Jenkins
Jenkins is an open source continuous integration/continuous delivery and deployment (CI/CD) automation software DevOps tool written in the Java programming language.
It is used to implement CI/CD workflows, called pipelines (by configuration files called Jenkinsfile or web ui ).
The need for Jenkins becomes especially acute when deploying to a microservices architecture. Since one of the goals of microservices is to frequently update applications and services, the ability to do so is relevant and significat.
Pipelines: jenkinsfile
Jenkins pipelines can be defined using a text file called JenkinsFile. You can implement pipeline as code using JenkinsFile, and this can be defined by using a domain specific language (DSL).
With JenkinsFile, you can write the steps needed for running a Jenkins pipeline in Groovy: a (declarative and/or scripting) multi-faceted language for the Java platform very similar to yaml (declarative o more declarative).
