(deep dive into Jenkins )

Heh There!!, this blog is purely for those who are finding it hard to implement JenKins Lab , and wanna deep dive onto the tech behind (for solid understanding of the ‘things under the hood’ ) auto-CI/CD. Hope yu’ll enjoy this :))

Jenkins is a popular open-source automation server that is commonly used for continuous integration and continuous delivery (CI/CD) processes. Jenkins can indeed retrieve code from source code management (SCM) systems such as GitHub, and it can perform various tasks with the code, including building, testing, and deploying it.

Assignment 4(a) – Jenkins

(Creating a DevOps Pipeline, CI/CD tool)

so, the lab thing for Jenkins has finally come , till now i have ran the dockerfile (which basically will pull the Jenkins image from dockerHub ) given by college to install and utilize the Jenkins using the created dock img.

have done it and given a port number as 8070 to route all my traffic heading towards container to :8070 , ran this and got the admin password (default and generated by Jenkins) used it to log in onto Jenkins-online from there i have used the option called - “select and install plugins” to install the GitHub plugin for the seamless continuous integration and continuous deployment (Ci/CD)

basically the GitHub here will act as the - SCM ⇒ source code management tool

basically its now serving us like a “PROGRAMMER’s REPO” here , it’ll draw/take the code files or artifacts from the Git Rep that we define and it’ll automatically detect and does some actions for those triggers(newly commited codes)

However, Jenkins itself does not "push" code to a specific destination. Instead, Jenkins typically triggers various actions based on events, such as code changes being pushed to a GitHub repository. These actions can include fetching the latest code, compiling it, running tests, and deploying the application to a target environment

here abv for our lab we’ve selected the ‘new item’ to be a freestyle project , and there is the description of it :)
