How to use this image

This Docker image contains the Community Edition of SonarQube.

Run SonarQube

The server is started this way:

$ docker run -d --name sonarqube -p 9000:9000 %%IMAGE%%

By default you can login as admin with password admin, see authentication documentation.

To analyze a Maven project:

# On Linux:
mvn sonar:sonar

# With boot2docker:
mvn sonar:sonar -Dsonar.host.url=http://$(boot2docker ip):9000

To analyze other kinds of projects and for more details see Analyzing Source Code documentation.

Advanced configuration

Option 1: Database configuration

By default, the image will use an embedded H2 database that is not suited for production.

The production database is configured with the following SonarQube properties used as environment variables: sonar.jdbc.username, sonar.jdbc.password and sonar.jdbc.url.

$ docker run -d --name sonarqube \
    -p 9000:9000 \
    -e sonar.jdbc.username=sonar \
    -e sonar.jdbc.password=sonar \
    -e sonar.jdbc.url=jdbc:postgresql://localhost/sonar \
    sonarqube

Use of the environment variables SONARQUBE_JDBC_USERNAME, SONARQUBE_JDBC_PASSWORD and SONARQUBE_JDBC_URL is deprecated, and will stop working in future releases.

More recipes can be found here.

Option 2: Use parameters via Docker environment variables

You can pass sonar. configuration properties as Docker environment variables, as demonstrated in the example above for database configuration.

Option 3: Use bind-mounted persistent volumes

The images contain the SonarQube installation at /opt/sonarqube. You can use bind-mounted persistent volumes to override selected files or directories, for example:

sonarqube_conf:/opt/sonarqube/conf: configuration files, such as sonar.properties
sonarqube_data:/opt/sonarqube/data: data files, such as the embedded H2 database and Elasticsearch indexes
sonarqube_logs:/opt/sonarqube/logs
sonarqube_extensions:/opt/sonarqube/extensions: plugins, such as language analyzers

You could also use bind-mounted configurations specified on the command line, for example:

$ docker run -d --name sonarqube \
    -p 9000:9000 \
    -v /path/to/conf:/opt/sonarqube/conf \
    -v /path/to/data:/opt/sonarqube/data \
    -v /path/to/logs:/opt/sonarqube/logs \
    -v /path/to/extensions:/opt/sonarqube/extensions \
    sonarqube

Option 4: Customized image

In some environments, it may make more sense to prepare a custom image containing your configuration. A Dockerfile to achieve this may be as simple as:

FROM sonarqube:7.4-community
COPY sonar.properties /opt/sonarqube/conf/

You could then build and try the image with something like:

$ docker build --tag=sonarqube-custom .
$ docker run -ti sonarqube-custom
