netlify-cms has its own github OAuth client. This is a python implementation based on the Node.js version.
Other implementations
git clone https://github.com/ericthelemur/decap-cms-oauth-provider.git
cd decap-cms-oauth-provider
python -m pip install pipenv
pipenv install
Configuration is done with environment variables, which can be supplied as command line arguments, added in your app hosting interface, or loaded from a .env file.
Example .env file:
OAUTH_CLIENT_ID=f432a9casdff1e4b79c57
OAUTH_CLIENT_SECRET=pampadympapampadympapampadympa
REDIRECT_URL=https://your.server.com/callback
GIT_HOSTNAME=https://github.website.com
SSL_ENABLED=1
RUN_HOST=127.0.0.1
RUN_PORT=5000
Client ID & Client Secret: After registering your Oauth app, you will be able to get your client id and client secret on the next page.
Redirect URL (optional): Include this if you need your callback to be different from what is supplied in your Oauth app configuration.
Git Hostname (Optional): This is only necessary for use with Github Enterprise.
You also need to add base_url to the backend section of your netlify-cms's config file. base_url is the live URL of this repo with no trailing slashes.
backend:
name: github
repo: user/repo # Path to your Github repository
branch: master # Branch to update
base_url: https://your.server.com # Path to ext auth provider
With your virtual environment activated run the server as follows
pipenv run python main.py
