Lesson 6: Setting up the build and deployment jobs in Jenkins

You can learn about setting up the build and deployment jobs in Jenkins.

About this task

To set up a build and deployment jobs in Jenkins, you must create and configure the following jobs in Jenkins to automate the various stages for the pipeline:

Build_Input: Job for building the application.
Deploy_DEV: Job for deploying the application to the DEV environment.
Deploy_QA: Job for deploying the application to the QA environment.
Deploy_PROD: Job for deploying the application to the PROD environment.
