After completing this internship at Linux world informatics under the guidance of My Mentor Mr. Vimal Dga Sir, I am feeling very glad before starting the internship I did not know anything about Jenkins where it is used, why is it so important in today's industry. I thought it might be a basic internship about Jenkins but after 3 -4 lectures I realized that it's more than what I expected . Sir taught us not only to create jobs and nodes in Jenkins but also its integration with git Kubernetes, pipeline structure, and Managing users and Security..

I thank Vimal Daga sir and LinuxWorld Informatics Pvt. Ltd. for everything I learned…
