Introducing zetcd
A big use case of this that we are thinking about is enabling people to use the etcd Operator[1], which makes it simple to run etcd clusters on Kubernetes, to back their ZooKeeper applications.The neat thing about the etcd Operator is you can define a cluster and the etcd Operator takes care of normal operations by using the Kubernetes API.  apiVersion: "etcd.coreos.com/v1beta1"
  kind: "Cluster"
  metadata:
    name: "example-etcd-cluster"
  spec:
    size: 5
    version: "3.1.8"

Pretty neat!Anyways, the zetcd project is still super young but would love more folks to try it out. As the post says folks have already tried using Kafka, Mesos, and others.[1] https://coreos.com/blog/introducing-the-etcd-operator.html
