GitHub Actions is an integrated automation platform by GitHub, enabling teams to automate workflows such as code building, testing, and deployment directly from their GitHub repositories, whether they are private or public.

This platform facilitates the connection of various tools to automate each stage of the software development process. It supports the use of pre-built actions or the creation of custom actions to automate common tasks, thereby enhancing code consistency and reliability. The extensive GitHub Actions community and the GitHub Marketplace foster collaboration, knowledge sharing, best practices, and solutions for common challenges.

Key Features of GitHub Actions

GitHub Actions has unique features as listed below:

  • Teams can establish automated workflows to build, test, and deploy code in response to specific events occurring in their GitHub repository, including public repositories and self-hosted runners. Custom environments can be defined for different GitHub Actions workflows.
  • Seamless integration with GitHub’s public or private repositories allows teams to leverage security features, access controls, and code-scanning capabilities.
  • Workflow configurations are defined using YAML files for various GitHub events in the repository, such as pushes to master or pull requests. This allows teams to specify automation steps, conditions, triggers, and other configurations.
  • GitHub Actions provides detailed logs and visual representations of workflows, aiding teams in quickly diagnosing any issues that may arise.
  • Teams can publish artifacts and create releases as part of their workflow, ensuring clear versioning and enabling team members to access and download the correct files at the appropriate time.
  • Workflows can be triggered based on various events within GitHub repositories, such as code pushes, pull requests, or issue creation, initiating automation processes for specific tasks.
  • GitHub Actions supports running tasks on multiple platforms through parallel jobs and matrix builds.
  • As a fully managed service, GitHub Actions operates in the cloud, and there is also an option to run it on a local server for superior flexibility.

GitHub Actions Advantages

Let’s explore the advantages of opting for GitHub Actions over Jenkins now that we have a basic understanding of what it’s all about. 

GitHub Actions is exceptionally user-friendly, requiring just a YAML file to get started. For startups or small businesses, GitHub Actions is a logical choice for a CI/CD platform, especially if your engineers are already familiar with YAML.

In contrast, Jenkins’s workflow is different. It needs to be run on a personal server, which means regular maintenance is necessary.

GitHub Actions Disadvantages

Now, let’s consider the disadvantages of GitHub Actions. When using GitHub Actions, you’re essentially tied to GitHub’s source code management platform. In contrast, Jenkins allows you to keep your code on any repository, including GitLab, Bitbucket, and others.

In terms of maturity and community support, Jenkins has the edge over GitHub Actions. Jenkins is more established and experienced, while GitHub Actions are still in their early stages, resulting in limited community support.

Jenkins

Jenkins is only an open-source Java automation server that is used to automate a process for continually developing, testing, and deploying software projects.

Key Features of Jenkins

Now we are going to take an overview of key features of the Jenkins CI\CD tool:

  • By achieving automation in building and testing the code changes integrated into a shared repository, Jenkins helps to identify the errors easily.
  • Jenkins comes up with diverse testing frameworks and offers automated unit, integration, and regression testing.
  • Jenkins allows the teams to test their tasks across multiple machines to achieve improved efficiency and minimize built times. Schedule builds done at earlier periods or intervals to achieve regular testing and implementation cycles.
  • Jenkins’ scripting language empowers teams to create tailored build and deployment pipelines. The Jenkins server ensures security by offering authentication and authorization choices when integrating with security platforms, ensuring a secure CI/CD workflow. 
  • It seamlessly integrates with version-control systems such as GitHub, enabling automated build, test, and deployment processes triggered by changes to the version-controlled codebase. 
  • Through its dashboard and reporting features, Jenkins offers a comprehensive view of build statuses, test results, and performance metrics.
