Traefik GitHub OAuth Plugin

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://<traefik-github-oauth-server-host>/oauth/redirect

2. Run the Traefik GitHub OAuth server

   docker run -d --name traefik-github-oauth-server \
     --network <traefik-proxy-network> \
     -e 'GITHUB_OAUTH_CLIENT_ID=<client-id>' \
     -e 'GITHUB_OAUTH_CLIENT_SECRET=<client-secret>' \
     -e 'API_BASE_URL=http://<traefik-github-oauth-server-host>' \
     -l 'traefik.http.services.traefik-github-oauth-server.loadbalancer.server.port=80' \
     -l 'traefik.http.routers.traefik-github-oauth-server.rule=Host(`<traefik-github-oauth-server-host>`)' \
     muxiu1997/traefik-github-oauth-server
   

3. Install the Traefik GitHub OAuth plugin

   Add this snippet in the Traefik Static configuration

   experimental:
     plugins:
       github-oauth:
         moduleName: "github.com/MuXiu1997/traefik-github-oauth-plugin"
         version: <version>
   

4. Run your App

   docker run -d --whoami test \
     --network <traefik-proxy-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]=MuXiu1997' \
     --label 'traefik.http.routers.whoami.rule=Host(`whoami.example.com`)' \
     --label 'traefik.http.routers.whoami.middlewares=whoami-github-oauth' \
    traefik/whoami

Middleware Configuration

# The base URL of the Traefik GitHub OAuth server
apiBaseUrl: http://<traefik-github-oauth-server-host>
# The api secret key. You can ignore this if you are using the internal network
apiSecretKey: optional_secret_key_if_not_on_the_internal_network
# The path to redirect to after the user has authenticated, defaults to /_auth
# Note: This path is not GitHub OAuth App's Authorization callback URL
authPath: /_auth
# optional jwt secret key, if not set, the plugin will generate a random key
jwtSecretKey: optional_secret_key
# The log level, defaults to info
# Available values: debug, info, warn, error
logLevel: info
# whitelist
whitelist:
  # The list of GitHub user ids that in the whitelist
  ids:
    - 996
