Introduction

Dockerfile to build a SonarQube container image.

Version

Current Version: 5.0

Dependencies

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

• Install Docker
• Install Fig

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

docker version
fig --version

Reporting Issues

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 fig command you used (mask any sensitive info)

Installation

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:4.4

Alternately you can build the image yourself.

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

Quick Start

Run the SonarQube with Fig. Fig uses a fig.yml file that describes the environment.

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

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.

Configuration

Database

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

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 fig 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 fig 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.

Data Store

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 fig.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

Connect with a PostgreSQL client

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

fig up -d postgresql
fig 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 fig and the variables are used to pass the connection info.

Shell Access

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

For more information refer https://github.com/jpetazzo/nsenter

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.
