Dockerfile to build a SonarQube container image.

Current Version: 5.6

Before you start, you need to make sure you have the following dependencies installed:

• Install Docker
• Install Docker Compose

Now you can verify that the installation is ok with the following commands:

docker version
docker-compose --version

If you have any issues you can report them on the issues page.

In your report please make sure to add:

• Output of the docker version command
• The exact docker run or docker-compose command you used (mask any sensitive info)

Pull the image from the docker index. This is the recommended method of installation as it is easier to update image in the future. These builds are performed by the Trusted Build service.

docker pull harbur/sonarqube:latest

The image builds are being tagged. You can pull a particular version of SonarQube by specifying the version number. For example,

docker pull harbur/sonarqube:5.6

Alternately you can build the image yourself if you run 5.6.

git clone https://github.com/harbur/docker-sonarqube.git
cd docker-sonarqube
docker build --tag="$USER/sonarqube" .

Run the SonarQube with Docker Compose. Docker Compose uses a docker-compose.yml file that describes the environment.

git clone https://github.com/harbur/docker-sonarqube.git
cd docker-sonarqube
docker-compose up

NOTE: It will build Sonar 5.6 container. If you want to run pre build 5.1, please edit the docker-compose.yml accordingly.

NOTE: Please allow a minute or two for the SonarQube application to start.

On another console run:

make port

Point your browser to the given URL and login using the default username and password:

• username: admin
• password: admin

You should now have the SonarQube application up and ready for testing. If you want to use this image in production the please read on.

SonarQube uses PostgreSQL database backend to store its data. Database is launched as separate container and the linking is handled by Docker Compose.

The DB container is configured to create automatically the user and the database. The user credentials, database name and the database hostname are all injected to the SonarQube container by docker-compose using environment variables and container links.

The SonarQube container does not contain database by itself, there is no simple-container scenario. It needs to run with docker-compose commands (or you can craft manually the docker commands). This makes it a lot more portable, and follows the Single Responsibility Principle and aligns well with the Service-oriented Architecture design pattern. This works seamlessly in the simple-host / multi-container scenario. The multi-host / multi-container scenario is explained later on.

The database used is orchardup/postgresql and uses a Volume to store the database (/var/lib/postgresql) separately from the container instance.

The Postgresql database container is configured to persist data inside a Volume: /var/lib/postgresql.

If you want to mount the volume locally, you can append the following lines at the docker-compose.yml inside the postgres section:

NOTE: If you mount the volume locally, you'll singularize your setup, making all instances point to the same directory, safe if you want only one SonarQube instance.

  volumes:
    - /opt/db/sonarqube/:/var/lib/postgresql

In order to connect to the database you can do the following:

docker-compose up -d postgresql
docker-compose run postgresql bash -c 'PGPASSWORD=$POSTGRESQL_PASS psql -h $POSTGRESQL_1_PORT_5432_TCP_ADDR $POSTGRESQL_DB $POSTGRESQL_USER'

This will launch the database of PostgreSQL (first command) and then connect to the database with a client (second command). The containers are linked together automatically by docker-compose and the variables are used to pass the connection info.

For debugging and maintenance purposes you may want access the container shell. Since the container does not include a SSH server, you can use the nsenter linux tool (part of the util-linux package) to access the container shell.

Some linux distros (e.g. ubuntu) use older versions of the util-linux which do not include the nsenter tool. To get around this @jpetazzo has created a nice docker image that allows you to install the nsenter utility and a helper script named docker-enter on these distros.

To install the nsenter tool on your host execute the following command.

docker run --rm -v /usr/local/bin:/target jpetazzo/nsenter

Now you can access the container shells using the following commands

sudo docker-enter dockersonarqube_sonarqube_1
sudo docker-enter dockersonarqube_postgresql_1

Another tool named nsinit can also be used for the same purpose. Please refer https://jpetazzo.github.io/2014/03/23/lxc-attach-nsinit-nsenter-docker-0-9/ for more information.
