Create a new Django project

In this section we will create and deploy a new project in the Control Panel using Django, the most popular Python web application framework. The principles covered by the tutorial will apply to any other development stack.

Note

This tutorial is intended to introduce the basics of working with Divio, using Django as an example. It is not a tutorial for Django. However, you don’t need to know Django or Python, or have them installed on your system.

Set up a project in the Cloud

If you have not already done so, you will need to set up the local development environment.

Create the project

In the Divio Control Panel, create a new project.

Any web application in any language can run on Divio, as long as there is nothing that prevents its being Dockerised. However for convenience we also provide a number of ready-to-go project types for applications built in Java, PHP, Node and other languages (and the list is growing).

Select the following options for your project (other options should be left on their default settings):

  • Python: Python 3.x
  • Project type: Django

Django 2.2

At the time of writing, version 2.2 is Django’s Long-Term Support release, and is guaranteed support until at least April 2022. This is the version currently selected by default in Divio projects.

Divio projects use Git for code management. We provide a Git server that your projects will use by default; you can also choose to use another Git service if you prefer. For this tutorial, use our Git server.

Hit Create. (You may be asked to select a subscription for the project; select the free Developer plan if so.)

It takes a few moments to create the project. During this process, the Control Panel defines the Docker image for your application by adding commits to its repository, assembling its Dockerfile and other files.

Project environments

'Project Dashboard'

Your project has two independent server environments, Test and Live . The Test and Live environments have their own services, and unique environment variables to configure access to them. They can be deployed independently, and can also be configured to track different Git branches.

Deploy the project

Once the project has been fully created, use the Deploy button to deploy the Test server.

The deployment process first builds the Docker image from the Dockerfile, and then launches a Docker container from the image. The container environment will include automatically-configured environment variables for connections to services such as the database, media storage and so on.

Typically, this takes a minute or so.

Open the Test environment website

Once you have successfully deployed the Test environment, the Control Panel will indicate this in the interface:

Last deployment successful at …

and the project URL in the Test environment pane will display as a link, for example https://tutorial-project-stage.us.aldryn.io. Select the link to access the project.

Since this is your own project, you can use our single-sign-on to log in by selecting Log in with Divio. You’ll see the familiar Django admin for a new project.

'Django admin'

The new project doesn’t do anything very useful or interesting yet - but it’s up and running and ready to start working on.

About deployment

Any time new changes to the project code are committed to its repository, the Control Panel will indicate this with a message showing the number of undeployed commits for each of its server environments.

New code and configuration changes applied via the Control Panel (to subscriptions, cron jobs, environment variable, domains or other settings) will not take effect on either server environment until it is deployed once again.

If for whatever reason a deployment fails, there will be no down-time - the containers that are currently running will continue running, and the failing changes will not be deployed.

Explore the Dashboard

The Divio project Dashboard provides you with access to useful controls and information for the project. They are fairly self-explanatory and at this stage you don’t need to interact with any of them, but it’s worth familiarising yourself with what’s available.
