So in the repository we will start by opening up the file config/jenkins.yml: jenkins: systemMessage: "Welcome to Jenkins for the Spring Project!" numExecutors: 4 mode: NORMAL scmCheckoutRetr圜ount: 3 labelString: "mjovanc" # we need to specify something here that we will define in our pipeline jobs, choose whatever name you want primaryView: all: name: All tool: jdk: installations: - name: "OpenJDK 16" properties: - installSource: installers: - zip: subdir: "/var/jenkins_home/tools//OpenJDK_16/jdk-16.0.1" url: "" jobs: - script: | job('seedjob-mjovanc') If there is some mistakes please add a comment and I will answer as quick as I can and correct the mistake. So my goal is to show you now what you need in a basic way. I actually tried to find out about JCasC but there was problem finding good tutorials, thorough ones that goes through every step needed to do this. This is something that takes a long time if you have a bigger project and could lead to a lot of problems with delivery of the product you are building. What if something happens to the server and we need to replicate a new server with Jenkins? Then we would need to manually add them again inside the web UI and install the plugins manually. So why do we need something called Jenkins Configuration as Code? Just imagine the scenario that you need to install a Jenkins server manually and have to input the configuration inside the web UI of Jenkins. There is a lot to unpack in this tutorial so grab a refreshing beverage once in a while. We will start by looking at the Jenkins Configuration as Code (JCasC) part so we will clone the repository and we will go through each file respectively what they do and why we need them. Each of them can contain specific scripted code that performs the required operations.In this tutorial we will go through the steps to setup a Jenkins server using Docker and Docker Compose to be able to build a Spring Boot application from a GitHub repository. Here we are defining three stages – Build, Test, and Deploy. ![]() Stage block descriptions are displayed in the Jenkins UI. These are optional, but highly recommended because they make it easy to understand the tasks or steps occurring in each stage. To begin with, we use the node statement, which says that this pipeline and any of its stages should be run on any available Jenkins agent. Here is a simple example of a scripted Jenkinsfile. ![]() ![]() Pipelines are coded as Jenkinsfiles, and the end-to-end pipeline script is written in Groovy, and require some programming knowledge. Traditional Jenkins pipelines are scripted, meaning they prescribe the exact order of steps that need to happen in the pipeline. Like other code, team members can version and review it. This textual approach is the core of the pipeline-as-code method that treats the CD pipeline as an integral part of the application code. Developers build pipelines as code using Domain-Specific Language (DSL).Įach Jenkins pipeline has a definition written in a text-based Jenkinsfile, which development teams can commit to their source control repository. Jenkins Pipelines offers an extensible toolset to model delivery pipelines of varying complexity. The pipeline involves building software using repeatable, reliable steps and pushing the build through various testing and deployment stages. Each software change a developer commits in source control passes through a set of automated processes before being released to production. Jenkins Pipeline is a feature of the Jenkins build server, deployed as a plugin, that lets you implement continuous delivery (CD) pipelines on the Jenkins automation server.Ĭontinuous delivery pipelines are automated sequences of processes to deliver software from version control to customers and end-users. ![]()
