For Eclipse projects the CI/CD infrastructure is provided by Eclipse Foundation. With more and more new projects coming up Foundation needs to optimize its existing infrastructure.
One way to solve this problem is to have private cloud deployed on the hardware, run the tasks in their own containers using cutom docker images. Foundation deployed Openshift as its private cloud platform and created Jenkins instances to use Openshift based containers. This resulted in migration of exiting CI/CD infrastructure to newer Openshift based Jenkins instances.
