Pulumi Github App

    Pulumi’s GitHub app displays the results of Pulumi stack update previews in pull requests and enables automatic stack deployments via Pulumi Deployments. Once installed and configured, it will show you any potential infrastructure changes on Pull Requests and commit checks. You can also configure git push to deploy workflows that update your stacks whenever a pull request is merged.

    Features

    The Pulumi GitHub app will automatically add comments to Pull Requests with the results of any stack changes. This includes a summary of how many resources were created, updated, and/or deleted. This allows you to quickly see the changes caused by your Pulumi program without needing to leave GitHub’s Pull Request view, with a link to the richer details available on the Pulumi Cloud.

    Comment on Pull Request

    Beyond Pull Request comments, the GitHub application also integrates with GitHub’s Checks API. This provides even more detail about any resource changes, including the full update log.

    Configure Git Push-to-Deploy with Pulumi Deployments

    To set up a git push-to-deploy workflow using Pulumi Deployments, consult the Pulumi Deployments documentation after installing the Pulumi GitHub App.

    CI Integration

    The Pulumi GitHub application will work with any CI/CD system. See our Continuous Delivery guide for information on how to integration Pulumi with whatever system you currently use.

    Once installed in your organization, any pulumi preview or pulumi up that is run in your CI system will have its results reported back to GitHub.

    GitHub UI

    There are two places that Pulumi update results will be displayed: Pull Requests or commit Check.

    All Pulumi stack updates are reported to the GitHub Checks API. You can see the results of each commit check by “Code” tab’s “Commits” page, and then clicking the ✅ or ❌ icon.

    For Pull Requests, you can see the checks on the “Checks” tab as well.

    GitHub Checks Tab

    Every stack that was impacted by the CI job is then listed in the left.

    If the CI build originated from a pull request, e.g. the Travis CI job had type pull_request, then the results will be placed as a comment on the Pull Request as well.
