What is github?
- GitHub is a web-based platform that provides hosting for version control repositories.
- It offers a collaborative environment for software developers, allowing them to store, manage, and track changes to their codebase.
- GitHub utilizes Git, a distributed version control system, to enable multiple developers to work on the same project simultaneously while keeping track of each change made to the code.
- GitHub provides various features and tools to facilitate software development and collaboration.
- These include repository management, issue tracking, project management boards, pull requests, code reviews, continuous integration and deployment (CI/CD) workflows, and more.
- It serves as a centralized hub where developers can collaborate, contribute to open-source projects, and showcase their work to the broader software development community.
Repository Setup
To set up a repository follow below instructions:
1. Sign in to your GitHub account or create a new account if you don’t have one
2. Once you’re logged in, click on the “+” sign located in the top-right corner of the GitHub interface. A drop down menu will appear.
From the dropdown menu, select “New repository.” You will be directed to the “Create a new repository” page.
3. On the “Create a new repository” page, you’ll need to provide some information about your repository:
4. Repository name: Choose a descriptive name for your repository that reflects the project or application it represents.
5. Description: Optionally, provide a brief description of your repository to help others understand its purpose.
6. Public or Private: Select whether you want your repository to be public (visible to everyone) or private (restricted to collaborators).
7. Initialize this repository with a README: Check this option if you want to create an initial README file for your repository.
Once you’ve entered the required information, click on the “Create repository” button at the bottom of the page.
Congratulations! You have successfully created a new repository on GitHub. The repository page will now be displayed, providing you with important details and options for managing your repository.
Version Control and Branching Strategy
- Initialize Version Control: Ensure that Git is installed on your local machine. If not, download and install Git from the official website (https://git-scm.com/).
- Clone the Repository: To start working with a repository on your local machine, clone it using the following command in your terminal or Git Bash:
git clone <repository_url>
Replace <repository_url> with the URL of your GitHub repository. This command will create a local copy of the repository on your machine.
- Create a Branch: Before making changes to the codebase, create a new branch. Branches provide isolation for different features or bug fixes. Use the following command to create a new branch:
git checkout -b <branch_name>
Replace <branch_name> with a descriptive name for your branch, such as “feature/login-page” or “bugfix/issue-123”.
- Work on the Branch: Switch to the newly created branch using the command
git checkout <branch_name>
Make your desired changes to the code, add new files, or modify existing ones.
- Stage and Commit Changes: Once you have made the necessary changes, stage the modified files using the command:
git add .
This command stages all the changes in the current directory. Alternatively, you can specify individual files or directories to stage.
- Push the Branch: To make your branch and its changes visible on GitHub, push the branch to the remote repository:
git push origin <branch_name>
This command pushes your branch to the remote repository, allowing others to see and review your changes.
- Branch Cleanup: After merging the branch, you can delete it to keep your repository organized. This can be done on the GitHub repository page by clicking on “Delete branch” in the pull request or by using the following command locally:
git branch -d <branch_name>
Continuous Integration and Delivery (CI/CD)
- When GitHub is integrated with a CI/CD pipeline, build, test, and deployment procedures are automated, resulting in regular and trustworthy software releases.
- Pick a CI/CD tool, such as Jenkins, CircleCI, or GitHub Actions, that fits your needs. Set up your CI/CD procedures to start when certain things happen, like code pushes or merges of pull requests.
- Automate processes like containerization, static code analysis, testing, code compilation, and artefact deployment to the target environment.
- GitHub offers its own built-in CI/CD system called GitHub Actions, which allows you to define workflows using YAML configuration files.
- Alternatively, you can integrate GitHub with popular CI/CD tools like Jenkins, CircleCI, or Travis CI. Choose the tool that best aligns with your team’s requirements and familiarity.
Infrastructure as Code (IaC)
- Infrastructure as Code is a core principle of DevOps, enabling the provisioning and management of infrastructure resources through code.
- GitHub provides support for popular IaC tools like Terraform and AWS CloudFormation, allowing infrastructure configurations to be versioned and managed alongside application code.
- This integration ensures that infrastructure changes are transparent, auditable, and reproducible, promoting consistency across environments.
- Select an IaC tool that aligns with your infrastructure needs and preferences.
- Popular choices include Terraform, AWS CloudFormation, Azure Resource Manager (ARM) templates, and Google Cloud Deployment Manager.
- These tools enable you to describe infrastructure resources and their configurations in a declarative manner.

Issue Tracking and Project Management
- GitHub’s issue-tracking capabilities enable efficient project management within your DevOps workflow.
- Use GitHub Issues to capture and prioritize tasks, track bugs, and manage feature requests. Organize work items using labels, milestones, and project boards.
- Align your project boards with your preferred project management methodology, such as Kanban or Agile, to visualize and track the progress of tasks across development and operations.
- GitHub provides a robust issue-tracking system that allows you to create, assign, track, and manage issues throughout the development lifecycle.
- Click on the “Issues” tab in your GitHub repository and click on the “New issue” button. Provide a clear title and description for the issue, assign it to the appropriate team member, and apply labels to categorize and prioritize the issue (e.g., bug, feature, enhancement).
Security and Compliance
- DevOps environments require robust security and compliance measures.
- GitHub offers several features to address these concerns.
- Enable code scanning tools, such as GitHub CodeQL or third-party integrations like SonarQube, to analyze code for security vulnerabilities and coding best practices.
- Leverage GitHub Actions or integrations with security testing tools like Snyk to identify and remediate vulnerabilities in your dependencies.
- Utilize GitHub’s access controls, two-factor authentication, and security settings to ensure proper access management.
Integrations and Ecosystem
GitHub’s extensibility through integrations and the wider ecosystem is a valuable asset in implementing DevOps practices. Explore the GitHub Marketplace for integrations with CI/CD tools, code quality analysis, monitoring, and notification systems that align with your DevOps toolchain. Leverage third-party integrations or build custom integrations using GitHub APIs to connect with other systems and automate workflows seamlessly.
- GitHub Actions: GitHub’s native CI/CD solution allows you to define custom workflows using YAML configuration files. It integrates directly with your GitHub repositories, enabling
- Jenkins: Jenkins is a popular open-source automation server that can be integrated with GitHub. It provides extensive capabilities for building, testing, and deploying software, allowing you to configure complex CI/CD pipelines.
- CircleCI, Travis CI, and others: GitHub integrates with various cloud-based CI/CD services, enabling seamless integration and automation of your build and deployment processes.
