cnoe-io/plugin-scaffolder-actions

Getting Started

Add to your Backstage app.

# From your Backstage root directory
yarn add --cwd packages/backend @cnoe-io/scaffolder-actions-plugin

# To be able to keep using the built-in actions.
yarn add --cwd packages/backend @backstage/integration

Append it to your existing actions in packages/backend/src/plugins/scaffolder.ts

import { CatalogClient } from '@backstage/catalog-client';
import { createRouter, createBuiltinActions } from '@backstage/plugin-scaffolder-backend';
import { ScmIntegrations } from '@backstage/integration';
import { Router } from 'express';
import type { PluginEnvironment } from '../types';
import {
  createSanitizeResource,
  createVerifyDependency,
  createKubernetesApply,
} from "@cnoe-io/scaffolder-actions";

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 cnoeActions = [
    createSanitizeResource(),
    createVerifyDependency(),
    createKubernetesApply(env.config),
  ]

  const actions = [
      ...builtInActions,
      ...cnoeActions,
  ]

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

Done! You can now use any of the action in your software templates.
