![]() ![]() Once a Jenkinsfile is created, it is committed to a repository in the version control system that’s hosting the source code. Usually, a Jenkinsfile is created by a developer or system administrator with a detailed understanding of how to deploy the particular component or application. Integrating CI/CD and GitOps with JenkinsfilesĪ Jenkinsfile is a text file, written in the Groovy programming language, that defines each step in a Jenkins job. The process was laborious, particularly if the job in question was large and contained many details.įortunately, the new Jenkins Pipeline job feature addresses these drawbacks head-on. And, if developers or sysadmins wanted to move a job to another Jenkins server, they had to get into the file system of the Jenkins server and copy particular directories to other target Jenkins servers. If developers wanted to update a particular job, they had to go to the server’s Jenkins Dashboard and manually implement the update. Deployments ( aka jobs) were not easy to update or transfer among servers. Moreover, each job was specific to the particular Jenkins server. The developer defined the tasks to run and when to run them, and Jenkins did the rest.Įarly releases of Jenkins required developers to define their deployment processes manually, using the Jenkins Dashboard. From its first release, Jenkins allowed companies to standardize their deployment process: Once a job was configured on the Jenkins server, that job could run repeatedly in the same manner according to its configuration. Jenkins is an open source tool for managing deployment processes, which can range from a single task-such as running a unit test against source code-to a complex deployment process embodying many tasks. Then, I’ll guide you through how to use a Jenkinsfile to create deployments that combine CI/CD and GitOps. We'll start with a brief refresher of what Jenkins is and how it applies to both CI/CD and GitOps. Developers and release engineers can use Jenkinsfiles to combine the practices of CI/CD and GitOps into a unified deployment process. ![]() One of the most transformative features added to Jenkins is the ability to run Jenkins Pipeline jobs driven by an automation script stored in a Jenkinsfile. Jenkins has been around for years and has undergone numerous revisions, adding features all along the way. Jenkins is one of the most popular tools used for CI/CD. Fortunately, there are many tools that lessen the burden. In this process, developers and release engineers create scripts that have all the instructions needed to test the code in a source code repository before putting it into a production environment. Coupled with GitOps, CI/CD allows developers to release high-quality software almost as soon as they commit code to a repository such as GitHub.Īutomation is a key factor for implementing effective CI/CD. CI/CD, or continuous integration and continuous delivery, is an essential part of the modern software development life cycle. ![]()
