Practice Application Development With React And Django

Install React Bootstrap

Create the tests in preparation for updating the Django user model to use the email address field instead of the user name.

Update the Django user model to use the email address as the username, and add additional fields that will be used by the application to verify the user's email.

Create tests to ensure the user registration endpoint can:

• Create a user

• Create a user with the correct field values

• Returns an error if the name is not provided

• Returns an error if the email is not provided

• Returns an error if the password is not provided

Learn how to mock functions and analyze calls to them.

Make Django pull settings from the environment variables.

Use the Django crypto function to generate a random string that will be used to verify a user's email.  Create tests using Regex to verify the URL strings being sent in emails to the user.

Create tests and code to use Django and Simple JWT to issue access tokens and refresh tokens using the Django REST Framework. 

This lesson will show how to use the REST framework to check that a user is authenticated before providing a response.  This lesson will also show how to create a user serializer to encode user data as an HTTP response.

Create an endpoint to update certain fields in the database, and ensure database update calls are only made when necessary.

Test an HTTP error code is returned when unexpected HTTP methods are used to call the endpoint.

Send an email to a user. Mock the send mail function to ensure it is called and with the proper parameters. General a random string of characters. Use Regex to test strings.  Setup Django to pull settings from the environment variables.

Demonstrate how test driven design makes correcting mistakes quick and easy.

Use try/except statements to get the user for a password reset.

Debugging an issue using the browser inspection tool and console log messages.

Create a Docker image for the backend Django server. Set environment variables in the running container.  Use gunicorn to run Django in a container.

Create an nginx container image to serve static files for the Django administration site.

In this lesson we will configure the Django server to read the STATIC_URL setting from an environment variable or use the default.

In this lesson we will add print statements to show non-sensitive variables when the container is running, to hep with debugging issues.  This lesson will also show how to load container environment variables from a file.

Update the nginx configuration to properly deal with HTTP requests when a page is reloaded or a user goes directly to a specific link on the site.

Discuss the benefits of infrastructure as code, include:

• Allows for deletion of environments and easy recreation, resulting in cost savings.

• A method of disaster recovery or incident response.

• Duplicate environments for other projects.

• Change Management And Documentation

Create an Azure Container Registry using the "az acr" command

Upload container images using docker push to the azure container registry (ACR)

Create an Azure Keyvault

Demonstrate how to span multiple lines for a Powershell command.

Create a Kubernetes ConfigMap to allow reconfiguration of the frontend application image.

Learn how to create an Azure VPN Gateway to allow your development staff to securely access your development environments.

This lesson will show how to set up a private DNS zone and then connect it to a virtual network.

Grant permissions for AKS to interact with the local subnet so Kubernetes can set up a private ingress.

Configure the frontend application to use the internal ingress, and then create a private DNS record to access the application over the VPN.

Deploy the backend Django container that is running Gunicorn.  Debug container issues with kubectl describe pods.  Use the --watch parameter to monitor the status of Kubernetes.

Configure the Django application to read the ALLOWED_HOSTS from an environment variable.  Configure the Django application to use CORS_ALLOWED_ORIGINS, which indicates which origins are valid for making requests to Django.
