How to Deploy Jenkins on Ubuntu/Linux
Jenkins is an open-source automation tool that is used for building, testing, and deploying software. It is written in Java and is often used for continuous integration and continuous delivery (CI/CD) workflows. Jenkins can be used to automate various tasks, such as building and deploying code, running tests, and monitoring the performance of software applications. It also has a wide range of plugins available that can be used to integrate with other tools and systems.
Why to Use Jenkins CI/CD
Using Jenkins for CI/CD (Continuous Integration and Continuous Delivery/Deployment) provides several benefits:
- Automation: Jenkins automates the process of building, testing, and deploying code, which can save a lot of time and effort.
- Early error detection: By continuously building and testing code, Jenkins can help identify and fix errors early in the development process, which can save time and reduce costs.
- Faster time to market: By automating the deployment process, Jenkins can help speed up the delivery of new features and updates to customers.
- Improved collaboration: Jenkins allows developers to work on different features and fixes simultaneously and merge them into a single codebase, which can improve collaboration and increase productivity.
- Better quality: By continuously testing code, Jenkins can help ensure that code changes don’t break existing functionality, which can help improve the overall quality of the software.
- Increased agility: Jenkins can help teams to be more responsive to changing requirements and quickly adapt to new technologies and trends.
- Version Control: Jenkins can be integrated with version control systems such as Git, SVN, and others, which allows developers to track changes, maintain a history of builds and rollback to previous versions.
- Easy to monitor and track: Jenkins provides detailed reporting and notifications on the build and deployment process which makes it easy to track the progress and identify any issues that arise.
Below are the detailed steps and commands for installing Jenkins:
- Step 1: Add the Jenkins package repository to your system:
wget -q -O - https://pkg.jenkins.io/debian/jenkins.io.key | sudo apt-key add -
sudo sh -c 'echo deb http://pkg.jenkins.io/debian-stable binary/ > /etc/apt/sources.list.d/jenkins.list'
Adding the Jenkins package repository to your system is necessary in order to install and update Jenkins on your system. There are several reasons to add the Jenkins package repository:
Stable releases: The Jenkins package repository provides stable releases of Jenkins, which are thoroughly tested and considered safe for production use.
Automatic updates: By adding the Jenkins package repository to your system, you can set up automatic updates for Jenkins, which ensures that your installation is always up to date with the latest security patches and features.
Easy installation: Adding the Jenkins package repository to your system allows you to use the package manager of your operating system to easily install and manage Jenkins.
- Step 2: Update your package manager and install Jenkins:
sudo apt-get update
sudo apt-get install jenkins
The reasons to update the package manager and install Jenkins are:
Latest version: Updating your package manager ensures that you have the latest version of Jenkins available for installation.
Security updates: Updating your package manager ensures that you have the latest security patches and updates for Jenkins.
Easy installation: Using the package manager to install Jenkins makes the installation process simple and straightforward.
- Step 3: Start the Jenkins service:
sudo systemctl start jenkins
- Step 4: Verify that Jenkins is running and accessible
