Introduction to Github Actions

Github is a continuous Integration and Continous delivery platform that provides an excellent option for automating workflows to run specific tasks when some event like code push or a release is triggered on the repository. In this Session we will be exploring Github Actions and learning how to use them in our projects.
![Workflows support a number of different automations ranging from pull requests and branch
merging—plus, third-party integrations with your 5 preferred tools such as chat app
notifications, testing suites, container management, and more via the GitHub Marketplace.
You can leverage automated workflows to build, test, and deploy code directly into a virtual
machine or a Docker container. GitHub Actions also supports “matrix builds,” which enables
you to simultaneously test builds across multiple operating systems and runtime versions.

KnolX Etiquettes Punctuality Respect Knolx session timings, you are requested not to join sessions after a 5 minutes threshold post the session start time. Feedback Make sure to submit a constructive feedback for all sessions as it is very helpful for the presenter. Silent Mode Keep your mobile devices in silent mode, feel free to move out of session in case you need to attend an urgent call. Avoid Disturbance Avoid unwanted chit chat during the session.

- 4. What is GitHub Actions? GitHub Actions gives developers the ability to automate their workflows across issues, pull requests, and more—plus native CI/CD functionality. It was launched in 2018 as to help developers automate their workflows—all within GitHub.
- 5. GitHub Actions allows users on GitHub to perform a large number of actions, such as deploy to AWS, Terraform, Email the developers if a commit breaks any tests, and much, much more! At the most basic level, GitHub Actions brings automation directly into the software development lifecycle on GitHub via event-driven triggers. These triggers are specified events that can range from creating a pull request to Pushing
- 6. All GitHub Actions automations are handled via workflows, which are YAML files placed under the .github/workflows directory in a repository that define automated processes. Workflows
- 7. Every workflow consists of several different core concepts. These include: Events: Events are defined triggers that kick off a workflow. They can be configured to look for one or more triggers and qualified as 4 needed by a developer. They can also be set to run on specific branches within a given repository on GitHub. Jobs: Jobs are a set of steps that execute on the same runner. Each runs in its own VM and parallel to other jobs, unless otherwise specified. Steps: Steps are individual tasks that run commands in a job. These can be an action or a shell command. All steps in a job execute on the same runner. Actions: An action is a command that’s executed on a runner—and the core element of GitHub Actions, which is named after it. Runners: A runner is a GitHub Actions server. It listens for available jobs, runs each in parallel, and reports back progress, logs and results. Each runner can be hosted by GitHub or self-hosted on a localized server. GitHub Hosted runners are based on Ubuntu Linux, Windows, and macOS.

- 9. Workflows Events Pull/Push/Fork/issues Jobs Steps Note: one event can trigger many workflows, a workflow can contain many jobs, and a job can contain many steps.
- 10. Why having a GitHub-native CI/CD tool is helpful: The most basic answer is simplicity—if you’re already hosting a project on GitHub, you have a built-in CI/CD tool that works right alongside your code. Github Actions is fully integrated into Github and therefore doesn't require and external site. This means that it can be managed in the same place where your source Code is Present. It allows you to test your code in different operating systems as well as on container. Github provides multiple templates for all kinds of CI as well as it also allows you to create your own templates. Actions are completely free for every open-source repository and include 2000 free build minutes per month for all your private repositories which is comparable with most CI/CD free plans.
- 11. Use Cases of Github Actions Some of the of the most common use cases for GitHub Actions include: 1. Build, test, and deploy within the GitHub flow 2. Automate repetitive tasks: GitHub Actions can be used to automate an almost endless number of steps in the software development lifecycle. Whether it’s the creation of a pull request, a new contributor joining your repository 3. Easily add preferred tools and services to your project: GitHub Actions gives you the ability to connect and integrate your preferred third-party tools and services directly into your repository. 4. Keep track of your projects: You can use GitHub Actions to monitor application builds, measure performance, track errors and more via integrations with third-party tools. 5: Quickly review & test code on GitHub: GitHub Actions lets you integrate any number of third-party testing tools directly into your workflow in your repo—at any step. Moreover, GitHub Actions enables multi-container testing and “matrix builds,” which lets you run multiple tests on Linux, Windows, and macOS at the same time.
