GitHub workflow

The GitHub backend allows you to trigger GitHub workflows for your self-service actions and automations, using Port's GitHub application.

GitHub app types

The GitHub backend is available for both the standard Port GitHub app, and the self-hosted version.

The steps shown in the image above are as follows:

  1. Port publishes an invoked action message to a topic.
  2. A secure topic (ORG_ID.github.runs) holds all the action invocations.
  3. A listener implemented in Port's GitHub application receives the new topic message and runs the GitHub workflow defined by the creator of the self-service action/automation.

An example flow would be:

  1. A developer asks to deploy a new version of an existing Microservice, using a self-service action.
  2. The create action is sent to the github.runs topic.
  3. Port's GitHub application event handler is triggered by this new action message.
  4. Port's GitHub application triggers the GitHub workflow that deploys a new version of the service.
  5. As part of the workflow, the new microservice Deployment is reported back to Port.
  6. When the workflow is done, Port's GitHub application reports back to Port about the status of the action run (SUCCESS or FAILURE), according to workflow's status.
triggering workflow chains

A workflow triggered using the workflow_dispatch trigger is self-contained. This means its actions and effects over the repository cannot trigger other automatic workflows.

  1. A developer invokes a "provision new microservice in monorepo" workflow.
  2. The workflow opens a new PR in the target repository based on a pre-defined template.
  3. The repository also has a workflow which is automatically triggered using the on: pull_request: types: "opened" trigger.
  4. In this instance, the automatic PR workflow will not be triggered.


When using this backend, you need to provide the GitHub organization and repository where the workflow is located, as well as the workflow name.
The workflow must reside in the repository's .github/workflows/ directory.

Automatic workflow status update

Additionally, you can define whether or not Port should automatically use the workflow's end status (SUCCESS/FAILURE) to update the action/automation status in Port.

By default, this is set to true. To disable this option, set the reportWorkflowStatus field to true in the invocationMethod object, or set the Report workflow status option to No if using the UI.


See the examples page for implementations of various use-cases using a Github workflow backend.
