      Kargo CLI Namespace Error When Creating a Warehouse

      Understanding the namespace requirement for Kargo projects

      When creating a Warehouse using the Kargo CLI, you may encounter the following error:

      kargo create -f core/kargo/dupapp/warehouse.yaml
      Error: create resource: not_found: namespaces "my-app" not found

      Cause of the Issue

      • Kargo projects are tightly coupled with namespaces.

      • The namespace where the Warehouse is created must match the project name.

      Solution

      1. Verify that the Project name matches the Namespace:
        If your project is named my-app, ensure your Warehouse definition refers to the same namespace.

      2. Create the Warehouse again:

        kargo create -f core/kargo/dupapp/warehouse.yaml

      Key Takeaway

      For Kargo, the Project name and the Namespace must be the same. If you’re getting a "namespace not found" error, manually create the namespace first before applying resources.
