Django-LocalStack

A detailed example and guide for integrating with S3 cloud storage. We're going to connect cloud storage to:

  1. Django admin
  2. Serve static files using S3
  3. Access cloud storage via APIs (DRF)
  4. Access secure content via pre-signed URLs
  5. Show-case large file handling
  6. Writing unit tests using Moto
  7. CloudFront pre-signed URLs - https://django-storages.readthedocs.io/en/latest/backends/amazon-S3.html#cloudfront-signed-urls

Introduction

You'll learn how to integrate these two:

  1. LocalStack-S3
  2. Django-Storages
  3. Moto (Mock for Boto3)

Set-up locally

Ensure you have the following installed on your system:

  1. Docker
  2. LocalStack - We recommend brew install or pip install to get LocalStack on your machine. As long as you have Docker installed, everything should just work

Create a super user for test purposes: python manage.py createsuperuser

Easy commands

    awslocal s3api create-bucket --bucket "django-localstack"
    localstack status services
    awslocal s3api list-objects --bucket django-localstack

    docker network create django-localstack
    docker network connect django-localstack localstack-main

    docker build . -t django-localstack --load && \
    docker run --network django-localstack -p 8000:8000 \
    -v $(pwd):/code/ -t django-localstack

    docker network connect django-localstack django-localstack

Topics to cover

  1. What happens without cloud storage?

    • Gets stored in local file storage or wherever you point it.
    • Replaces creates new stuff
    • Deletes don't delete the actual file

  2. Demonstrate how to configure LocalStack for the project.

    • It's very easy.

  3. Demonstrate how to serve static files using cloud storage.

    • There are optimizations to be made here, but it is what it is.
    • Make Debug=False
