Getting started with Jenkins and Node
All my latest articles can be found at the RisingStack blog.
What is Jenkins?
Jenkins is an application that monitors executions of repeated jobs, such as building a software project. Jenkins focuses on two main areas:
- building/testing software projects continuously
- monitoring executions of externally-run jobs.
Jenkins is great for setting up continuous integration/deployment. It is written in Java, but is a general purpose tool, so setting up with Node is a piece of cake.
Preparing the server
In order to test our Node projects with Jenkins, we will need Jenkins, Node and Git installed. There is a detailed manual on how to setup it on various systems here.
Also, if you are using ansible, the following simple playbook should do the trick:
# This playbook deploys Jenkins
- name: Setting up roles
nodejs_version : “0.11.13"
If everything went ok, you should be seeing Jenkins’ welcome screen at your server’s 8080 port.
Setting up Jenkins
First, set up a user at Manage Jenkins > Manage Users.
By default, Jenkins does not use any authentication — fix that asap! Go to Manage Jenkins then click Setup Security.
Here check the following items:
- Jenkins’ own user database (but not Allow users to sign up)
- Matrix-based security
Make sure, the Git plugin is installed too (Manage Jenkins > Manage Plugins).
Now you should be good to go!
Setting up your first Node project
To do so, click on New Item, then choose Build a free-style software project.
At the next dialog, go for Source Code Management and choose Git (or any other). Here, set up the necessary credentials, then choose Add build step > Execute Shell.
That’s it! After clicking Save then Build now, your first build should start! ☺
In the next post we will discover how pipelines can be built in Jenkins for continuous integration/delivery.
