# Traefik GitHub OAuth Plugin

> This is a fork of [MuXiu1997](https://github.com/MuXiu1997/traefik-github-oauth-plugin) repository. This fork is mostly fixing some of the security concerns I wanted to address. This will be kept synced with the main repo.

This is a Traefik middleware plugin that allows users to authenticate using GitHub OAuth.

The plugin is intended to be used as a replacement for the BasicAuth middleware,

providing a more secure way for users to access protected routes.

## Quick Start (Docker)

1. Create a GitHub OAuth App

- See: https://docs.github.com/en/developers/apps/building-oauth-apps/creating-an-oauth-app
- Set the Authorization callback URL to `http:///oauth/redirect`

2. Run the Traefik GitHub OAuth server

```sh
docker run -d --name traefik-github-oauth-server \
--network \
-e 'GITHUB_OAUTH_CLIENT_ID=' \
-e 'GITHUB_OAUTH_CLIENT_SECRET=' \
-e 'API_BASE_URL=http://' \
-l 'traefik.http.services.traefik-github-oauth-server.loadbalancer.server.port=80' \
-l 'traefik.http.routers.traefik-github-oauth-server.rule=Host(``)' \
luizfonseca/traefik-github-oauth-server
```

3. Install the Traefik GitHub OAuth plugin

Add this snippet in the Traefik Static configuration

```yaml
experimental:
plugins:
github-oauth:
moduleName: "github.com/luizfonseca/traefik-github-oauth-plugin"
version:
```

4. Run your App

```sh
docker run -d --whoami test \
--network \
--label 'traefik.http.middlewares.whoami-github-oauth.plugin.github-oauth.apiBaseUrl=http://traefik-github-oauth-server' \
--label 'traefik.http.middlewares.whoami-github-oauth.plugin.github-oauth.whitelist.logins[0]=luizfonseca' \
--label 'traefik.http.routers.whoami.rule=Host(`whoami.example.com`)' \
--label 'traefik.http.routers.whoami.middlewares=whoami-github-oauth' \
traefik/whoami
```
