How to setup SonarQube using Docker and Docker compose?

SonarQube is static code analyis tool. It can be installed quickly using Docker with less manual steps.

Pre-requistes:

• Ubuntu EC2 up and running with at least t2.small
  
• Port 9000 is opened in security firewall rule
• Make sure maximum number of 

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

Install Docker

sudo apt-get install docker -y

Install Docker-Compose

sudo apt-get install docker-compose -y

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.

 

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.

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:lts-community

    container_name: sonarqube

    restart: unless-stopped

    environment:

      - SONARQUBE_JDBC_USERNAME=sonar

      - SONARQUBE_JDBC_PASSWORD=password123

      - SONARQUBE_JDBC_URL=jdbc:postgresql://db:5432/sonarqube

    ports:

      - "9000:9000"

      - "9092:9092"

    volumes:

      - sonarqube_conf:/opt/sonarqube/conf

      - sonarqube_data:/opt/sonarqube/data

      - sonarqube_extensions:/opt/sonarqube/extensions

      - sonarqube_bundled-plugins:/opt/sonarqube/lib/bundled-plugins

  db:

    image: postgres:12

    container_name: db

    restart: unless-stopped

    environment:

      - POSTGRES_USER=sonar

      - POSTGRES_PASSWORD=password123

      - POSTGRES_DB=sonarqube

    volumes:

      - sonarqube_db:/var/lib/postgresql10

      - postgresql_data:/var/lib/postgresql10/data

volumes:

  postgresql_data:

  sonarqube_bundled-plugins:

  sonarqube_conf:

  sonarqube_data:

  sonarqube_db:

  sonarqube_extensions:

Save the file by entering :wq!

Now execute the compose file using Docker compose command:

sudo docker-compose up -d 

If you are getting any errors like this, make sure you exit below commands to adding Docker group to current user.

sudo usermod -aG docker $USER

Make sure SonarQube is up and running

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

Now to go to browser --> http://your_SonarQube_publicdns_name:9000/
