craigwongva / oauth-go Goto Github PK

1. Sign in to GitHub and go to Settings, Oauth Applications.

2. For "Authorization Callback URL", specify "http://12.13.14.15:8888/callmebacktomorrow" (this must match oauthproxy.go line 645 as described below).

3. From ssh session one, run the trivial Go server. It's listening on :8888.

clientid=<your GitHub app client id>
clientsecret=<your GitHub app client secret>
cd ~/oauth-go
./bin/jquery $clientid $clientsecret

4. Get oauth2_proxy

cd ~/oauth-go
go get github.com/bitly/oauth2_proxy

5. Make sure the oauth2-proxy will forward the correct callback_uri.

1. Force oauthproxy.go line 645 to "http://12.13.14.15:8888/callmebacktomorrow" (TODO: This manual override is necessary, but why?)
2. go install github.com/bitly/oauth2_proxy
3. Update the GitHub settings to that same string. This allows the browser access to a further GitHub authorization you-choose-‘em page.

6. From ssh session two, run oauth2-proxy. It's listening on :4180.

cd ~/oauth-go
clientid=<your GitHub app client id>
clientsecret=<your GitHub app client secret>
./cli-oauth2_proxy $clientid $clientsecret

7. From a browser, start the authentication sequence.

http://12.13.14.15:8887

nginx is listening on :8887, authenticates (TODO: authentication is redundant, actually superfluous, so remove this), forwards to oauth2_proxy, which forwards to GitHub, which returns a code to your app via the callback URL, your app sends the code back to GitHub and receives an access_token (TODO: where?), your app uses the access_token to make a GitHub API call.

If your app was only using GitHub for authentication and cared nothing about GitHub itself, then your app would then manage your application's authorizations

TODO: Incorporate something equivalent to the AWS federation login S3 example.
