SonarQube with pre commit hook ⚓

In this blog i’ll explain how to configure SonarQube to check for code quality by adding it to pre commit hook, so lets get started …

Point of adding sonarQube as pre commit hook is to let developers in teams check their code quality before pushing it to version control system (popular one: git)

There are just 3 simple steps to get it configured

There are 2 ways to install, first one via docker and other by installing zip file

First approach- Docker (

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

This command will install docker image and run it if not present locally to check if it ran successfully run below command and under image tab in one of your images you’ll see sonarqube,

(make sure you have docker installed on your machine)

docker ps

then open the browser hit localhost:9000 you will see homepage of sonarqube . To login just hit

username - admin and password- admin

Second Approach- By downloading sonarqube from official website and installing it, there is awesome blog on how to configure that, follow it and you will be able to install sonarQube

Install sonar scanner for official website

open your .git folder (generally hidden)

on linux machine hit ctrl H

on windows follow this

after opening .git folder open hooks and inside that folder create a file with name pre-commit and paste content specified below

#!/bin/bashchmod +x .git/hooks/pre-commitexport PATH="$PATH:YOUR_PATH_TO_SONAR_SCANNER_BIN"sonar-scanner -Dsonar.projectKey=YOUR_PROJECT_NAME -Dsonar.sources=. -Dsonar.host.url=http://localhost:9000 -Dsonar.qualitygate.wait=true

export command will work only in linux machine use set for windows

change YOUR_PROJECT_NAME to your project name

change YOUR_PATH_TO_SONAR_SCANNER_BIN with the path of bin that you have downloaded earlier in step 2, sample on linux machine would be

export PATH="$PATH:/home/mypc/Downloads/sonar-scanner-cli-4.2.0.1873-linux/sonar-scanner-4.2.0.1873-linux/bin"

After all these step you should be able to use pre commit hook on your git(vcs) repository, check by commiting any files on git.

We must use some kind of tool to check our code quality either by sonarQube or by any other tool out there like flake8, pylint (for python)
