1. Create a new Django project¶
In this tutorial you will create and deploy a new project using Django, the most popular Python web application framework. The project will be set up in Docker and integrated with various cloud services such as database and media storage.
The principles covered by the tutorial will apply to any other development stack.
This is a step-by-step introduction intended for beginners.
If you’re already familiar with the basics of Divio or have experience with Docker and cloud platforms in general, our guide How to create and deploy a Django project is probably more appropriate.
1.1. Set up a project in the Cloud¶
If you have not already done so, you will need to set up the local development environment.
1.1.1. 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. For convenience we some ready-to-go project types for applications built in Java, PHP, Node and other languages. Use of these is optional. You can also start with a Build your own project, in which you build your application from a blank sheet.
For this tutorial, select the following options for your project (other options should be left on their default settings):
Build your own
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 Continue, then select the free Developer plan for this project (the Developer plan is fully-featured and provides all you need to work on an application up to the point of putting it into production).
It takes a few moments to create the project. During this process, the Control Panel defines the basic project files for your application by adding commits to its repository. This could include assembling its Dockerfile and other files, depending on the project type.
1.1.2. Project environments¶
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.
This project is empty, so though you can try deploying it, that will fail (it will fail because the deployment process checks for a successful start up, and so far, there isn’t anything to start).
1.2. 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.
1.3. 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.
