Jenkins and Sonar on Docker for PHP

INSTALL JENKINS IMAGE FOR DOCKER
--------------------------------

Go as root:

$ sudo su

Run the jenkins container for the first time specifying the volume on current filesystem and ports:

# docker run -p 8080:8080 -p 50000:50000 -v /home/phackwer/Projects/jenkins/:/var/jenkins_home jenkins

Write down the admin password (or copy annd paste), you will need it to setup jenkins. 
Go to http://localhost:8080 and install the required plugins for the PHP analisys and deployment.

Check the Container ID running the command

# docker ps

CONTAINER ID        IMAGE                     COMMAND                  CREATED              STATUS              PORTS                                              NAMES
d0db6f994cc7        jenkins                   "/bin/tini -- /usr/lo"   About a minute ago   Up About a minute   0.0.0.0:8080->8080/tcp, 0.0.0.0:50000->50000/tcp   elegant_northcutt
8189df2752ab        sonarqube                 "./bin/run.sh"           5 hours ago          Up 5 hours          0.0.0.0:9000->9000/tcp, 0.0.0.0:9092->9092/tcp     sonarqube

The Container ID in this case is d0db6f994cc7. We will use it from now on for a lot of operations.

You can get any docker container informations (IPs, etc) running the command:

# docker inspect 4890c0554b8

SETUP JENKINS FOR PHP
---------------------

Login as root on a running docker container:

# docker exec -u 0 -i -t d0db6f994cc7 /bin/bash

On the container, install required ubuntu packages:

# apt-get install -y software-properties-common python-software-properties

Add PHP 7.0 support:

# echo '' >>  /etc/apt/sources.list 
# echo 'deb http://packages.dotdeb.org jessie all' >> /etc/apt/sources.list 
# echo 'deb-src http://packages.dotdeb.org jessie all' >> /etc/apt/sources.list 
# apt-get update
# apt-get install -y --force-yes imagemagick libmagickwand-dev libpcre3 libpcre3-dev \
  php7.0 php7.0-mcrypt php7.0-mbstring php7.0-dev php7.0-mysql php7.0-odbc \
  php7.0-json php7.0-bcmath php7.0-fpm php7.0-gd php7.0-intl \
  php7.0-pgsql php7.0-curl php7.0-gd php7.0-sqlite3 php7.0-xml
  
Add Composer support so you can build your installation package:

# wget https://getcomposer.org/installer
# php installer
# mv composer.phar /usr/bin/composer


INSTALL SONARQUBE IMAGE FOR DOCKER
----------------------------------

As root, run

# docker run -d --name sonarqube -p 9000:9000 -p 9092:9092 sonarqube

Now login as admin with admin password on http://localhost:9000 and just add the plugin to support the PHP language.

SETUP JENKINS TO USE SONAR
--------------------------

Use the following commands to get the SonarQube IP Address:

# docker ps

CONTAINER ID        IMAGE                     COMMAND                  CREATED              STATUS              PORTS                                              NAMES
d0db6f994cc7        jenkins                   "/bin/tini -- /usr/lo"   About a minute ago   Up About a minute   0.0.0.0:8080->8080/tcp, 0.0.0.0:50000->50000/tcp   elegant_northcutt
8189df2752ab        sonarqube                 "./bin/run.sh"           5 hours ago          Up 5 hours          0.0.0.0:9000->9000/tcp, 0.0.0.0:9092->9092/tcp     sonarqube

# docker inspect 8189df2752ab | grep "IPAddress"

Go to the Configure System and add a SonarQube Server pointing to the address you got from the previous command.
Just to be fast, we will say we are using the 5.2 version and inform admin/admin username/password combination.

Now  go to Global Tool Configuration and find the SonarQube Scanner section.
Click the SonarQube Scanner Instalations and add one.
Select the Install Autoomatically option.
