dsf azure install sonar with docker in a virtual machine

Connect to a Virtual Machine(VM) in Azure

Pre-requisites

Have a VM created and a private key in order to connect to it

Establish a connection

1- Open the client of your choice(putty,cmder,bash)

2- Ensure you have read-only access to the private key.

chmod 400 azureuser.pem

3- Run this command to connect to your VM

ssh -i <private key path> azureuser@51.103.78.61

note: To get the IP go to your azure portal, click on your VM, click on Networking and you will find the IP needed to establish the connection

You are connected:

Install Sonar using Docker and Docker-compose

As an example we will use the practical case of Bad Weather, a project where we were asked to install Sonar inside a VM in Azure portal

We had 2 possible scenarios, we went for the case A since no other service will be installed in this VM

Steps

1- Install docker and docker compose in the VM

sudo dnf config-manager --add-repo=https://download.docker.com/linux/centos/docker-ce.repo
sudo dnf list docker-ce
sudo dnf install docker-ce --nobest -y
sudo systemctl start docker
sudo systemctl enable docker
docker --version
sudo dnf install curl -y
sudo curl -L "https://github.com/docker/compose/releases/download/1.25.0/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose
sudo ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose
docker-compose --version

2- Deploy SonarQube and Postgress

2.1- Set necesary parameters for sonarqube

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

2.2- Use docker-compose with the next definition to deploy it:

vim /home/sonar/docker-compose.yaml

version: "3"

services:
  sonarqube:
    image: "sonarqube:7.9-community"
    networks:
      - sonar
    environment:
      - sonar.jdbc.username=user
      - sonar.jdbc.password=pass
      - sonar.jdbc.url=jdbc:postgresql://sonarqube-db:5432/sonar
    ports:
      - "80:9000"
	depends_on:
      - "sonarqube-db"
    volumes:
      - "$PWD/volumes/sonarqube/conf:/opt/sonarqube/conf"
      - "$PWD/volumes/sonarqube/data:/opt/sonarqube/data"
      - "$PWD/volumes/sonarqube/extensions:/opt/sonarqube/extensions"
      - "$PWD/volumes/sonarqube/logs:/opt/sonarqube/logs"
    ulimits:
      nofile:
        soft: 65536
        hard: 65536
  sonarqube-db:
    image: "postgres:12-alpine"
    networks:
      - sonar
    volumes:
      - "$PWD/volumes/sonarqube-db/data:/var/lib/postgresql/data"
    environment:
      - POSTGRES_USER=youruser
      - POSTGRES_PASSWORD=yourpass
      - POSTGRES_DB=sonar
      - PGDATA=/var/lib/postgresql/data

networks:
  sonar:
    driver: bridge

3- Update the start configuration to set automatically the correct values and run the docker-compose

vim /usr/local/sbin/start.sh

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

cd /home/sonar && docker-compose up -d

4- Add this to execute the docker-compose file every time the machine turns on

crontab -e
@reboot /usr/local/sbin/start.sh

vim /etc/sysctl.conf
vm.max_map_count=262144
fs.file-max=65536

Your Sonar is Up and running in your VM
