Jenkins

This course discusses the open-source automation server, Jenkins.

About the Course

The learners of this course would be made to understand that this automation tool is written in Java and was created for the purpose of building, testing, and deploying software. Testing through this tool can be done continuously allowing for easier tweaks and changes across all software projects.  

The course introduces Jenkins to its learners with the aim of arming them with technical knowledge so that they may be able to assume the professional roles that require the employment of such. 

Who this Course is for?

This course is intended for professionals who are experienced in programming through Java and are interested in learning how to implement CI/CD pipelines. The learnings that they would derive from the course would expand their knowledge and technical know-how, allowing them to assume more roles in related fields. 

Prerequisites

It is recommendable for the professionals wanting to enlist with the course to have the following:

- A bachelor's degree in Computer Science, Information Technology, or equivalent

- In-depth knowledge of programming through the use of the language, Java

- At least 1 to 2 years experience of working as a Software Developer or a Programmer

Jenkins Overview

Part 1 of 7: Install and Configure

This lesson details how the learners can Install and Configure Java across all operating systems. 

This lesson informs learners that the Jenkins project comes out with two (2) release lines, namely Stable (LTS) and Regular (Weekly), and that they can choose between the two depending on the needs of their workplace or organization.

The lesson walks the learners through the process of downloading and installing Jenkins on their device with consideration to the specifications of the hardware and software that they use.

Part 2 of 7: Docker and AWS

This lesson discusses how Jenkins is integrated effectively with AWS through a step-by-step procedure. This goes on to detail how the server can automate deployments through the EC2. 

This lesson also discusses how Docker is used with the Jenkins Pipeline.

Part 3 of 7: Ansible

This lesson discusses what Ansible is. Learners are to find out that this is an automation tool for the target environment and application deployment.

The lesson details how Ansible is integrated with Jenkins.

Part 4 of 7: Security and Jobs

This lesson discusses the security configuration that Jenkins sets in place. 

The lesson also details what a "Job" is in the context of Jenkins. Here, the learners would understand that the term "Job" and "Project" is interchangeably used but simply refer to the tasks that may be run that are controlled and monitored by the automation tool.

Part 5 of 7: Maven and GIT

This lesson details what Maven is. The learners are informed that Maven is a build tool created for the management of dependencies and software lifecycle. This also permits its users to create additional tasks alongside other tasks such as testing, packaging, installing, and deployment.

This lesson also introduces learners to GIT, a source code management system. The discussion informs them that Jenkins is able to function with Git through the use of a Git plugin. 

Part 6 of 7: DSL and Pipelines

This lesson details what DSL is. The learners are informed that the Job DSL is a well-known Jenkins plugin that permits configuration management "as code". Through it, programmers would be able to define jobs in programmatic form without exerting too much effort.

This lesson also differentiates DSL from a Pipeline. Learners are informed that Pipeline pertains to Jenkins Jobs that are enabled by the Pipeline plugin that is built with text scripts that make use of a Pipeline DSL.

Part 7 of 7: Put it All Together

This lesson details how all the discussed functions within Jenkins work together to allow efficient usage of the automation server.
