+### hyperkube
+
+`hyperkube` is an all-in-one binary for the Kubernetes server components
+`hyperkube` is built for multiple architectures and _the image is pushed automatically on every release._
+
+#### How to release by hand
+
+```console
+# First, build the binaries
+$ build/run.sh make cross
+
+# Build for linux/amd64 (default)
+# export REGISTRY=$HOST/$ORG to switch from staging-k8s.gcr.io
+
+$ make push VERSION={target_version} ARCH=amd64
+# ---> staging-k8s.gcr.io/hyperkube-amd64:VERSION
+# ---> staging-k8s.gcr.io/hyperkube:VERSION (image with backwards-compatible naming)
+
+$ make push VERSION={target_version} ARCH=arm
+# ---> staging-k8s.gcr.io/hyperkube-arm:VERSION
+
+$ make push VERSION={target_version} ARCH=arm64
+# ---> staging-k8s.gcr.io/hyperkube-arm64:VERSION
+
+$ make push VERSION={target_version} ARCH=ppc64le
+# ---> staging-k8s.gcr.io/hyperkube-ppc64le:VERSION
+
+$ make push VERSION={target_version} ARCH=s390x
+# ---> staging-k8s.gcr.io/hyperkube-s390x:VERSION
+```
+
+If you don't want to push the images, run `make` or `make build` instead
