sentry-auth-gitlab-v2 0.6.0

Gitlab authentication provider for Sentry

Disclaimer 1

That's a second level for of this library. This fork was made in order to prepare PyPi package and make installation process easier via supported plugins install flow. Original fork disclaimer is below.

Disclaimer 2

I am NOT a python developer. I just changed what was necessary to make it work. This repository can be used directly or be an inspiration to others to enable Gitlab SSO with Sentry 10. These files can be installed from local folder only as no updated package is available in pip repository.

Gitlab configuration

Tested with an official sentry/self-hosted installation:

• Sentry 25.3.0
• Gitlab 17.1

Create a new application under your GitLab. Enter the Callback URL as the prefix to your Sentry installation:

http(s?)://sentry.example.com/auth/sso/

Once done, grab your API keys and drop them in your sentry.conf.py:

GITLAB_APP_ID = "APP-ID"
GITLAB_APP_SECRET = "APP-SECRET"
GITLAB_BASE_DOMAIN = "git.example.com"

Optionally you may also specify the api version, scheme, and scope:

GITLAB_API_VERSION = 4
GITLAB_HTTP_SCHEME = "https"
GITLAB_AUTH_SCOPE = "api"
GITLAB_AUTH_GROUPS = ["my-group", "another-group"]  # restrict login to members of these groups

Notice

If your gitlab is deployed in a private network (probably). You need to alter sentry's default ip black list to make oauth flow work.

Put following config in your sentry.conf.py and delete conflict ones
