Introduction to GitLab

GitLab is a web-based DevOps platform that provides a complete set of tools for software development, continuous integration, and collaboration. It is built on top of Git, the popular distributed version control system, and extends its capabilities to cover the entire software development lifecycle. GitLab is designed to be an all-in-one solution, making it a popular choice for many development teams and organizations.

Key features and components of GitLab include:

  • Git Repository Management: GitLab offers a powerful and user-friendly interface for managing Git repositories. Developers can create repositories, push code, manage branches, and handle merge requests efficiently.
  • Continuous Integration/Continuous Deployment (CI/CD): GitLab provides built-in CI/CD capabilities. Developers can define pipelines to automate building, testing, and deploying applications. This ensures that code changes are automatically tested and delivered to production environments with ease.
  • Code Review and Collaboration: With GitLab's merge requests, developers can propose changes to the codebase, and team members can review, discuss, and collaborate on the changes before merging them into the main branch.
  • Issue Tracking and Project Management: GitLab includes a robust issue tracking system that allows teams to create, assign, and manage tasks, bugs, and feature requests. It also provides project management tools like milestones, epics, and burndown charts.
  • Container Registry: GitLab has a built-in container registry where developers can store Docker images for their applications, making it easy to manage containerized deployments.
  • Security and Compliance: GitLab prioritizes security and provides features like Static Application Security Testing (SAST), Dependency Scanning, Container Scanning, and more to help identify and address security vulnerabilities.
  • Kubernetes Integration: GitLab offers seamless integration with Kubernetes, allowing developers to deploy and manage applications on Kubernetes clusters directly from GitLab.
  • GitLab Pages: This feature enables the easy creation of static websites directly from GitLab repositories, useful for documentation and project websites.
  • GitLab Runners: These are agents that execute the CI/CD pipelines defined in GitLab, either on shared runners provided by GitLab or on self-hosted runners.
  • Self-Managed or SaaS: GitLab can be deployed as a self-managed solution on-premises or on a cloud server of your choice. Alternatively, GitLab offers a SaaS version (GitLab.com) for teams who prefer a cloud-hosted solution.

GitLab comes in different editions, including a free Community Edition and a more feature-rich Enterprise Edition that offers additional functionality for larger teams and organizations. The Community Edition is open-source, allowing users to access and modify the source code.

Overall, GitLab has gained popularity for its versatility, integrated features, and focus on streamlining the DevOps workflow, making it a valuable tool for software development teams of all sizes.

Maven Create and Build Artifacts

In Maven, you can create and build artifacts using the package phase of the build lifecycle. The package phase is responsible for taking the compiled code and other project resources and packaging them into a distributable format, such as a JAR (Java Archive), WAR (Web Application Archive), or other custom formats. Here are the steps to create and build artifacts using Maven: Configure the Build Output: In your project's pom.xml file, you need to configure the output of the build. This includes specifying the type of artifact you want to create (e.g., JAR, WAR) and any additional resources to include. You do this in the <build> section of your pom.xml: <build>     <finalName>my-artifact</finalName> <!-- Name of the artifact without the extension -->     <plugins>         <!-- Plugin configurations for creating the artifact -->         <!-- For example, maven-jar-plugin or maven-war-plugin -->     </plugins> </build> Depend

Experiment No. 5 Title: Applying CI/CD Principles to Web Development Using Jenkins, Git, and Local HTTP Server

  Experiment No. 5 Title: Applying CI/CD Principles to Web Development Using Jenkins, Git, and Local HTTP Server  Objective: The objective of this experiment is to set up a CI/CD pipeline for a web development project using Jenkins, Git, and webhooks, without the need for a Jenkinsfile. You will learn how to automatically build and deploy a web application to a local HTTP server whenever changes are pushed to the Git repository, using Jenkins' "Execute Shell" build step. Introduction: Continuous Integration and Continuous Deployment (CI/CD) is a critical practice in modern software development, allowing teams to automate the building, testing, and deployment of applications. This process ensures that software updates are consistently and reliably delivered to end-users, leading to improved development efficiency and product quality. In this context, this introduction sets the stage for an exploration of how to apply CI/CD principles specifically to web development using J
