@janus-idp/backstage-scaffolder-backend-module-kubernetes v1.4.5

Kubernetes actions for Backstage

This module provides Backstage template actions for Kubernetes.

The following actions are currently supported in this module:

• Create a kubernetes namespace

Installation

Run the following command to install the action package in your Backstage project

yarn workspace backend add @janus-idp/backstage-scaffolder-backend-module-kubernetes

Installing the action on the legacy backend

1. Register the Kubenretes actions by modifying the packages/backend/src/plugins/scaffolder.ts file from your project with the following changes:

   import { CatalogClient } from '@backstage/catalog-client';
   import { ScmIntegrations } from '@backstage/integration';
   import {
     createBuiltinActions,
     createRouter,
   } from '@backstage/plugin-scaffolder-backend';
   
   import { Router } from 'express';
   
   import { createKubernetesNamespaceAction } from '@janus-idp/backstage-scaffolder-backend-module-kubernetes';
   
   import type { PluginEnvironment } from '../types';
   
   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,
       createKubernetesNamespaceAction(catalogClient),
     ];
   
     return await createRouter({
       actions,
       logger: env.logger,
       config: env.config,
       database: env.database,
       reader: env.reader,
       catalogClient,
       identity: env.identity,
     });
   }

2. Optional: If you are doing the previous step for the first time, you also have to install the @backstage/integration package

   yarn workspace backend add @backstage/integration

Installing the action on the new backend

Add the following to your packages/backend/src/index.ts file:

const backend = createBackend();

// Add the following line
backend.add(
  import('@janus-idp/backstage-scaffolder-backend-module-kubernetes/alpha'),
);

backend.start();

Configuration

  namespace: foo
  clusterRef: bar
