Applies to Collaborator 12.1, last modified on August 21, 2019

About

  • Collaborator integrates with Git repositories hosted at GitLab.com, or on the GitLab Community or GitLab Enterprise servers in your network.

  • When you integrate Collaborator with a GitLab repository, your Collaborator server creates reviews automatically for pull requests in the repo, as well as for push events that occur in that repo. For complete information on how the integration works, see Integration With Repository Hosting Services.

  • To inform Collaborator about changes, GitLab uses a webhook that sends notification messages to your Collaborator server.

  • To set up the webhook and other integration parameters, you need to set up some options in Collaborator and in GitLab. See the rest of this topic for details.

Supported Hosting Services

  • GitLab (gitlab.com)

  • GitLab Community Edition

  • GitLab Enterprise Edition

Requirements

  • Your Collaborator server must be accessible to GitLab and vice versa. You may need to configure your firewall or enable tunneled connections to expose the server’s External URL to the Web. If needed, ask your system administrator for help.

  • To configure integration settings in Collaborator, you need Administrator privileges.

1. Get GitLab Tokens

To integrate with GitLab, you need a personal access token that will be used to access your repositories.

For detailed information on generating a personal access token, follow instructions on this page of GitLab documentation:

https://gitlab.com/help/user/profile/personal_access_tokens.md

2. Set Up Integration

Collaborator offers two groups of settings for configuring integration with remote repositories:

Settings When to use
Easy Add Repository tab We recommend using these settings to set up new connections to your repositories quickly.
Configure Remote Systems tab Use these settings to configure existing connections. Though you can use these settings to set up integration, the settings on the “Easy Add Repository” tab will help you do this faster.

Easy Add Repository tab (recommended)

  1. Log in to Collaborator as administrator. (To integrate with GitLab repositories, you need administrator privileges in Collaborator).

  2. On the Collaborator main toolbar, click ADMIN, and then select Repository Hosting Services from the tree on the left. Then switch to the Easy Add Repository tab.

  3. On the tab, select GitLab in the Add repository for box and click Next:

    Integration with GitHub: Start

Known Issues and Specifics

  • When configuring user remote accounts, user names must be entered as specified in the Name field of Profile settings. Do not use the Account name.

  • If repository contains a CODEOWNERS file that defines users responsible for certain files in a repository and integration can match those GitHub users with Collaborator users, then it will automatically add those users as reviewers on Collaborator's side.

  • You can secure webhook calls by providing a secret token while creating or modifying a webhook and integration settings in GitLab and in Collaborator. This token will be used as server signature for verifying webhook events. The webhook token is optional and is absent by default.

  • To avoid creating reviews for merge commits, keep their messages default or start them with the Merge branch substring.

  • If a push or merge request in GitLab affects more than 200 files, the integration will process only first 200 files from the request and add those files to a review. This is caused by the limitation on the GitLab API side.

  • Currently, GitLab integration does not support connecting to the target GitLab server through the proxy server.

GitLab Community / GitLab Enterprise
  • By default, GitLab Community / GitLab Enterprise servers do not allow performing webhook requests to web services running in the same local network. If your Collaborator server resides on the same machine as GitLab server or within the same local network, then administrator of your GitLab server should enable the Allow requests to the local network from hooks and services option in the Outbound requests section in Admin > Settings.
