Cloud Computing Microsoft Azure Google Cloud Platform Operating System Computer Network Jenkins is an open-source automation server used to build, test, and deploy software efficiently. It is widely used in DevOps to automate Continuous Integration (CI) and Continuous Delivery (CD) pipelines. Automates build, test, and deployment processes. Integrates with various tools like Git, Maven, and Docker. Improves development speed, reliability, and software quality. Before Jenkins, software development processes were slower and less efficient. Developers working across different locations often faced integration conflicts, delays, and increased bugs. Code integration happened late, causing major conflicts. Testing was delayed until development was complete. Bug fixing became time-consuming and frustrating. Jenkins transformed this process by introducing automation into development workflows. Automates builds and testing whenever code is committed. Detects bugs early in the development cycle. Enables faster and more reliable software releases. Allows developers to integrate code frequently without conflicts. Before starting with Jenkins, having a basic understanding of software development and DevOps concepts will help you use it more effectively. DevOps Life Cycle Software Development Life Cycle What Is Jenkins Primarily Used For In DevOps? Getting Started with Jenkins In this section, you will learn the core concepts of Jenkins, including its purpose, the basics of continuous integration and delivery, and an introduction to pipelines as code. What Is Jenkins? What Is Continuous Integration? What Is Continuous Delivery? Introduction To Jenkins Pipeline As Code (Jenkinsfile) Installation & Update of Jenkins Jenkins is built using Java, so it is necessary to install Java on your system before setting up Jenkins. Once Java is installed, Jenkins can be easily installed on the desired operating system. Refer to the official guides for installing Java and Jenkins on different platforms, as well as for updating Jenkins to the latest version to ensure improved performance and security. How to Download and Install Java for 64-bit machine? Installation of Jenkins in Cent OS Installing Jenkins on Windows Installing and configuring Jenkins on Arch-based Linux Distributions (Manjaro) How To Update Jenkins In Linux? How to install and Configure Jenkins in AWS EC2 Jenkins - Git, Maven, and Docker Configuration, Integration & Setup After installing Jenkins, the next step is to integrate it with tools like Git, Maven, and Docker to set up a complete CI pipeline. Jenkins automates code management, builds, testing, and deployments, making the development process faster and more efficient. How to Configure Git in Jenkins How to Configure Maven in Jenkins How to Configure Docker in Jenkins Jenkins - Credentials & Port Managing ports and passwords properly keeps Jenkins secure and ensures it works smoothly with other services. Jenkins offers a Credentials Plugin that allows you safely store and manage passwords, API keys, and sensitive information. Learning how to configure ports and manage credentials helps protect your Jenkins environment from unauthorized access and keeps your automation processes secure and stable. What Is The Default Jenkins Password? How to Add GIT Credentials in Jenkins? How To Change The Port In Jenkins? Projects Or Jobs Jenkins projects (jobs) are the basic units of work that define tasks Jenkins performs based on triggers or configurations. Learn to create and configure them to automate build and deployment workflows. Creating And Configuring Freestyle Projects In Jenkins How To Build Java Application In Jenkins? Continuous Integration and Continuous Delivery Pipeline (CI/CD Pipeline) CI/CD pipelines automate the flow of code from development to production by handling integration, testing, and deployment. This speeds up releases while maintaining quality and reliability. In this section, you will learn how Jenkins manages CI/CD pipelines and how to create pipelines for different applications. Understanding Jenkins CI/CD Pipeline And Its Stages How to Make a CI-CD Pipeline in Jenkins? Setting Up A CI/CD Pipeline For PHP Applications Using Jenkins How to create a Jenkins declarative pipeline? Managing Plugins Plugins make Jenkins more useful by letting you add new features, connect with other tools, and automate tasks in your CI/CD pipelines. This section will help you learn the basics of Jenkins plugins and how to use them well. What are Jenkins Plugins? How To Customize Jenkins Functionality With Plugins ? How To List All The Jenkins Plugins Configured In CLI ? How to Solve “Some plugins failed to install properly, you may retry installing…” in Jenkins? Unit Testing (Code Quality Review) Now that you have learned to use plugins, the next step is testing your code. Testing ensures your software works correctly and remains maintainable. In this section, you will use the JaCoCo plugin to run tests and generate coverage reports, helping you identify issues early and keep your code reliable. What Is JaCoCo Plugin In Jenkins? How to Generate Code Coverage Report with JaCoCo in Java Application? Security is essential in Jenkins to protect sensitive data and prevent unauthorized access. Proper security practices help keep your CI/CD pipeline safe and reliable.

In this section, you will learn basic security measures, access control management, and how to reset Jenkins security settings using the command line if needed. Jenkins – Security Best Practices Managing Security Settings And Access Controls In Jenkins How To Reset Jenkins Security Settings From The Command Line ? Jenkins - Notification Jenkins notifications help users track build status, test results, and other important events. It provides built-in plugins to send alerts for these updates. How To Integrate Jenkins With Slack Jenkins - Triggering Builds Remotely Jenkins simplifies build triggering by enabling automation and remote execution. Earlier, builds were triggered manually, which was time-consuming Jenkins allows remote and automatic build triggering using API tokens or webhooks Supports manual, scheduled, and event-based triggers for automation How To Configure Build Periodically In Jenkins? How To Configure Poll SCM Jenkins? How To Trigger Jenkins Builds Remotely And To Pass Parameters? Jenkins - Restart(Build Number, Server, Security) Restarting Jenkins involves safely rebooting the server, managing security settings, and resetting build numbers if needed. This section explains how to restart Jenkins, reset security via the command line, and maintain a stable environment. How To Restart Jenkins Manually? How To Reset Jenkins Security Settings From The Command Line? How To Reset Build Number In Jenkins? Jenkins - Master-Slave Configuration Master–Slave (Agent) configuration in Jenkins distributes workloads across multiple machines for efficient build execution. The master node manages and schedules jobs, while slave nodes (agents) execute the tasks. How to Setup a Slave Agent For the Master in Jenkins? Jenkins Master And Slave Configuration Using AWS EC2 Instance Jenkins VS Other CI/CD Tools While Jenkins is widely used for CI/CD, exploring alternatives helps choose the best tool for your needs. Comparing tools like Travis CI, CircleCI, GitLab CI, and Bamboo highlights differences in features, scalability, and integration. Jenkins vs Travis Cl Jenkins vs Team City Jenkins vs Gitlab Jenkins vs Spinnaker Jenkins VS Bamboo Jenkins vs Maven Jenkins vs Kubernetes The Jenkins Command Line Interface (CLI) lets you interact with Jenkins directly from the terminal or scripts. It provides commands to automate tasks, manage jobs, and perform administrative actions efficiently, making repetitive operations faster and easier.
