SonarQube Plugin

The SonarQube Plugin displays code statistics from SonarCloud or SonarQube.

Getting Started

Install the SonarQube Plugin:

# packages/app

yarn add @backstage/plugin-sonarqube

Add plugin to the app:

// packages/app/src/plugins.ts

export { plugin as SonarQube } from '@backstage/plugin-sonarqube';

Add the SonarQubeCard to the EntityPage:

// packages/app/src/components/catalog/EntityPage.tsx

import { SonarQubeCard } from '@backstage/plugin-sonarqube';

const OverviewContent = ({ entity }: { entity: Entity }) => (
  <Grid container spacing={3} alignItems="stretch">
    // ...
    <Grid item xs={12} sm={6} md={4}>
      <SonarQubeCard entity={entity} />
    </Grid>
    // ...
  </Grid>
);

Add the proxy config:

Provide a method for your Backstage backend to get to your SonarQube API end point.

SonarCloud

# app-config.yaml

proxy:
  '/sonarqube':
    target: https://sonarcloud.io/api
    allowedMethods: ['GET']
    headers:
      Authorization:
        # Content: 'Basic base64("<api-key>:")' <-- note the trailing ':'
        # Example: Basic bXktYXBpLWtleTo=
        $env: SONARQUBE_AUTH_HEADER

SonarQube

# app-config.yaml

proxy:
  '/sonarqube':
    target: https://your.sonarqube.instance.com/api
    allowedMethods: ['GET']
    headers:
      Authorization:
        # Content: 'Basic base64("<api-key>:")' <-- note the trailing ':'
        # Example: Basic bXktYXBpLWtleTo=
        $env: SONARQUBE_AUTH_HEADER

sonarQube:
  baseUrl: https://your.sonarqube.instance.com

Get and provide SONARQUBE_AUTH_HEADER as env variable (https://sonarcloud.io/account/security or https://docs.sonarqube.org/latest/user-guide/user-token/)
