Certified Jenkins Engineer (CJE) Certification Training

The Certified Jenkins Engineer exam validates your skills, knowledge, and experience as a Jenkins professional. Once you clear the exam, it means that you have a proven level of proficiency in Jenkins. The abilities tested in the Certified Jenkins engineer exam are:

• Basics of the CI/CD/Jenkins concepts
• Using Jenkins as a build and integration server 
• Automation of the project development and deployment using Jenkins
• Implementation of Continuous Development as Code best practices

Roles and responsibilities of a Jenkins Engineer are:

• Planning and deployment of the high availability solutions for DevOps services.

• Installation, configuration, and extension of different software systems
• Installation, configuration, and extension of web servers,  SQL and NoSQL databases, application frameworks, distributed messaging systems, and caches 
• Automation of  the configuration, provisioning, and monitoring of software and tools for continuous integration servers, developer workstations, cloud infrastructure, computing clusters, embedded devices, and other systems
• Automation of the continuous integration, compilation, testing, and distribution of multiple software components
• Engineer tools and systems to support the development, integration, and verification of the complex software systems 
• Development and maintenance of the large data and file storage solutions
• Work closely with developers to tailor tools and solutions for rapidly evolving needs
• Introduce and implement best practices for the new feature development while maintaining the proper functioning of the software products  

The fingerprint of a file is MD5 checksum. It is stored as an xml file for each artifact on which fingerprinting is enabled. Significance of fingerprints in Jenkins is that it: 

• Helps to track the file/artifacts across the builds/jobs 
• Allows to trace the source and version of file/artifact
• Checks whether artifacts are originated from the same job

Certified Jenkins Engineer exam is designed to test the technical abilities of candidates to automate the process of development and deployment of a project by using Jenkins., Here is the list of important topics to focus on while preparing for the Certified Jenkins Engineer exam:

• Jenkins Fundamentals
• Jenkins Administration
• Jenkins Build Technologies: Pipeline
• Jenkins Build Technologies: Freestyle

A Jenkins freestyle project is a typical repeatable build job or task that contains steps and post-build actions. Though you can only perform limited actions with such steps and post-build actions, Jenkins provides you many standard plugins with the freestyle project to overcome this problem. These plugins enable you to configure build triggers and offer project-based security for your Jenkins project.

Jenkins is an open-source automation server that offers a number of plugins to automate the development and deployment of any project. It is one of the most popular CI/CD tools that can not only be used as a build and integration server but also for the purpose of the automation task. Significance of using Jenkins involves:

• Open-source tool, free of cost
• Great community support
• Easy to install
• 1000+ plugins to ease your tasks
• Built with Java, so, it’s portable to all major platforms

• It's an open source tool
• Easy to configure
• Portable to major platforms
• A lot of plugins are available
