Gitlab Authentication Flow Example With Ruby Webrick Webserver
217
This tutorial will use Ruby in the Authentication Flow example app for Gitlab Apps.
This flow first gets a code from the Gitlab Accounts Service, then exchanges that code for an access token. The code-to-token exchange requires a secret key, and for security is done through direct server-to-server communication. In this example we retrieve data from the Web API /user endpoint, that includes information about the current user.
Here we will use Ruby for server-side applications.
First you need to clone the repository.
$ git clone https://github.com/azolf/gitlab-web-api-auth-examples-ruby.git
Then you should go to the directory and install the required Gems.
$ cd gitlab-web-api-auth-examples-ruby/
$ bundle install
You could edit the Gitlab Client Id and Client Secret in initializers/ruby_oauth.rb file.
RubyOuath.configure do |c|
c.scopes = %w[read_user].join(' ')
c.client_id = ENV['CLIENT_ID']
c.client_secret = ENV['CLIENT_SECRET']
c.provider = 'Gitlab'
end
Or you could pass them as environemnt variables.
$ CLIENT_ID=YOUR_CLIENT_ID CLIENT_SECRET=YOUR_CLIENT_SECRET ruby server.rb
You could also use pre built docker image.
$ docker pull azolf/gitlab-web-api-auth-examples-ruby
$ docker run -itd \
--name gitlab-web-api-auth-examples-ruby \
-p 8000:8000 \
-e CLIENT_ID=YOUR_CLIENT_ID \
-e CLIENT_SECRET=YOUR_CLIENT_SECRET \
azolf/gitlab-web-api-auth-examples-ruby:latest
You could also clone the repository and start the container with the docker-compose.yml file. You just need to replace your Client Id and Client Secret in it.
version: '3'
services:
app:
image: azolf/gitlab-web-api-auth-examples-ruby
container_name: gitlab-web-api-auth-examples-ruby
ports:
- 8000:8000
environment:
- CLIENT_ID=YOUR_CLIENT_ID
- CLIENT_SECRET=YOUR_CLIENT_SECRET
$ docker-compose up -d
Then, open http://localhost:8000 in a browser.
