@qtorque/backstage-plugin-torque-backend is a plugin for the Backstage backend app. It provides a route that @qtorque/backstage-plugin-torque is using to communicate with Torque API and scaffolder action to create a service and all needed infrastruction with Torque.

Installation

1. Install @qtorque/backstage-plugin-torque-backend plugin with,

yarn workspace backend add @qtorque/backstage-plugin-torque-backend

2. Create ./packages/backend/src/plugins/torque.ts with the following content,

import { createRouter } from '@qtorque/backstage-plugin-torque-backend';
import { Router } from 'express';
import { PluginEnvironment } from '../types';

export default async function createPlugin(
  env: PluginEnvironment,
): Promise<Router> {
  return await createRouter({
    logger: env.logger,
    config: env.config,
  });
}

3. Add torque api route to ./packages/backend/src/index.ts.

import search from './plugins/search';
+ import torque from './plugins/torque';

const searchEnv = useHotMemoize(module, () => createEnv('search'));
+ const torqueEnv = useHotMemoize(module, () => createEnv('torque'));

const apiRouter = Router();
apiRouter.use('/catalog', await catalog(catalogEnv));
+ apiRouter.use('/torque', await torque(torqueEnv));

4. Add configuration to app-config.yaml

torque:
  token: ${TORQUE_TOKEN} # without Bearer
  executionHost: ${TORQUE_AGENT_NAME} # the name of agent registered in Torque
  serverUrl: ${TORQUE_URL} # default is https://portal.qtorque.io
  ghAccessToken: ${GITHUB_TOKEN} # github token

Scaffolder Actions

This plugin provides the following scaffolder actions:

create-app

create-app will prepare an infrastructure in Torque and create an environment for service.

Installation

To make this action available, you can add it to your scaffolder plugin configuration in ./packages/backend/src/plugins/scaffolder.ts

# import createTorqueApp action
+ import { createTorqueApp } from "@qtorque/backstage-plugin-torque-backend";

# register the action
  const actions = [
    ...builtInActions,
    createTorqueApp({
+      token: config.getString('torque.token'),
+      executionHost: config.getString('torque.executionHost'),
+      ghAccessToken: config.getString('torque.ghAccessToken'),
+      serverUrl: config.getOptionalString('torque.serverUrl')
    })
  ];

Usage

Add the action to your template,

    - name: Deploy with Torque
      id: torque-app-id
      action: torque:create-app
      input:
        serviceName: ${{ parameters.componentName }} # The name of service that will be created in Torque. 
        # Will be used as space, assets repo, blueprint repo and grain names
        assetRepo: ${{ steps.publish.output.remoteUrl }} # The asset repo that will be connected to Torque
        blueprintRepo: ${{ steps.publish.output.remoteUrl }} # The blueprints repo that will be connected to Torque
        serviceAccount: 'default' # A k8s service account to assign to agent
        namespace: default # A k8s namespace to assign to agent
        blueprintName: ${{ parameters.componentName }} # The name of a blueprint you that will be a source for sandbox environment
