The Trunk GitHub app lets you integrate Merge Queue and Flaky Test features with your GitHub repos. It can help you manage merge queue branches, and post PR comments about your test results. You can install the Trunk GitHub App by navigating to Settings → Organization → GitHub and clicking Install GitHub App. You’ll be redirected to GitHub to select the repositories where the GitHub app will be installed. The Trunk GitHub App enables functionality for all of Trunk’s tools. Not every permission is required for every feature of Trunk, and if you have only enabled one of our tools, we will only access the permissions pertaining to that tool. For complete documentation of the individual permissions the Trunk GitHub App requires, see the GitHub developer docs. Below, find an explanation of every permission the Trunk GitHub App requires and what Trunk uses it for.
Looking for the Trunk Sudo app? Trunk also provides a separate Trunk Sudo GitHub App, used by features that need to merge pull requests while bypassing GitHub branch protections (such as Force merge). It’s optional and only required if you use one of those features.
