A simple demonstration of how a django-based website can be set up for local development with microk8s

Overview

Django with MicroK8s

Start Building Your Project

This project provides a Django web app running as a single node Kubernetes cluster in microk8s. It is meant to make it as easy as possible to begin building a project with a minimum of initial configuration.

This is both a reference and an actual github template that can be used to quickly start development. After installing prerequisites and downloading this repository, only one command is needed to have a working, browsable application.

Provided Tools

Prerequisites

You'll need to install the following software:

Note that the system has only been tested on Ubuntu 18+, but should theoretically work for any host OS on which Microk8s and docker can be installed.

Initial Operation

  1. Install pre-requisites.

  2. Download the repository:

    git clone [email protected]:bluemoo/django-with-microk8s.git
    
  3. Install pre-commit hooks:

    pre-commit install
    
  4. Start Microk8s and enable required add-ons:

    microk8s.start
    microk8s enable helm3 dns storage registry host-access ingress
    
  5. Start the system:

    ./dev.sh start
    
  6. Check for successful startup with:

    ./dev.sh status
    
  7. Navigate to http://localhost:8000 and you should see Django tell you it was installed successfully!

Example System Start

$ microk8s.start
Started.

$ microk8s enable helm3 dns storage registry host-access ingress

Development Workflows

dev.sh

The project comes with a shell script dev.sh that contains helpful commands to interact with the running system. In particular, it has options to install/uninstall the system, run django management commands, and run django tests. For a full set of options, simply type: ./dev.sh help

Hot code reloading

The development server mounts files directly from your file system, so any changes to python files will be automatically noticed and result in the server automatically reloading the code:

$ ./dev.sh server-logs
10.1.97.1 - - [11/May/2021 18:33:12] "GET / HTTP/1.1" 200 -
10.1.97.1 - - [11/May/2021 18:33:12] "GET / HTTP/1.1" 200 -
 * Detected change in '/opt/project/server/appsecrets.py', reloading
 * Restarting with stat
Performing system checks...

System check identified no issues (0 silenced).

Django version 3.2.2, using settings 'settings'
Development server is running at http://0.0.0.0:8000/
Using the Werkzeug debugger (http://werkzeug.pocoo.org/)
Quit the server with CONTROL-C.

Thus, you can edit, save, and see your changes in your app very quickly.

Database migrations

As this is a development environment, migrations are automatically applied on system start up, so you'll have an empty django database schema from the beginning. You can perform all other database interactions as you would normally via the Django manage command provided by dev.sh:

$ ./dev.sh manage makemigrations
No changes detected

$ ./dev.sh manage migrate
Operations to perform:
  Apply all migrations: admin, auth, contenttypes, sessions
Running migrations:
  No migrations to apply.

Testing

While django tests can be run via the manage command, the dev.sh file provides a small shortcut, allowing you to simply use ./dev.sh test. You can also pass one or more test labels:

$ ./dev.sh test
...
----------------------------------------------------------------------
Ran 3 tests in 0.001s

OK
System check identified no issues (0 silenced).
$ ./dev.sh test tests.test_appsecrets.AppSecretsIntegrationTest
.
----------------------------------------------------------------------
System check identified no issues (0 silenced).
Ran 1 test in 0.000s

OK

Next steps

This development environment should server you well until you're ready to actually deploy your app to production. However, if you're new to Django, you can easily pick up the tutorial from Creating the Polls app. Just remember that instead of typing python manage.py startapp polls you should use ./dev.sh manage startapp polls instead. Good luck!

Notes

If you want to run docker as non-root user then you need to add it to the docker group. https://stackoverflow.com/questions/48957195/how-to-fix-docker-got-permission-denied-issue
