Steps needed

Move metadata.json to home dir as a dot file

cp metadata.json ~/.metadata.json

# ETCD_ALL_ENDPOINTS=` etcdctl3 --write-out=fields   member list | awk '/ClientURL/{printf "%s%s",sep,$3; sep=","}'`
# etcdctl3 --endpoints=$ETCD_ALL_ENDPOINTS  endpoint status  --write-out=table

Capture a snapshot:

# etcdctl3 snapshot save /tmp/snapshot.db
