Backstage Scaffolder Actions for Kubernetes

This is a Kubernetes actions plugin for the scaffolder-backend in Backstage.

It contains a set of actions to create and manage Kubernetes resources.

Getting Started

In the root directory of your Backstage project:

yarn add @devangelista/backstage-scaffolder-kubernetes

Make sure to add a Kubernetes section to your app-config.yaml (check the Backstage docs)

On your package/backend/src/scaffolder.ts file, add the following:

backend.add(import("@devangelista/backstage-scaffolder-kubernetes"));

The scaffolder kube actions should now be available to use on your templates. Check the /create/actions endpoint for documentation.

Usage

You can now use the actions in your templates:
