How do I install Jenkins?

Are you having trouble installing Jenkins? This tutorial will show you how to install Jenkins on your system.
Jenkins is the most widely used tool for continuous integration and continuous delivery on any platform. Jenkins’ Java capabilities can be used to leverage the various plugins to automate different operational aspects at the infrastructure layer. Recent developments in plugins have made Jenkins implementation a well-known success.
First, you need to determine the process for installing Jenkins. This article will give you a clear idea of the steps required to install Jenkins on Docker on Windows and Mac systems. This discussion will use Docker as the installation platform.

Learn about Jenkins Releases
Before we get into how to install Jenkins, let’s first look at the release lines. LTS and weekly are the two release lines for Jenkins. You can choose one or the other depending on your organization’s needs. Both release lines can be found with Docker containers, native packages, installers, war files, and Docker containers.
LTS (Long-Term Support) releases are chosen at an interval of 12 weeks after the regular releases. LTS releases are stable releases that are assumed to be stable for a certain period. These weekly releases are those that are created each week to deliver bug fixes and new features to plugin developers as well as users.
Get Started with the Installation
Let’s now look at the steps required to install Jenkins on a single machine or on a local machine. It is essential to note that the general operations of Jenkins follow a standalone application model with its own specific process with the in-built Java servlet container/application server. You should also know that Jenkins can be run in other Java servlet containers, such as Apache Tomcat and GlassFish, before you get started. However, advanced professionals will find the instructions for setting up such installations very useful. These steps will help you install Jenkins in different production environments.
Prerequisites for Jenkins Installation
Before we explain the installation process, the prerequisites are the most important information in any Jenkins tutorial. Let’s now look at the prerequisites for installing Jenkins.
Hardware Requirements
For Jenkins to be installed on an individual machine, it will require 256 MB RAM and 1GB hard drive space. It is important to note, however, that Jenkins can only be run as a Docker container if it has 1GB of hard drive space. For a small team, the hardware configuration should have more than 1 GB RAM. A small team should have a hard drive capacity of at least 50GB.
Software Requirements
Software requirements for Jenkins installation and configuration include references to Java, the web browser, and the operating system. For Java requirements, all new Jenkins versions must meet the following requirements.
Java 8 runtime environments include support for both 32-bit and 64-bit versions.
Jenkins does not support older Java versions such as Java 9, Java 10 or Java 12.
These requirements apply to all components of the Jenkins system, such as the Jenkins master and CLI agent, and all types of agents. Two JDKs (or JREs) are used by Jenkins project to perform a full test flow. These are OpenJDK JDK/JRE8-64 bits and OpenJDK JDK/JRE11-64 bits. You can use JRE/JDKs of other vendors on Jenkins without any restrictions.
Compatibility with Web Browser
Web browser compatibility is the next crucial aspect of installing Jenkins. There are three categories of web browsers that Jenkins supports. The first is that the first level of web browser qualification for Jenkins aims to fix browsers proactively and provide a similar user experience across all browsers. The second level of the web browser support model for Jenkins’ software requirements is the one that accepts patches to fix issues.
It should also show the best effort to ensure at least one method of performing any action. There are no guarantees at the final level of web browsers within the support model for Jenkins. This implies that Jenkins will accept patches from such browsers only if they’re low-risk. For Jenkins installation, Google Chrome, Apple Safari, and Mozilla Firefox are the best browsers.
