Groovy script in Jenkins

In this article I will host website on kubernetes using Groovy script in Jenkins from docker image. Whole process will be fully automated from creating docker image to exposing website to the client. Hence client can access this website from the webserver created.

Jenkinsfile for building and pushing image automatically.

Job1: To build and push image to the docker hub.

Create a job ,you must have pipeline plugin installed. Here when you build this job Jenkins will search for Jenkinsfile in Github URL. Then it will build and push the code automatically to the docker hub.
