I am currently working on an OpenShift (=~ Kubernetes) project with a pod containing nginx. Originally, I installed the web server using the OpenShift Catalog. Then a DevOps suggested that I create a pipeline in Jenkins which would build (?) nginx. How do you build a non-Java project with Jenkins? Do I need to build nginx (make, make install, ...), in my case? Can't I just set up Jenkins to retrieve, say, a Docker file containing nginx from a repository?
