Install SonarQube using Docker | Install SonarQube using Docker on Ubuntu 22.0.4 | Install SonarQube using Docker-Compose

How to setup SonarQube using Docker compose?

SonarQube is static code analysis tool. It is open source and Java based tool. SonarQube can be setup using Docker Compose with less manual steps.

What is Docker Compose?
Compose is a tool for defining and running multi-container Docker applications. With Compose, you use a YAML file to configure your application’s services. Then, with a single command, you create and start all the services from your configuration. Since Docker Compose lets you configure related containers in a single YAML file, you get the same Infrastructure-as-Code abilities as Kubernetes. But they come in a simpler system that’s more suited to smaller applications that don’t need Kubernetes’ resiliency and scaling.
 
The purpose of docker-compose is to function as docker cli but to issue multiple commands much more quickly. To make use of docker-compose, you need to encode the commands you were running before into a docker-compose.yml file
 
Run docker-compose up and Compose starts and runs your entire app.

SonarQube Architecture



SonarQube have three components namely
1. Scanner - This contains scanner and analyser to scan application code.
2. SonarQube server - contains Webserver(UI) and search server 
3. DB server - used for storing the analysis reports.

Watch steps in YouTube channel:


Pre-requisites:

  • New Ubuntu EC2 up and running with at least t2.medium (4 GB RAM)
  • Port 9000 is opened in security firewall rule
  • Make sure below is taken care off.

Login to instance where you will be installing SonarQube, perform the below command to configure virtual memory permanently for SonarQube to function:
sudo vi /etc/sysctl.conf

Add the following lines to the bottom of that file:

vm.max_map_count=262144
fs.file-max=65536

To make sure changes are getting into effect:
sudo sysctl -p

Change Host Name to SonarQube
sudo hostnamectl set-hostname SonarQube

Perform System update
sudo apt update

Install Docker-Compose
sudo apt install docker-compose -y

Create docker-compose.yml
this yml has all configuration for installing both SonarQube and Postgresql:
sudo vi docker-compose.yml 

(Copy the below code high-lighted in yellow color)
version: "3"
services:
  sonarqube:
    image: sonarqube:community
    restart: unless-stopped
    depends_on:
      - db
    environment:
      SONAR_JDBC_URL: jdbc:postgresql://db:5432/sonar
      SONAR_JDBC_USERNAME: sonar
      SONAR_JDBC_PASSWORD: sonar
    volumes:
      - sonarqube_data:/opt/sonarqube/data
      - sonarqube_extensions:/opt/sonarqube/extensions
      - sonarqube_logs:/opt/sonarqube/logs
    ports:
      - "9000:9000"
  db:
    image: postgres:12
    restart: unless-stopped
    environment:
      POSTGRES_USER: sonar
      POSTGRES_PASSWORD: sonar
    volumes:
      - postgresql:/var/lib/postgresql
      - postgresql_data:/var/lib/postgresql/data
volumes:
  sonarqube_data:
  sonarqube_extensions:
  sonarqube_logs:
  postgresql:
  postgresql_data:


Save the file by entering :wq!

Now execute the compose file using Docker compose command:
sudo docker-compose up -d 


Make sure SonarQube is up and running by checking the logs
sudo docker-compose logs --follow


Once you see the message, that's it. SonarQube is been installed successfully. press control C and enter.
Now access sonarQube UI by going to browser and enter public dns name with port 9000

Please follow steps for integrating SonarQube with Jenkins
