sonarqube-backend

Welcome to the sonarqube-backend backend plugin!

New Backend System

The Sonarqube backend plugin has support for the new backend system, here's how you can set that up:

In your packages/backend/src/index.ts make the following changes:

  import { createBackend } from '@backstage/backend-defaults';
  const backend = createBackend();
  // ... other feature additions
+ backend.add(import('@backstage-community/plugin-sonarqube-backend'));
  backend.start();

Integrating into a backstage instance

This plugin needs to be added to an existing backstage instance.

# From your Backstage root directory
yarn --cwd packages/backend add @backstage-community/plugin-sonarqube-backend

Typically, this means creating a src/plugins/sonarqube.ts file and adding a reference to it to src/index.ts in the backend package.

sonarqube.ts

import {
  createRouter,
  DefaultSonarqubeInfoProvider,
} from '@backstage-community/plugin-sonarqube-backend';
import { Router } from 'express';
import { PluginEnvironment } from '../types';

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

   const service = createServiceBuilder(module)

This plugin must be provided with a SonarqubeInfoProvider, this is a strategy object for finding Sonarqube instances in configuration and retrieving data from an instance.

There is a standard one provided (DefaultSonarqubeInfoProvider), but the Integrator is free to build their own.

DefaultSonarqubeInfoProvider

Allows configuration of either a single or multiple global Sonarqube instances and annotating entities with the instance name. This instance name in the entities is optional, if not provided the default instance in configuration will be used. That allow to keep configuration from before multiple instances capability to keep working without changes.

Example - Single global instance

Config

sonarqube:
  baseUrl: https://sonarqube.example.com
  apiKey: 123456789abcdef0123456789abcedf012

Catalog

apiVersion: backstage.io/v1alpha1
kind: Component
metadata:
  name: backstage
  annotations:
    sonarqube.org/project-key: YOUR_INSTANCE_NAME/YOUR_PROJECT_KEY

Example - Multiple global instance

The following will look for findings at https://special-project-sonarqube.example.com for the project of key YOUR_PROJECT_KEY.

Config

sonarqube:
  instances:
    - name: default
      baseUrl: https://default-sonarqube.example.com
      apiKey: 123456789abcdef0123456789abcedf012
    - name: specialProject
      baseUrl: https://special-project-sonarqube.example.com
      apiKey: abcdef0123456789abcedf0123456789ab

Catalog

apiVersion: backstage.io/v1alpha1
kind: Component
metadata:
  name: backstage
  annotations:
    sonarqube.org/project-key: specialProject/YOUR_PROJECT_KEY

If the specialProject/ part is omitted (or replaced with default/), the Sonarqube instance of name default will be used.

The following config is an equivalent (but less clear) version of the above:

sonarqube:
  baseUrl: https://default-sonarqube.example.com
  apiKey: 123456789abcdef0123456789abcedf012
  instances:
    - name: specialProject
      baseUrl: https://special-project-sonarqube.example.com
      apiKey: abcdef0123456789abcedf0123456789ab

Example - Different frontend and backend URLs

In some instances, you might want to use one URL for the backend and another for the frontend. This can be achieved by using the optional externalBaseUrl property in the config.

Single instance config

sonarqube:
  baseUrl: https://sonarqube-internal.example.com
  externalBaseUrl: https://sonarqube.example.com
  apiKey: 123456789abcdef0123456789abcedf012

Multiple instance config

sonarqube:
  instances:
    - name: default
      baseUrl: https://default-sonarqube-internal.example.com
      externalBaseUrl: https://default-sonarqube.example.com
      apiKey: 123456789abcdef0123456789abcedf012
    - name: specialProject
      baseUrl: https://special-project-sonarqube.example.com
      apiKey: abcdef0123456789abcedf0123456789ab
