Merge request widgets
The Overview page of a merge request displays status updates from services that perform actions on your merge request. All subscription levels display a widgets area, but the content of the area depends on your subscription level and the services you configure for your project.
Pipeline information
If you’ve set up GitLab CI/CD in your project, a merge request displays pipeline information in the widgets area of the Overview tab:
- Both pre-merge and post-merge pipelines, and the environment information, if any.
- Which deployments are in progress.
If an application is successfully deployed to an environment, the deployed environment and the link to the review app are both shown.
Post-merge pipeline status
When a merge request is merged, you can see the post-merge pipeline status of the branch the merge request was merged into. For example, when a merge request is merged into the default branch and then triggers a deployment to the staging environment.
Ongoing deployments are shown, and the state (deploying or deployed)
for environments. If it’s the first time the branch is deployed, the link
returns a 404 error until done. During the deployment, the stop button is
disabled. If the pipeline fails to deploy, the deployment information is hidden.
For more information, read about pipelines.
Merge when pipeline succeeds (MWPS)
Set a merge request that looks ready to merge to merge automatically when CI pipeline succeeds.
Live preview with Review Apps
If you configured Review Apps for your project, you can preview the changes submitted to a feature branch through a merge request on a per-branch basis. You don’t need to checkout the branch, install, and preview locally. All your changes are available to preview by anyone with the Review Apps link.
With GitLab Route Maps set, the merge request widget takes you directly to the pages changed, making it easier and faster to preview proposed modifications.
