create new or use existing aws-elasticbeanstalk-ec2-role (if already exists)
• EC2 key pair: choose your key

Set up networking, database, and tags

• Virtual Private Cloud (VPC): choose your VPC

• Instance settings:

  	with NAT gateway	without NAT gateway
  Public IP address	⬜ Activated	☑️ Activated
  Instance subnets	private subnets only	public subnets only

• Database we have already created in previous step so we leave this as is Configure instance traffic and scaling

• Instances:

  • EC2 security groups: choose security group for EC2 instances

• Capacity:

  • Auto scaling group:
    • Environment type: Load balanced

• Load balancer network settings:

  • Visibility: public
  • Load balancer subnets: choose only public subnets

• Load Balancer Type: Application load balancer

Configure updates, monitoring, and logging

• Platform software:
  • Environment properties: create all required environment variables like DJANGO_SECRET_KEY, DJANGO_ALLOWED_HOSTS, DATABASE_HOST and others

Create superuser in django_app

Log in to one of instances and create .env file with appropriate values

export DJANGO_SECRET_KEY=
export DATABASE_NAME=
export DATABASE_USERNAME=
export DATABASE_PASSWORD=
export DATABASE_HOST=

Source this file

source .env

Go to app directory, activate virtualenv and run createsuperuser

cd /var/app/current/
source /var/app/venv/*/bin/activate
python manage.py createsuperuser
