Mastering DevOps: A Journey with Jenkins Freestyle Projects Day - 23
Hey Hashnode DevOps Community! 👋
Exciting updates from the #90daysofdevops journey! We're delving into the realm of Continuous Integration (CI) and Continuous Delivery (CD), with a focus on Jenkins Freestyle Projects. Let's explore this dynamic challenge and unravel the potential of DevOps skills.
## Understanding CI/CD
In the intricate world of DevOps, Continuous Integration (CI) is the practice of automating code changes' integration from various developers into a central codebase. Jenkins, our trusted ally, facilitates this process, aiming to find bugs swiftly, simplify code integration, enhance software quality, and expedite releases. Following CI, Continuous Delivery (CD) ensures error-free, automated release processes by running tests in a staging environment before deploying changes to production.
## The Essence of a Build Job
Jenkins thrives on automation, and at its core are Build Jobs. These jobs encompass configurations for specific tasks in the application building process. From gathering dependencies to testing and deploying code, Jenkins supports various build job types, with freestyle projects taking center stage.
## Unveiling Freestyle Projects
A Jenkins freestyle project provides developers with the flexibility to build, test, and deploy software seamlessly. Let's break down a couple of tasks to showcase the power of Jenkins Freestyle Projects:
### Task-01: Containerizing Your App
1. **Create an Agent**: Establish an agent for your app, previously deployed from Docker.
2. **Freestyle Project Setup**: Create a new Jenkins freestyle project for your app.
3. **Build Section Configuration**: In the "Build" section, add a step to run "docker build" for creating the image.
4. **Container Deployment**: Add a second step to execute "docker run" for launching a container using the built image.
### Task-02: Docker Compose Magic
1. **Jenkins Project Creation**: Develop a Jenkins project to execute "docker-compose up -d" for starting multiple containers defined in the compose file.
2. **Cleanup Automation**: Implement a cleanup step in the Jenkins project to run "docker-compose down" for stopping and removing containers defined in the compose file.
These tasks go beyond mere steps; they orchestrate a symphony of automation, enhancing efficiency and reliability in your DevOps pipeline.
In conclusion, Jenkins Freestyle Projects offer a playground for DevOps engineers to exhibit their prowess in automating the building, testing, and deployment of applications. Embrace the challenges, master the tasks, and let Jenkins empower your DevOps journey!
Happy coding and automating,
