Creating Dockerfile

Create the Dockerfile file in your project's root folder with the following instructions.

FROM ubuntu:18.04

COPY . /app

WORKDIR /app

RUN apt-get update \
    && apt-get -y upgrade \
    && apt-get install -y python3-pip build-essential manpages-dev libpq-dev postgresql-client

RUN python3 -m pip install -U pip \
    && pip3 install --upgrade setuptools \
    && pip3 install -r /app/requirements.txt

EXPOSE 8000

CMD ["gunicorn", "--bind", "0.0.0.0:8000", "--workers", "3", "--timeout", "120", "--max-requests", "600", "--log-file", "-", "<myapplication>.wsgi:application"]

⚠️ Change the text <myapplication> to the name of your application.

Creating a local Docker image

In the root folder of your project execute the command to create the local image of your application.

docker image build -t <myapplication>:latest .

You can change the latest by your application version.

Uploading image to AWS Elastic Container Registry

After the build completes, tag your image so you can push the image to this repository.

docker tag <myapplication>:latest <aws-container-register-url>.amazonaws.com/<myapplication>:latest

Run the following command to push this image to your newly created AWS repository.

docker push <aws-container-register-url>.amazonaws.com/<myapplication>:latest

AWS App Runner

On the AWS AppRunner page, select "create service", then under "source" link to AWS Elastic Container Registry.

Important tips

• Create your environment variables on the Configure service page;

• Modify the Port to 8000 (or the port that Gunicorn is configured);

• In additional settings, search for "Start command" and enter the migrate command:

python3 /app/manager.py migrate

Custom domains

Once the deployment is complete, you can go to the Custom domains folder and parameterize your application's domain, following the AWS instructions.

Django Application

Be sure to parameterize your application's security settings as follows.

In the settings.py file change the settings.

ALLOWED_HOSTS = ['*', ]

⚠️ Remove the setting below so as not to cause too many redirects error.

SECURE_PROXY_SSL_HEADER = ('HTTP_X_FORWARDED_PROTO', 'https')
SECURE_SSL_REDIRECT = True
