What is SonarQube
SonarQube is an open-source platform that provides continuous code quality inspection and performs automatic reviews. It highlights bugs, detects security vulnerabilities, and identifies code smells in over 20 programming languages.
SonarQube and Code Quality
SonarQube offers a holistic and detailed view of your application's health status. It points out what components of your code need to be fixed and offers suggestions for improvement to make your code more secure and efficient. Consequently, with SonarQube, you can see where the problems are exactly and how to fix them.
Additionally, SonarQube not only flags the issues after scanning the code but also prioritizes the issues based on their impact and ease of correction. This aspect makes SonarQube an effective code quality tool to help you or your teams plan the time and effort needed to maintain code quality effectively.
SonarQube Installation Overview
SonarQube installation is a relatively straightforward process, although the steps involved may vary depending on your Operating System(OS) and Development environment. But, before we dive deeper into how to install Sonarqube, it's worth noting that this code quality tool offers three different editions, each tailored to different development needs:
- Community Edition: This is SonarQube’s free version, which provides the basic capabilities for code quality management. It is ideal for small teams or individual developers who are just getting started with SonarQube.
- Developer Edition: This version offers more advanced features, including branch analysis and integration with popular IDEs. It is designed for professional Development teams seeking enhanced code quality management features.
- Enterprise Edition: As the most feature-rich version, the Enterprise Edition provides features like security reports, portfolio management, and support for large Development teams. This edition is geared towards large organizations with extensive codebases and advanced code quality control needs.
In addition to the Community, Developer, and Enterprise editions, SonarQube also offers a Cloud-based version known as SonarCloud. SonarCloud provides the convenience and flexibility of a Cloud-based solution, eliminating the need for any type of installation or server maintenance.
Essentially, SonarCloud is designed specifically for teams and organizations that are leveraging Cloud technologies and are interested in a 'Software-as-a-Service' (SaaS) model. It offers automated code review and quality testing capabilities, similar to its on-premise counterparts.
However, its distinct advantage lies in the fact that it allows Developers to focus on their code, while the platform takes care of running the analyses and maintaining the service.
Therefore, for teams looking for an efficient, scalable, and maintenance-free tool to maintain their code quality, SonarCloud presents an excellent option.
To try it out, use this Sonarqube installation guide available on their official website.
What is GitHub Actions?
GitHub Actions is a robust CI/CD solution that enables Developers to automate their software development workflows. This includes everything from performing routine tasks like code compilation and Unit Testing, all the way to deploying applications onto production servers. This is crucial, especially, in the rapidly changing landscape of Software Development, where automation and efficient workflows have become paramount.
The ability to automate these tasks can result in significant time and resource savings, allowing teams to focus on the core Development work rather than getting bogged down in routine processes.
Nonetheless, the versatility of GitHub Actions extends beyond just CI/CD. It offers a flexible platform where workflows can be tailored to any event that occurs within a GitHub repository, such as pull requests or issue comments. This makes it an extremely powerful tool for automating a wide range of tasks, extending to not only software builds and tests, but also Project Management and coordination activities.
Moreover, with GitHub Actions, you can build and test your applications across multiple platforms and languages. This cross-platform support ensures that applications work seamlessly across different Operating Systems and environments.
How to Install and Run SonarQube and GitHub Actions to Optimize Code Quality
SonarQube Installation Guide
The installation process for each of the SonarQube editions we mentioned above is similar, with the main difference being the licensing requirements for the Developer and Enterprise editions. For this guide, we used Sonar Community in a Docker container.
In this example, we used a server on AWS EC2 with Docker engine installed, with 2vcpu and 4GB of RAM, and 8GB of disk. However, you can use a provider with free credits, for example:
https://try.digitalocean.com/freetrialoffer/
Follow Docker-Compose to facilitate your study lab:
Now, execute:
In a few seconds, try to access your public IP, remember that this compose is configured on port 9000 to access the SonarQube console, but you can change it if you need. If everything worked well, you’ll see this screen:
Here, the default access is admin/admin:
As good practice, the platform requires you to update your password;
Performing Static Code Analysis
With SonarQube installed and set up, the next step is to perform static code analysis. This analysis allows you to identify code quality and security problems. By default, SonarQube has pre-configured check rules already, which speeds up your work significantly. However, you can change them if the need arises.
In this case, we are working with Python, so we look at Python rules;
It is possible to create your own check profiles, or even your quality gates with custom rules 100% tailored for your scenario.
Below is an image of the results of once the analysis is complete;
Integrating SonarQube with GitHub Actions
Integrating SonarQube with GitHub Actions facilitates the execution of automatic code analysis at each push or pull request. This helps you to ensure code quality throughout the software life cycle. See how to do this below:
Step 1; As there is no project, the platform presents you with a quick way to get started. Select to start "Manually":
Step 2; Let's use the TODO app for this example;
It is very important to define the branch in which you are working.
Step 3; Next, let's follow this first moment with the global configuration, because it's just an example, but you can choose models of checks.
Step 4; Now, go to the integration with Github Actions by simply clicking on the box labeled “GitHub Actions.”
Important information for integration will be provided, such as the creation of Secrets for this connection. Note that the creation of the access token to SonarQube will be required as well.
Step 6; Continuing with the integration, you’ll need to pick the language you’ll check. In In this example we use Python, so we chose the last option.
When choosing the programming language, the platform shows the steps to be configured in GitHub Actions. It is necessary to add a file in the root of the project under the name "sonar-project-properties."
Setting up Github Actions for Code Quality Maintenance
Creating a workflow
With GitHub Actions set up, now we can create our first workflow. But where do you start?
Like SonarQube, GitHub Actions also requires an initial setup. This setup may vary depending on your project's needs.
Browse to your repo and fork it.
Go to the “Settings” menu;
Now, we will create SONAR_TOKEN and SONAR_HOST_URL
After creating the secrets, go to the Actions Menu;
Copy and paste the script of SonarQube’s suggestion;
Choose the name of your workflow and commit changes;
Congratulations if you made it this far because we were able to integrate SonarQube with GitHub Actions.
However, we are not done yet.
