A Quick Start to Jenkins

By Xandermar LLC, January 17, 2024

Getting started with Jenkins involves several steps. Jenkins is an open-source automation server used for building, testing, and deploying software. Here's a basic guide to help you get up and running with Jenkins:

1. Installation:

  • Download and install Jenkins on your server or local machine. You can find the latest version on the official Jenkins website.
  • Follow the installation instructions provided for your operating system.

2. Start Jenkins:

  • Once installed, start the Jenkins server. The default port is 8080, so you can access the Jenkins dashboard by opening a web browser and navigating to http://localhost:8080 (replace "localhost" with the server's IP address if it's installed remotely).

3. Unlock Jenkins:

  • During the first run, Jenkins will provide an initial password. You can find this password in the Jenkins server logs or the initial setup page.
  • Follow the on-screen instructions to unlock Jenkins.

4. Customize Jenkins:

  • Install recommended plugins or choose custom plugins based on your needs during the initial setup.
  • Set up an admin user and configure the necessary settings.

5. Create a New Job:

  • Click on "New Item" on the Jenkins dashboard to create a new job or project.
  • Provide a name for your job and choose the type of job (freestyle project, pipeline, etc.).

6. Configure Job:

  • Configure the job settings, including source code management (e.g., Git, SVN), build triggers, and build steps.
  • For a basic setup, you can start with a simple build step like executing shell commands.

7. Save and Build:

  • Save your job configuration and trigger a build manually to test if everything is set up correctly.
  • Review the console output for any errors or issues.

8. Explore Plugins:

  • Jenkins has a vast ecosystem of plugins that extend its functionality. Explore and install plugins that suit your requirements.

9. Configure Build Agents (Optional):

  • If you have a complex setup, you might need to configure build agents (slaves) to distribute build workloads.

10. Integrate with Version Control:

  • Integrate Jenkins with your version control system (e.g., GitHub, Bitbucket) for automatic triggering of builds.

11. Set Up Notifications (Optional):

  • Configure notifications for build results (success, failure) using plugins like Email Notification, Slack, etc.

12. Explore Jenkins Pipeline (Optional):

  • For more advanced workflows, consider using Jenkins Pipeline for defining your build, test, and deployment processes as code.

13. Security:

  • Implement security measures, including user authentication, authorization, and SSL if Jenkins is exposed to the internet.

14. Regular Maintenance:

  • Keep Jenkins and plugins up to date and perform regular backups of your Jenkins configuration.

This is a basic guide, and the specifics may vary depending on your use case. Jenkins has extensive documentation, so refer to it for detailed information on specific features and configurations: Jenkins Documentation.
