The kubernetes plug-in for Jenkins works well for us, and as the checkout/clone happens in the pod you don’t have the workspace bind mount problem. We are using docker-in-docker at the moment but looking at buildah. We do parallel windows container builds as well.

Jenkins is a bit like Perl IMO: there are ways to use it that avoid the majority of its sharp edges (eg putting logic in bash and just call bash, avoid groovy) if you know the perils that lurk.
