Steps
In Port's UI or via the Blueprints API, define a 'Service' blueprint with relevant properties (language, tier, squad) and a 'Deployment' blueprint with a relation pointing to Service
Set the relation type to 'many-to-one' so multiple Deployment entities can reference a single Service entity
Create a GitHub Actions workflow that uses the port-labs/port-github-action to upsert Service entities on push events, mapping repository metadata to blueprint properties via the entity mapping YAML
Add a second workflow step or job to upsert Deployment entities referencing the Service entity identifier in the relation field
Verify in Port's Software Catalog that the Service entities show related Deployment entities in the relation panel
Known gotchas
Port entity identifiers must be stable and unique within a blueprint; using mutable values like branch names as identifiers causes entity duplication on renames
Relation target entities must be ingested before or simultaneously with the source entities; ingesting in reverse order creates dangling relations that are not automatically healed on retry
The Port GitHub Action requires a PORT_CLIENT_ID and PORT_CLIENT_SECRET as repository secrets; these are organization-scoped credentials and must be explicitly granted to each repository
