GitLab

GitLab Slack application (FREE SAAS)

NOTE: The GitLab Slack application is only configurable for GitLab.com. It will not work for on-premises installations where you can configure the Slack slash commands service instead. We're planning to make this configurable for all GitLab installations, but there's no ETA - see #28164.

Slack provides a native application which you can enable via your project's integrations on GitLab.com.

Slack App Directory

The simplest way to enable the GitLab Slack application for your workspace is to install the GitLab application from the Slack App Directory.

Clicking install takes you to the GitLab Slack application landing page where you can select a project to enable the GitLab Slack application for.

Configuration

Alternatively, you can configure the Slack application with a project's integration settings.

Keep in mind that you must have the appropriate permissions for your Slack team to be able to install a new application, read more in Slack's documentation on Adding an app to your workspace.

To enable the GitLab service for your Slack team:

  1. Go to your project's Settings > Integration > Slack application (only visible on GitLab.com).
  2. Select Add to Slack.

That's all! You can now start using the Slack slash commands.

Create a project alias for Slack

To create a project alias on GitLab.com for Slack integration:

  1. Go to your project's home page.
  2. Go to Settings > Integrations (only visible on GitLab.com)
  3. On the Integrations page, select Slack application.
  4. The current Project Alias, if any, is displayed. To edit this value, select Edit.
  5. Enter your desired alias, and select Save changes.

Some Slack commands require a project alias, and fail with the following error if the project alias is incorrect or missing from the command:

GitLab error: project or alias not found

Usage

After confirming the installation, you, and everyone else in your Slack team, can use all the slash commands.

When you perform your first slash command, you are asked to authorize your Slack user on GitLab.com.

The only difference with the manually configurable Slack slash commands is that all the commands should be prefixed with the /gitlab keyword. We are working on making this configurable in the future.

For example, to show the issue number 1001 under the gitlab-org/gitlab project, you would do:

/gitlab gitlab-org/gitlab issue show 1001
