Create a virtual Python environment for the Django project[edit]

Install virtualenv if needed: 

$ which virtualenv
$ pip install virtualenv

Create the virtual Python Environment[1] 

$ virtualenv -p python3.4 /path/to/project_venv

Where /path/to/project_env is a path unique to the project.

Start the virtual environment: 

$ . /path/to/project_venv/bin/activate

Confirm the Python version: 

$ python --version

Leave the virtual environment: 

$ deactivate

Create a Django application locally[edit]

  • Install all prerequisites necessary for the Django app, e.g. Python, pip, Django, etc.
  • See Working With Django Projects, The Basics
  • Run and test the Django application locally, e.g. with python manage.py runserver.

Install AWS Elastic Beanstalk CLI [2][edit]

Install the AWS Elastic Beanstalk cli:

N.B. See the Troubleshooting article for issues installing awsebcli on Mac OS X. 

$ pip install awsebcli

Confirm the installation with eb --version

At this point the directory is ready to have an Elastic Beanstalk application created with eb init. See Deploying a Django app on AWS.
