How to create CoreOS cluster on Google Compute Engine with kube-up?

How should I create a Kubernetes cluster of CoreOS instances on Google Compute Engine with kube-up? I have tried the following, but kube-up times out on cluster validation and I cannot SSH into the created instances (keep getting asked for password):

export KUBE_OS_DISTRIBUTION=coreos
export KUBE_GCE_ZONE=europe-west1-d
export KUBE_GCE_MASTER_IMAGE=coreos-beta-991-2-0-v20160326
export KUBE_GCE_MASTER_PROJECT=coreos-cloud
./cluster/kube-up.sh

could you try this?

export BUILD_PYTHON_IMAGE=true
export KUBE_OS_DISTRIBUTION=coreos
export KUBE_GCE_MASTER_PROJECT=coreos-cloud
export KUBE_GCE_MASTER_IMAGE=coreos-beta-991-2-0-v20160326

make quick-release
cluster/kube-up.sh

Note that BUILD_PYTHON_IMAGE=true needs to be set before make quick-release, it's because coreos master doesn't have python, which is necessary for using the salt.

Ok, a few things

1) to get coreos kube-up working you need more things set

what I use KUBE_OS_DISTRIBUTION=coreos KUBE_ENABLE_CLUSTER_MONITORING=none KUBE_ENABLE_NODE_LOGGING=false KUBE_GCE_INSTANCE_PREFIX=${USER} KUBE_GCE_MASTER_IMAGE=coreos-alpha-960-0-0-v20160217 KUBE_GCE_MASTER_PROJECT=coreos-cloud KUBE_GCE_NETWORK=${USER} KUBE_GCE_NODE_IMAGE=coreos-alpha-960-0-0-v20160217 KUBE_GCE_NODE_PROJECT=coreos-cloud KUBE_GCE_ZONE=us-east1-b KUBE_SKIP_UPDATE=y

2) it seems newer versions of coreos aren't getting ssh keys setup corrcetly in GCE. i.e. you can ssh into the core account (but that will only happen if you have KUBE_OS_DISTRIBUTION=coreos setup correctly, but gcloud ssh wont work, with the version of coreos noted above gcloud ssh will also work
