# Google OAuth 2.0 OmniAuth Provider **(FREE SELF)**
|
|
|
|
To enable the Google OAuth 2.0 OmniAuth provider you must register your application
|
|
with Google. Google generates a client ID and secret key for you to use.
|
|
|
|
## Enable Google OAuth
|
|
|
|
In Google's side:
|
|
|
|
1. Navigate to the [cloud resource manager](https://console.cloud.google.com/cloud-resource-manager) page
|
|
1. Select **Create Project**
|
|
1. Provide the project information:
|
|
- **Project name** - "GitLab" works just fine here.
|
|
- **Project ID** - Must be unique to all Google Developer registered applications.
|
|
Google provides a randomly generated Project ID by default. You can use
|
|
the randomly generated ID or choose a new one.
|
|
1. Refresh the page and you should see your new project in the list
|
|
1. Go to the [Google API Console](https://console.developers.google.com/apis/dashboard)
|
|
1. Select the previously created project in the upper left corner
|
|
1. Select **Credentials** from the sidebar
|
|
1. Select **OAuth consent screen** and fill the form with the required information
|
|
1. In the **Credentials** tab, select **Create credentials > OAuth client ID**
|
|
1. Fill in the required information
|
|
- **Application type** - Choose "Web Application"
|
|
- **Name** - Use the default one or provide your own
|
|
- **Authorized JavaScript origins** -This isn't really used by GitLab but go
|
|
ahead and put `https://gitlab.example.com`
|
|
- **Authorized redirect URIs** - Enter your domain name followed by the
|
|
callback URIs one at a time:
|
|
|
|
```plaintext
|
|
https://gitlab.example.com/users/auth/google_oauth2/callback
|
|
https://gitlab.example.com/-/google_api/auth/callback
|
|
```
|
|
|
|
1. You should now be able to see a Client ID and Client secret. Note them down
|
|
or keep this page open as you need them later.
|
|
1. To enable projects to access [Google Kubernetes Engine](../user/infrastructure/clusters/index.md), you must also
|
|
enable these APIs:
|
|
- Google Kubernetes Engine API
|
|
- Cloud Resource Manager API
|
|
- Cloud Billing API
|
|
|
|
To do so you should:
|
|
|
|
1. Go to the [Google API Console](https://console.developers.google.com/apis/dashboard).
|
|
1. Click on **ENABLE APIS AND SERVICES** button at the top of the page.
|
|
1. Find each of the above APIs. On the page for the API, press the **ENABLE** button.
|
|
It may take a few minutes for the API to be fully functional.
|
|
|
|
On your GitLab server:
|
|
|
|
1. Open the configuration file.
|
|
|
|
For Omnibus GitLab:
|
|
|
|
```shell
|
|
sudo editor /etc/gitlab/gitlab.rb
|
|
```
|
|
|
|
For installations from source:
|
|
|
|
```shell
|
|
cd /home/git/gitlab
|
|
sudo -u git -H editor config/gitlab.yml
|
|
```
|
|
|
|
1. See [Configure initial settings](omniauth.md#configure-initial-settings) for initial settings.
|
|
1. Add the provider configuration:
|
|
|
|
For Omnibus GitLab:
|
|
|
|
```ruby
|
|
gitlab_rails['omniauth_providers'] = [
|
|
{
|
|
"name" => "google_oauth2",
|
|
"app_id" => "YOUR_APP_ID",
|
|
"app_secret" => "YOUR_APP_SECRET",
|
|
"args" => { "access_type" => "offline", "approval_prompt" => '' }
|
|
}
|
|
]
|
|
```
|
|
|
|
For installations from source:
|
|
|
|
```yaml
|
|
- { name: 'google_oauth2',
|
|
app_id: 'YOUR_APP_ID',
|
|
app_secret: 'YOUR_APP_SECRET',
|
|
args: { access_type: 'offline', approval_prompt: '' } }
|
|
```
|
|
|
|
1. Change `YOUR_APP_ID` to the client ID from the Google Developer page
|
|
1. Similarly, change `YOUR_APP_SECRET` to the client secret
|
|
1. Make sure that you configure GitLab to use a fully-qualified domain name, as
|
|
Google doesn't accept raw IP addresses.
|
|
|
|
For Omnibus packages:
|
|
|
|
```ruby
|
|
external_url 'https://gitlab.example.com'
|
|
```
|
|
|
|
For installations from source:
|
|
|
|
```yaml
|
|
gitlab:
|
|
host: https://gitlab.example.com
|
|
```
|
|
|
|
1. Save the configuration file.
|
|
1. [Reconfigure](../administration/restart_gitlab.md#omnibus-gitlab-reconfigure)
|
|
or [restart GitLab](../administration/restart_gitlab.md#installations-from-source) for
|
|
the changes to take effect if you installed GitLab via Omnibus or from source
|
|
respectively.
|
|
|
|
On the sign in page there should now be a Google icon below the regular sign in
|
|
form. Click the icon to begin the authentication process. Google asks the
|
|
user to sign in and authorize the GitLab application. If everything goes well
|
|
the user is returned to GitLab and is signed in.
