Learn DevOps with Jenkins All in One Guide

Install and explore Jenkins, the open source continuous integration and devops tool written in Java, with flexible deployment options, plugins, and container support.

Learn to install Jenkins on Tomcat via a lightweight Tomcat server using vagrant, including port forwarding from host 8080 to guest 8080 and provisioning options.

Install Jenkins as a war on Tomcat by placing Jenkins.war in Tomcat’s webapps and accessing it at localhost:8080, secured with the generated strong password; compare LTS and weekly builds.

Install Jenkins as a standalone Debian package on Ubuntu using apt-get, import the key, add the repository, and start the Jenkins service.

Run Jenkins directly from the Jenkins.war file using java, without installation. Use a vagrant environment with a shared /vagrant folder to move Jenkins.war and access via localhost:8888.

Explore multiple Jenkins installation options, including standalone binaries, war deployments, and docker containers, and learn how to run Jenkins in a container with port forwarding and volume mapping.

Create your first Jenkins job in an Ubuntu vagrant environment using a freestyle project and an execute shell step to write hello world to a file.

Expand a Jenkins job by configuring post build actions and installing the email extension plugin to send SMTP notifications. Manage plugins and configure the SMTP server to specify recipients.

Explore how Jenkins shows job results on the dashboard with status icons that reflect recent build stability, including how to view console output for failure messages and scheduled runs.

Learn to build a periodic backup in Jenkins by archiving /temp/important into a dated tar.gz with a shell script and timestamp, using a freestyle project and cron-like scheduling.

Learn to schedule periodic Jenkins jobs using minute and hour fields with ranges, asterisks, slashes, and discrete values, and use hash to spread load evenly.

Explore Jenkins security with global security settings, authentication options, and matrix based authorization, including project based security and block inheritance to finely control access.

Learn how design and branching strategies drive reliable Jenkins continuous integration pipelines, using master, integration, and feature branches, and automated builds and unit tests to safely integrate code.

Explore how Jenkins automates the workflow between feature, integration, and master branches, building, unit testing, integration testing, and static analysis to ensure code quality before merging.

Learn how a Jenkins feature pipeline automates continuous integration by building feature branches with Maven, testing, and merging changes into the integration branch using Git.

Discover language independent development using Jenkins and Maven to implement continuous integration across compiled and interpreted languages, leveraging frameworks, IDEs, and seamless database integration.

Maven provides a consistent build process and automatically downloads missing dependencies. See how the pom.xml defines model version 4.0.0, project information, groupId, artifactId, version, packaging, and dependencies.

Discover the maven lifecycle by building a hello world Java project in Jenkins, including downloading the sample, compiling with mvn, running unit tests with JUnit, and producing a jar.

Learn to build, test, and deploy a Java application with Jenkins by using the Maven lifecycle, implementing mvn commands, and managing Git branches.

Configure the first Jenkins pipeline between the feature and integration branches, poll for changes, build and test with Maven, and merge to integration, with Git and JDK configured.

Build and test a Jenkins job that polls the feature one branch of a git repository, runs maven verify, and reports successful unit tests for the hello world application.

Demonstrate a two-step Jenkins pipeline that drives continuous integration by merging a feature one build into the integration branch after successful tests, using git merge and build triggers.

Learn to build real-world Jenkins continuous integration workflows that poll feature branches, run Maven builds and unit tests, and merge into the integration branch, handling git conflicts when needed.

Upgrade Jenkins by replacing the jenkins.war with a newer version across install forms. Restart the Jenkins service and verify deployment; locate the war file with find if needed.

Track Jenkins job configuration changes with the Job Config History plugin, view diffs, and revert to prior versions of the config.xml.

Configure audits and logging in Jenkins with the audit trail plugin to log console and file messages, optionally to a syslog server, with log rotation and file naming patterns.

Install and customize Jenkins themes by using the simple theme plugin, then apply CSS and optional JavaScript URLs to change colors, icons, and fonts for your devops workflow.

Learn to implement continuous integration and devops with Jenkins through hands-on installation options, creating jobs, and integrating Maven, version control, and post-build actions.
