I tried to build kubernetes with tag v1.20.15, however, I see following error:

To retry manually, run:

docker build -t kube-build:build-1b391dbecf-5-v1.15.15-legacy-1 --pull=false --build-arg=KUBE_BUILD_IMAGE_CROSS_TAG=v1.15.15-legacy-1 --build-arg=KUBE_BASE_IMAGE_REGISTRY=<http://k8s.gcr.io/build-image|k8s.gcr.io/build-image> /Users/yongxiang.gao/source/kubernetes/_output/images/kube-build:build-1b391dbecf-5-v1.15.15-legacy-1

How to fix it?

1. that’s an ancient version of Kubernetes 2. I would probably see if anyone on the Kubernetes slack can help you; this is the Rancher users slack and you probably aren’t going to find many folks trying to build vanilla Kubernetes from source.

Good point, thanks a lot.
