-### flannel
-
-This is used mostly for the `docker-multinode` config, but also in other places where flannel runs in a container.
-
-For `amd64`, this image equals to `quay.io/coreos/flannel` to maintain official support.
-For other architectures, `flannel` is cross-compiled. The `debian-iptables` image serves as base image.
-
-#### How to release
-
-```console
-# Build for linux/amd64 (default)
-$ make push ARCH=amd64
-# ---> gcr.io/google_containers/flannel-amd64:TAG
-
-$ make push ARCH=arm
-# ---> gcr.io/google_containers/flannel-arm:TAG
-
-$ make push ARCH=arm64
-# ---> gcr.io/google_containers/flannel-arm64:TAG
-
-$ make push ARCH=ppc64le
-# ---> gcr.io/google_containers/flannel-ppc64le:TAG
-```
-
-If you don't want to push the images, run `make` or `make build` instead
