Jenkins Tutorial
What are Jenkins pipelines and how do they differ from freestyle projects?
Jenkins pipelines allow you to define your entire CI/CD process as code using a Jenkinsfile, enabling version control, code review, and automated testing of your pipeline. In contrast, freestyle projects are more flexible but less structured, allowing you to configure individual build steps using the Jenkins web interface.
How can I integrate Jenkins with version control systems like Git?
Jenkins integrates seamlessly with Git and other version control systems. You can configure Jenkins jobs to poll SCM repositories for changes, trigger builds automatically on code commits, or use webhooks to notify Jenkins of repository events. Additionally, Jenkins provides plugins for tighter integration with Git, enabling features like branch-specific builds and pull request testing.
What is the Dockerfile used for?
A Dockerfile acts as the blueprint for creating Docker images, providing a set of instructions for building a containerized application. These instructions define the environment, dependencies, and commands needed to construct the Docker image. Each instruction in the Dockerfile contributes to the creation of layers within the Docker image. As the number of layers increases in the Dockerfile, so does the size of the resulting Docker image. In essence, the Dockerfile serves as the source code for generating Docker images, enabling consistency and reproducibility in containerized deployments.
What is entrypoint in Dockerfile?
Entrypoint in the Dockerfile is an instruction that will be executed when the docker container is started by using the docker image. It is an primary executable process for the container.
How to delete a Docker image?
- Command used to delete the docker image is “docker rmi”.
- Command used to force remove the docker image is “docker rmi -f <imageId/Name>”
Jenkins Tutorial
Jenkins is an open-source automation server by which you can automate the building, testing, and deployment of the application to different servers like development, testing, and production. Jenkins is primarily used for the continuous integration (CI) and continuous Deployment (CD) pipelines.
Each tutorial section includes practical exercises and real-world examples, helping you learn by doing and gaining hands-on experience along the way. Jenkins tutorials are going to help all the software testers with the help of JaCoCo Plugin and also it will help the developers to deploy their code fast and efficiently by which they can deliver the new updates to the end users as soon as possible.
