Things people build with this

USE CASE 1

Automatically test and deploy code to Kubernetes whenever a developer pushes a commit, removing all manual steps.

USE CASE 2

Spin up a temporary live preview environment for every pull request so reviewers can test changes before merging.

USE CASE 3

Store all deployment configuration in Git so every change is versioned and rolling back means reverting a commit.

USE CASE 4

Extend the CI/CD pipeline by installing Jenkins X plugins for specific tasks like Git provider integration.

Requires a running Kubernetes cluster plus familiarity with GitOps, Tekton pipelines, and cloud infrastructure before you can run your first pipeline.

In plain English

Jenkins X is a system for automating software testing and deployment on Kubernetes, which is a platform for running applications in the cloud. The jx tool is the command-line interface that lets developers interact with Jenkins X 3.x from their terminal. When a developer pushes code or opens a pull request, Jenkins X can automatically run tests, build the software, and deploy it, removing a lot of manual steps from the release process. The project uses Tekton, a framework for defining these automated steps, and follows GitOps patterns, where the state of your running software is controlled by what is stored in a Git repository rather than by manual commands. This means the history of every deployment is tracked in version control, and rolling back is a matter of reverting a commit. One notable feature described in the project is preview environments: when someone opens a pull request, Jenkins X can spin up a temporary running version of the application so reviewers can test it live before the code is merged. This reduces the gap between writing code and seeing it work in a real environment. The jx command-line tool is modular. The core binary is kept small, and most capabilities are delivered through a set of separate plugins. Each plugin handles a specific concern, such as interacting with Git providers, managing API resources, or handling logging. The README points to an external reference site for the full list of available commands and plugins rather than listing them inline. The repository is written in Go and the README itself is brief, serving mainly as a navigation hub to the project website, plugin source code, and supporting libraries.
