CI/CD with Jenkins – Part 3: Install and Configure SonarQube

What is SonarQube

SonarQube formerly known as Sonar, is an open source tool suit to measure and analyze to quality of source code. It is written by Java but is able to analyze code in 20 different programming languages. With SonarQube, developers can easily to check to ensure quality, reliability and maintainability over life-span of the project.

In this part 3, we are going to install SonarQube with Docker. This is just for testing and demostrating.

Install docker

Remove old docker and docker components

sudo yum remove docker docker-common docker-selinux docker-engine

Install dependency

sudo yum install -y yum-utils device-mapper-persistent-data lvm2

Add Third Party Docker Repo
I have a bad network connection with Docker Official Repo, so I choose the third party repo, which is faster than Docker’s one.

wget -O /etc/yum.repos.d/docker-ce.repo

For Docker Official Repo, Please use the following

sudo yum-config-manager \
    --add-repo \

update yum index and install docker

sudo yum makecache fast
sudo yum install docker-ce

enable and start docker

[root@jenkins ~]# systemctl enable docker
[root@jenkins ~]# systemctl start docker

Pull SonarQube image from docker

[root@jenkins ~]# docker pull sonarqube

I set recommend values for current session by using following commands as root on the host

sysctl -w vm.max_map_count=262144
sysctl -w fs.file-max=65536
ulimit -n 65536
ulimit -u 4096

Run SonarQube

[root@jenkins ~]# docker run -d --name sq -p 9000:9000 sonarqube

if SonarQube instance is killed by docker after a while, it is best to configure a timeout to stop the container with –stop-timeout

[root@jenkins ~]# docker run -d --stop-timeout 3600 sonarqube --name sq -p 9000:9000  sonarqube

After SonarQube installed, access to login and configure.
The default username and password is admin/admin

Once login, SonarQube will ask you to provide a token name and generate a token.

Keep this Token, we will add it into Jenkins crentials.

Integrate Sonar with Jenkins

Install SonarQube Plugins in Jenkins.

Navigate to Manage Jenkins->Manage Plugins

Configure SonarQube servers in Jenkins

Navigate to Manage Jenkins->Configure System->SonarQube servers,

Go to Manage Jenkins->Global Tool Configuration

In this post, we have learned to install SonarQube with Docker and configure Sonar settings in Jenkins. we have generated a Token of SonarQube that will be used to authorize to login SonarQube.
