Creating a Jenkins Pipeline Job

How to create the pipeline job that runs your Jenkinsfile.

Steps

1. Jenkins dashboard → New Item → give it a name → choose Pipeline → OK.
2. In the Pipeline section, choose:
   • Pipeline script from SCM → SCM = Git → paste your forked repo URL
   • Branch = main · Script Path = Jenkinsfile
   
   (This tells Jenkins to read the Jenkinsfile from your repo.)
3. Save → Build Now.
4. Watch Stage View / Console Output for each stage.

Quick-demo alternative: choose Pipeline script and paste the Jenkinsfile contents directly into the box instead of pulling from SCM.

Gotchas

• main vs master — the branch name must match your repo.
• The first build may be slow (it pulls base images like node:18-alpine and nginx:alpine).

Then it runs the pipeline defined in [[jenkins-jenkinsfile-explained]]. Prerequisites: [[jenkins-install]] and [[jenkins-docker-hub-credentials]].
