Jenkins + Docker Pipeline from GitHub

Tue, 10 Feb 2026 00:00:00 +0000

What I Built

I wanted Jenkins to pull code from GitHub, build a Docker image, and run a container automatically. This post is the pipeline I put together for that.

Goal: From Manual to Automatic

Manually, we usually do this:

Clone a GitHub repository
Run docker build
Run docker run
Check the output

With Jenkins, all of this happens automatically when the pipeline runs.

You click Build Now (or trigger from GitHub), and Jenkins does the rest.

Why I Wrote This

1. What is Jenkins? (Simple Explanation)

Jenkins is an automation server.

You can tell Jenkins to:

Get your code (for example from GitHub)
Run commands (build, test, scripts)
Show you if things passed or failed
