# Configure GitHub OAuth2 authentication

{{< docs/shared lookup="auth/intro.md" source="grafana" version="<GRAFANA VERSION>" >}}

This topic describes how to configure GitHub OAuth2 authentication.

## Before you begin

To follow this guide:

- Ensure that you have access to the [Grafana configuration file]({{< relref "../../../configure-grafana#configuration-file-location" >}}).
- Ensure you know how to create a GitHub OAuth app. Consult GitHub's documentation on [creating an OAuth app](https://docs.github.com/en/apps/oauth-apps/building-oauth-apps/creating-an-oauth-app) for more information.

## Steps

To configure GitHub authentication with Grafana, follow these steps:

1. Create an OAuth application in GitHub.
1. Set the callback URL for your GitHub OAuth app to `http://<my_grafana_server_name_or_ip>:<grafana_server_port>/login/github`.

   Ensure that the callback URL is the complete HTTP address that you use to access Grafana via your browser, but with the appended path of `/login/github`.

   For the callback URL to be correct, it might be necessary to set the `root_url` option in the `[server]`section of the Grafana configuration file. For example, if you are serving Grafana behind a proxy.

1. Refer to the following table to update field values located in the `[auth.github]` section of the Grafana configuration file:

   | Field                        | Description                                                                         |
   | ---------------------------- | ----------------------------------------------------------------------------------- |
   | `client_id`, `client_secret` | These values must match the client ID and client secret from your GitHub OAuth app. |
   | `enabled`                    | Enables GitHub authentication. Set this value to `true`.                            |

   Review the list of other GitHub [configuration options]({{< relref "#configuration-options" >}}) and complete them, as necessary.

1. [Configure role mapping]({{< relref "#configure-role-mapping" >}}).
1. Optional: [Configure team synchronization]({{< relref "#configure-team-synchronization" >}}).
1. Restart Grafana.

   You should now see a GitHub login button on the login page and be able to log in or sign up with your GitHub accounts.

## Configuration options

The table below describes all GitHub OAuth configuration options. Like any other Grafana configuration, you can apply these options as environment variables.

| Setting                      | Required | Description                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 | Default                                       |

| `role_attribute_path`        | No       | [JMESPath](http://jmespath.org/examples.html) expression to use for Grafana role lookup. Grafana will first evaluate the expression using the user information obtained from the UserInfo endpoint. If no role is found, Grafana creates a JSON data with `groups` key that maps to GitHub teams obtained from GitHub's [`/api/user/teams`](https://docs.github.com/en/rest/teams/teams#list-teams-for-the-authenticated-user) endpoint, and evaluates the expression using this data. The result of the evaluation should be a valid Grafana role (`Viewer`, `Editor`, `Admin` or `GrafanaAdmin`).

If this option is set to `false` and the result of evaluating `role_attribute_path` for a user is `GrafanaAdmin`, Grafana grants the user only organization administrator role.

## Configure role mapping

Unless `skip_org_role_sync` option is enabled, the user's role will be set to the role retrieved from GitHub upon user login.

The user's role is retrieved using a [JMESPath](http://jmespath.org/examples.html) expression from the `role_attribute_path` configuration option.
To map the server administrator role, use the `allow_assign_grafana_admin` configuration option.
Refer to [configuration options]({{< relref "#configuration-options" >}}) for more information.

If no valid role is found, the user is assigned the role specified by [the `auto_assign_org_role` option]({{< relref "../../../configure-grafana#auto_assign_org_role" >}}).
You can disable this default role assignment by setting `role_attribute_strict = true`.
This setting denies user access if no role or an invalid role is returned.

To ease configuration of a proper JMESPath expression, go to [JMESPath](http://jmespath.org/) to test and evaluate expressions with custom payloads.

### Role mapping examples

This section includes examples of JMESPath expressions used for role mapping.

#### Map roles using GitHub user information

In this example, the user with login `octocat` has been granted the `Admin` role.
All other users are granted the `Viewer` role.

```bash
role_attribute_path = [login=='octocat'][0] && 'Admin' || 'Viewer'
```

#### Map roles using GitHub teams

In this example, the user from GitHub team `my-github-team` has been granted the `Editor` role.
All other users are granted the `Viewer` role.

```bash
role_attribute_path = contains(groups[*], '@my-github-organization/my-github-team') && 'Editor' || 'Viewer'
```

### Map server administrator role

In this example, the user with login `octocat` has been granted the `Admin` organization role as well as the Grafana server admin role.
All other users are granted the `Viewer` role.

```bash
role_attribute_path = [login=='octocat'][0] && 'GrafanaAdmin' || 'Viewer'
```

## Configure team synchronization

> **Note:** Available in [Grafana Enterprise]({{< relref "../../../../introduction/grafana-enterprise" >}}) and [Grafana Cloud](/docs/grafana-cloud/).

By using Team Sync, you can map teams from your GitHub organization to teams within Grafana. This will automatically assign users to the appropriate teams.
Teams for each user are synchronized when the user logs in.

GitHub teams can be referenced in two ways:

- `https://github.com/orgs/<org>/teams/<slug>`
- `@<org>/<slug>`

For example, `https://github.com/orgs/grafana/teams/developers` or `@grafana/developers`.

To learn more about Team Sync, refer to [Configure team sync]({{< relref "../../configure-team-sync" >}}).

## Example of GitHub configuration in Grafana

This section includes an example of GitHub configuration in the Grafana configuration file.

```bash
[auth.github]
enabled = true
client_id = YOUR_GITHUB_APP_CLIENT_ID
client_secret = YOUR_GITHUB_APP_CLIENT_SECRET
scopes = user:email,read:org
auth_url = https://github.com/login/oauth/authorize
token_url = https://github.com/login/oauth/access_token
api_url = https://api.github.com/user
allow_sign_up = true
auto_login = false
team_ids = 150,300
allowed_organizations = ["My Organization", "Octocats"]
allowed_domains = mycompany.com mycompany.org
role_attribute_path = [login=='octocat'][0] && 'GrafanaAdmin' || 'Viewer'
```
