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 --cwd packages/backend @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:

import { kubernetesActions } from '@devangelista/backstage-scaffolder-kubernetes';

export default async function createPlugin(
  env: PluginEnvironment,
): Promise<Router> {
  const catalogClient = new CatalogClient({ discoveryApi: env.discovery });
  const integrations = ScmIntegrations.fromConfig(env.config);

  const builtInActions = createBuiltinActions({
    integrations,
    catalogClient,
    config: env.config,
    reader: env.reader,
  });

  const actions = [...builtInActions, ...kubernetesActions()]; // <-- add this line

  return await createRouter({
    actions,
    catalogClient,
    logger: env.logger,
    config: env.config,
    database: env.database,
    reader: env.reader,
    identity: env.identity,
  });
}

Usage

You can now use the actions in your templates:
