DevOps Project

This is the devops project and will contain all automation related to CI Architecture.

Folder Structure

• resources - Jenkins Library Resources (External libraries may load adjunct files from a resources/ directory using the libraryResource step)
• vars - Jenkins Libarary Scripts (Only entire pipelines can be defined in shared libraries as of this time. This can only be done in vars/*.groovy, and only in a call method. Only one Declarative Pipeline can be executed in a single build, and if you attempt to execute a second one, your build will fail as a result.)
• training - Include some groovy templates to implementing ci/cd flow with Groovy script.

What you'll learn

• Understand the basics of the Jenkins architecture.
• Understand the concept of the Job DSL Plugin on Jenkins and its features.
• Understand with Shared Libraries and Plug-ins
• Implement CICD Pipelines With Jenkins Groovy script
• Understand the basic scenario CICD flow (Build -> Run Testing -> Build Images -> Sonar analysis -> Quality Gateway -> Push Images -> Deploy)
