Steps
In Port, create a self-service action on the Service blueprint with input properties for environment name and region, and set the invocation method to GitHub
Configure the action to dispatch a specific GitHub Actions workflow via the repository dispatch or workflow dispatch event, mapping Port action inputs to workflow inputs
In the GitHub Actions workflow, add steps to provision the environment (e.g., run Terraform or call a cloud API) and capture the resulting endpoint URL as an output
At the end of the workflow, use the Port API to PATCH the action run with a status of 'SUCCESS' or 'FAILURE' and include a summary message and the provisioned URL as a link
Verify in Port that the action run log shows the correct status and that any entity updates triggered by the workflow are reflected in the catalog
Known gotchas
Port action runs have a timeout; if the GitHub Actions workflow runs longer than the configured timeout, Port marks the run as failed even if the workflow eventually succeeds
The Port API token used to update the action run must have write permissions on the action run resource; using a read-only token silently fails the PATCH with a 403
Workflow dispatch inputs are strings; Port action inputs of type boolean or number must be explicitly cast in the workflow before use to avoid unexpected behavior
