# We are caching the etcd tar file in GCS for reliability and speed.  To
# update this to a new version, do the following:
# 2. Download tar file:
#    curl -LO https://github.com/coreos/etcd/releases/download/<ver>/etcd-<ver>-linux-amd64.tar.gz
# 3. Upload to GCS (the cache control makes :
#    gsutil cp <tar> gs://kubernetes-release/etcd/<tar>
# 4. Make it world readable:
#    gsutil -m acl ch -R -g all:R gs://kubernetes-release/etcd/
# 5. Get a hash of the tar:
#    shasum <tar>
# 6. Update this file with new tar version and new hash
