Django Deploy Github

This repository is meant to create and test a fully working Github CI that will deploy a Django app to a generic VPS over SSH.

This is a test project and it's still work in progress. Do NOT use this if you don't know what you are doing.

master and develop branches are protected.
Every modification will be made in branches named feature/<username>/<task-name>.
From those branches, a merge request will be opened to develop.

The Python linter for this project will be Flake8. The auto-formatter for python files will be Black with format on save enabled.

Setup Github Secrets

To work, this project relies on some Github Secrets, here's the list:

PROJECT_NAME: Name used for the main project folder creation on the remote VPS, and used to name configuration files related to this project. Use a lowercase name without spaces (like my_project_name).
DJANGO_APP_NAME: Name of the main django app (folder containing the settings.py file), used to locate the main django folder.
VPS_APPS_BASE_PATH: Base path where you store your webapps inside your VPS (like /home/username/web) WITHOUT trailing /.
VPS_HOST: IP of the VPS where code will be deployed
VPS_PORT: SSH port of the SSH service on the VPS (usually 22 but could be different)
VPS_SSH_KEY: Private Key (PEM) that the CI will use to connect to the VPS. You should generate it doing ssh-keygen -m PEM -t rsa -b 4096, then add to your VPS authorized_hosts the public key.
VPS_USERNAME: Username of the user that will be used to login into the VPS
SETTINGS_DB_HOST: Database host for Django
SETTINGS_DB_NAME: Database name for Django
SETTINGS_DB_PORT: Database port for Django
SETTINGS_DB_USER: Database user for Django
SETTINGS_DEBUG: Debug setting for Django (True/False)
SETTINGS_SECRET_KEY: Django Secret Key

Setup local development environment

Setup Python Virtual Environment, and install dependencies

# Create virtual environment
python3 -m venv venv

# Activate virtual environment
source venv/bin/activate

# Install dependencies
pip install -r requirements.txt

Run black formatter from your terminal to auto fix all "auto-fixable" issues inside python files.

black --exclude=django/venv/ .

Test python files before pushing (if there are errors, the CI will fail and won't deploy anything).
Note: we use pflake8 because that will read flake8 configurations from the pyproject.toml file.

# From the root folder of the project
pflake8 --exclude=django/venv/ --count .
