Automating SonarQube Report Management

Overseeing the code quality of several microservices can be a difficult undertaking. This approach can be greatly streamlined by automating the download, storage, and commit of SonarQube results to a Git repository.

This tutorial will show you how to write a bash script that downloads 30 microservices' worth of SonarQube reports, puts them in a specified directory on a Linux server, and commits them to a Git repository. You will also learn the command to see these reports on your server by the end.

Command	Description
mkdir -p	If a directory doesn't already exist, creates it.
curl -u	Executes an HTTP request with authentication in order to download files from a server.
os.makedirs	Recursively creates a directory in Python if it doesn't already exist.
subprocess.run	Executes a Python command with arguments and then waits for it to finish.
cp	Transfers folders or files between locations.
git pull	Pulls updates from a remote Git repository and merges them into the active branch.
git add	Updates the staging area with file modifications from the working directory.
git commit -m	Adds modifications to the repository along with a note outlining the alterations.
git push	Transfers content from a local repository to a distant repository.
requests.get	Sends a Python GET request to the given URL.

Automating SonarQube Report Management

These scripts are made to automate the steps of receiving SonarQube reports for several microservices, saving them to a Linux server's designated directory, and committing the reports to a Git repository. To begin, the bash script defines the required variables, including the path to the Git repository, the SonarQube server URL, the token, the list of microservices, and the resource directory. If the resource directory does not already exist, it is then created using mkdir -p. The script iterates over every microservice, creates the report URL, downloads the report using curl -u, and stores it in the resource directory as a JSON file.

The script downloads the reports, modifies the directory of the Git repository, copies the reports into the Git repository, and runs a git pull to make sure it contains the most recent changes. After that, it uses git add to stage the changes, git commit -m to commit them with a message, and git push to push the changes to the remote repository. A similar set of activities are carried out by the Python script, which makes use of the os.makedirs function for creating folders, the requests.get function for downloading reports, and the subprocess.run function for running Git commands. SonarQube reports are methodically managed and stored thanks to this configuration.

Getting SonarQube Reports for Microservices and Saving Them

An Automated Bash Script for SonarQube Report Management

#!/bin/bash
# Define variables
SONARQUBE_URL="http://your-sonarqube-server"
SONARQUBE_TOKEN="your-sonarqube-token"
MICROSERVICES=("service1" "service2" "service3" ... "service30")
RESOURCE_DIR="/root/resource"
GIT_REPO="/path/to/your/git/repo"

# Create resource directory if not exists
mkdir -p $RESOURCE_DIR

# Loop through microservices and download reports
for SERVICE in "${MICROSERVICES[@]}"; do
    REPORT_URL="$SONARQUBE_URL/api/measures/component?component=$SERVICE&metricKeys=coverage"
    curl -u $SONARQUBE_TOKEN: $REPORT_URL -o $RESOURCE_DIR/$SERVICE-report.json
done

# Change to git repository
cd $GIT_REPO
git pull

# Copy reports to git repository
cp $RESOURCE_DIR/*.json $GIT_REPO/resource/

# Commit and push reports to git repository
git add resource/*.json
git commit -m "Add SonarQube reports for microservices"
git push

# Command to display report in Linux server
cat $RESOURCE_DIR/service1-report.json

Automating Git Tasks for Reports in SonarQube

Python Script for Git Report Management with SonarQube

import os
import subprocess
import requests

# Define variables
sonarqube_url = "http://your-sonarqube-server"
sonarqube_token = "your-sonarqube-token"
microservices = ["service1", "service2", "service3", ..., "service30"]
resource_dir = "/root/resource"
git_repo = "/path/to/your/git/repo"

# Create resource directory if not exists
os.makedirs(resource_dir, exist_ok=True)

# Download reports
for service in microservices:
    report_url = f"{sonarqube_url}/api/measures/component?component={service}&metricKeys=coverage"
    response = requests.get(report_url, auth=(sonarqube_token, ''))
    with open(f"{resource_dir}/{service}-report.json", "w") as f:
        f.write(response.text)

# Git operations
subprocess.run(["git", "pull"], cwd=git_repo)
subprocess.run(["cp", f"{resource_dir}/*.json", f"{git_repo}/resource/"], shell=True)
subprocess.run(["git", "add", "resource/*.json"], cwd=git_repo)
subprocess.run(["git", "commit", "-m", "Add SonarQube reports for microservices"], cwd=git_repo)
subprocess.run(["git", "push"], cwd=git_repo)

# Command to display report
print(open(f"{resource_dir}/service1-report.json").read())

Boosting Automation via Cron Employment

Cron tasks can be used to further automate the download and commit of SonarQube findings. In Unix-like operating systems, cron jobs are scheduled tasks that execute at predetermined intervals. You can program the scripts to run regularly at regular intervals, like weekly or daily, by setting up a cron job. This will guarantee that your SonarQube reports are updated automatically and without the need for human interaction. The crontab -e command can be used to change the cron table and add an item that specifies the script and its schedule, which will establish a cron job.

This method lowers the possibility of missing report updates and guarantees total automation of the process. Log files can also be used to monitor the success or failure of cron job executions. You can generate an exhaustive log of all actions by include logging commands, like echo "Log message" >> /path/to/logfile, in your script. With this configuration, you may easily and dependable maintain your microservices' continuous integration and delivery (CI/CD) pipelines.
