Introduction:

In this article, we will guide You through the process of setting up Mattermost to manage your GitLab CI/CD pipelines. Mattermost is a cloud-Based platform that allows you to connect with your GitLab account and receive notifications about pipeline jobs without leaving Mattermost. By the end of this article, you will have Mattermost connected to your GitLab account, enabling you to trigger pipeline jobs and stay updated with notifications directly on Mattermost. So, let's get started with the setup process.

Setting Up Mattermost

Before we can begin using Mattermost to manage our GitLab CI/CD pipelines, we need to complete a few initial steps. First, we will sign up for a free cloud account on Mattermost by visiting mattermost.com and clicking "Get Started" in the header. Similarly, we will register for a free cloud account on GitLab by visiting gitlab.com and clicking "Register" in the top right corner. Additionally, it is recommended to add an SSH key to your GitLab account preferences to facilitate pushing changes to your repository later on.

Installing the GitLab Plugin in Mattermost

Once we have both Mattermost and GitLab accounts set up, we can proceed with installing the GitLab plugin in Mattermost. To do this, access the Mattermost menu by clicking the menu icon in the top left corner of your Mattermost cloud account. From the menu, navigate to the Marketplace and search for the GitLab plugin. Once you find it, click "Install" to add the plugin to your account.

Creating an Application in GitLab

In order for Mattermost and GitLab to communicate effectively, we need to Create an application that is authorized to connect to our GitLab account on Mattermost. To do this, we will refer to the documentation provided for the GitLab plugin in Mattermost. The documentation will guide us through filling out the necessary fields, including the redirect URI, scopes, and other required information. It is important to ensure that the correct scopes, such as API and Read user, are set for the application to function correctly and access the required resources.

Enabling the GitLab Plugin in Mattermost

After completing the application setup in GitLab, we need to enable the GitLab plugin in Mattermost. To do this, go back to your Mattermost cloud account and navigate to the System Console by clicking the menu icon in the top left corner. Search for the GitLab plugin in the System Console and once you find it, enable it. This step is necessary to finalize the connection between the GitLab application and Mattermost.

Finalizing the Connection between Mattermost and GitLab

In order to confirm that the setup is complete and Mattermost is successfully connected to our GitLab account, we will use a slash command provided by the GitLab plugin. By typing "/get lab connect" in the Mattermost Channel, we will receive a link that allows us to authorize the connection. Clicking the authorize button on the GitLab authorization page will finalize the connection and provide us with a direct message from the GitLab plugin, confirming that the application was set up successfully.

Connecting GitLab Pipeline and Mattermost

With the connection between Mattermost and GitLab established, we can begin using the GitLab plugin to Interact with our GitLab CI/CD pipelines. Using the "git lab me" command, we can confirm that our actual profile has been connected to the plugin. Next, we will navigate to GitLab's Website and create a new pipeline by going to our repository and selecting the CI/CD Pipelines section. This will generate a new YAML file with a contrived example of a CI/CD pipeline in GitLab. Committing this file to our repository will trigger the pipeline to start running.

Interacting with GitLab Pipeline from Mattermost

Once our pipeline is running, we can go back to Mattermost and receive updates about the pipeline progress. The GitLab plugin in Mattermost will notify us when the pipeline starts and finishes, providing detailed information about the stages and jobs involved. We can click on the messages in Mattermost to view the pipeline and its components in GitLab. This bidirectional communication allows us to stay updated with pipeline updates without leaving the Mattermost environment.

Bidirectional Communication between Mattermost and GitLab

In addition to receiving updates about pipeline progress, it would be beneficial to have the ability to trigger jobs from within Mattermost. To enable this functionality, we can set up an integration in GitLab that allows us to send information directly from Mattermost using slash commands. By configuring the Mattermost slash commands in GitLab settings, we can create a custom slash command trigger word and associate it with the Mattermost instance. This integration will enhance our ability to interact with GitLab pipeline jobs directly from Mattermost.

Conclusion

In this article, we have covered the step-by-step process of setting up Mattermost to manage GitLab CI/CD pipelines. We have walked through the initial setup of Mattermost and GitLab accounts, installation of the GitLab plugin in Mattermost, creation of an application in GitLab, enabling the GitLab plugin in Mattermost, and finalizing the connection between Mattermost and GitLab.
