SonarQube

The SonarQube integration plugin for Soundcheck supports the extraction of the following facts:

Prerequisites​

Configure SonarQube integration in Backstage​

Integrations are configured at the root level of app-config.yaml. Here's an example configuration for SonarQube:

soundcheck:
  collectors:
    sonarqube:
      token: Token

      # Alternatively you may use username and password
      # username:
      # password:

      # If you wish to override the api URL
      # baseUrl: https://sonarqube.com

Additionally, you can use multiple instances of SonarQube. When using multiple instances, the instance is determined by the sonarqube.org/project-key annotation from the entity's metadata configuration.

soundcheck:
  collectors:
    sonarqube:
      - name: instance1
        baseUrl: http://sonarqube-instance1.example.com  # Is not required to be different for each instance
        token: Token
      - name: instance2
        baseUrl: http://sonarqube-instance2.example.com  # Is not required to be different for each instance
        token: Token

Add the SonarQubeFactCollector to Soundcheck​

First, add the package:

yarn workspace backend add @spotify/backstage-plugin-soundcheck-backend-module-sonarqube

Legacy Backend​

If you are still using the legacy backend, in packages/backend/src/plugins/soundcheck.ts, add the SonarQubeFactCollector:

import { SoundcheckBuilder } from '@spotify/backstage-plugin-soundcheck-backend';
import { Router } from 'express';
import { PluginEnvironment } from '../types';
+ import { SonarQubeFactCollector } from '@spotify/backstage-plugin-soundcheck-backend-module-sonarqube';

export default async function createPlugin(
  env: PluginEnvironment,
): Promise<Router> {
  return SoundcheckBuilder.create({ ...env })
    .addFactCollectors(
+      SonarQubeFactCollector.create(env.logger)
    )
    .build();
}

Consult the Soundcheck Backend documentation for additional details on setting up the Soundcheck backend.

New Backend System​

If you are using the New Backend System, you can just add the following:

packages/backend/src/index.ts
const backend = createBackend();

backend.add(import('@spotify/backstage-plugin-soundcheck-backend'));
backend.add(import('@spotify/backstage-plugin-soundcheck-backend-module-sonarqube'));
// ...

backend.start();

Plugin Configuration​

The collection of SonarQube facts is driven by configuration. To learn more about the configuration, consult the Defining SonarQube Fact Collectors section.

  1. Create a sonarqube-facts-collectors.yaml file in the root of your Backstage repository and fill in all your SonarQube Fact Collectors. A simple example SonarQube fact collector is listed below.

    ---
    token: dummy
    collects:
      - type: projects
        filter:
          - spec.lifecycle: 'production'
            spec.type: 'website'
        cache: false

    Note: this file will be loaded at runtime along with the rest of your Backstage configuration files, so make sure it's available in deployed environments in the same way as your app-config.yaml files.

  2. Add a Soundcheck collectors field to the app-config.yaml and reference the newly created sonarqube-facts-collectors.yaml file.

    # app-config.yaml
    soundcheck:
      collectors:
        sonarqube:
          $include: ./sonarqube-facts-collectors.yaml

    # You can also utilize multiple instances with the Soundcheck collectors:
    # soundcheck:
    #   collectors:
    #     sonarqube:
    #       - $include: ./sonarqube-facts-collectors-instance1.yaml
    #       - $include: ./sonarqube-facts-collectors-instance2.yaml

Rate Limiting (Optional)​

This fact collector can be rate limited in Soundcheck using the following configuration:

soundcheck:
  job:
    workers:
      sonarqube:
        limiter:
          max: 1000
          duration: 60000

In this example, the fact collector is limited to 1000 executions per minute.

This fact collector handles 429 rate limit errors from SonarQube. Soundcheck will automatically wait and retry requests that are rate limited.

Defining SonarQube Fact Collectors​

This section describes the data shape and semantics of SonarQube Fact Collectors.

Overall Shape Of A SonarQube Fact Collector​

The following is an example of a descriptor file for a SonarQube Fact Collector:

---
baseUrl: https://sonarqube.com
token: dummy
collects:
  - type: project
    filter:
      - spec.lifecycle: 'production'
        spec.type: 'website'
    cache: false

Below are the details for each field.

name [optional]​

The unique identifier used by the plugin to determine the instance needed to collect facts based on the sonarqube.org/project-key annotation value in an entity's metadata configuration. If this value is not provided, a default value of sonarqube will be used. Additionally, if the instance names are not unique then the last entry will be the one used to collect the facts about an entity.

baseUrl [optional]​

The base URL of the SonarQube instance to use. If not provided, the plugin will attempt to use the default URL https://sonarqube.com.

token [optional]​

The SonarQube token to use for authentication. If not provided, the plugin will attempt to use username and password instead.

username [optional]​

The SonarQube username to use for authentication. If not provided, the plugin will attempt to use token instead.

password [optional]​

The SonarQube password to use for authentication. If not provided, the plugin will attempt to use token instead.

collects [required]​

An array describing which facts to collect and how to extract them. See below for details about the overall shape of a fact extractor.

Overall Shape Of A Fact Extractor​

Each extractor supports the fields described below.

type [required]​

The type of the extractor (e.g. projects, project-tags, issues).

frequency [optional]​

The frequency at which the fact extraction should be executed. Possible values are either a cron expression { cron: ... } or HumanDuration. If provided, it overrides the default frequency provided at the top level. If not provided, it defaults to the frequency provided at the top level. If neither extractor's frequency, nor default frequency is provided, the fact will only be collected on demand. Example:

frequency:
  minutes: 10

initialDelay [optional]​

The amount of time that should pass before the first invocation happens. Possible values are either a cron expression { cron: ... } or HumanDuration.

Example:

initialDelay:
  seconds: 30

filter [optional]​

A filter specifying which entities to collect the specified facts for. Matches the filter format used by the Catalog API. If provided, it overrides the default filter provided at the top level. If not provided, it defaults to the filter provided at the top level. If neither extractor's filter nor default filter is provided, the fact will be collected for all entities.

cache [optional]​

If the collected facts should be cached, and if so for how long. Possible values are either true or false or a nested { duration: HumanDuration } field. If provided it, overrides the default cache config provided at the top level. If not provided, it defaults to the cache config provided at the top level. If neither extractor's cache nor default cache config is provided, the fact will not be cached. Example:

cache:
  duration:
    hours: 24

Entity configuration​

In your catalog-info.yaml file, add the following metadata annotation to allow the plugin to map an entity to a project in SonarQube.

metadata:
  annotations:
    sonarqube.org/project-key: test-project-key

Collecting Projects Fact​

Collecting Measures Fact​

A measures fact contains information about measures from SonarQube Measures API.

Shape of A Measures Fact Collector​

The shape of a Measures Fact Collector matches the Overall Shape Of A SonarQube Fact Collector ( restriction: type: measures).

The following is an example of the Measures Fact Collector config:

- type: measures
  cache: true
  frequency:
    cron: '0 * * * *'

Configure metric keys​

A Measures fact can be configured to which metrics should be fetched. By default, it will fetch the following metric keys:

  • ncloc
  • complexity
  • violations
  • open_issues

To configure it, add following section in your YAML configuration. Note the metrics will completely override the default ones, so you need to include them if you wish to fetch them as well.

soundcheck:
  collectors:
    sonarqube:
      collects:
        - factName: extendedMeasures
          type: measures
          metrics:
            - ncloc
            - complexity
            - violations
            - open_issues
            - bugs
            - code_smells

You can see a full list of available metrics in your instance with the following HTTP request:
