no matches for etcd.database.coreos.com

Hello,

In my local kubernetes cluster i am trying to start an etcd cluster but keep getting the following errors when running "kubectl create -f etcd-cluster.yml":

error: unable to recognize "etcd-cluster.yml": no matches for etcd.database.coreos.com/, Kind=EtcdCluster

The content of the etcd-cluster.yml file is:

apiVersion: "etcd.database.coreos.com/v1beta2"

kind: "EtcdCluster"

metadata:

  name: "example-etcd-cluster"

spec:

  size: 3

  version: "3.1.8"

I am running kubernetes 1.8.    I ran the deploy and that works.  My deploy file is:

apiVersion: extensions/v1beta1

kind: Deployment

metadata:

  name: etcd-operator

spec:

  replicas: 1

  template:

    metadata:

      labels:

        name: etcd-operator

    spec:

      containers:

      - name: etcd-operator

        image: quay.io/coreos/etcd-operator:v0.7.0

        command:

        - etcd-operator

        env:

        - name: MY_POD_NAMESPACE

          valueFrom:

            fieldRef:

              fieldPath: metadata.namespace

        - name: MY_POD_NAME

          valueFrom:

            fieldRef:

              fieldPath: metadata.name

Any suggestions of what could be wrong?

Thanks

Have you checked the logs of the etcd-operator?

The etcd-operator indicated that the user "system:serviceaccount:default:default" does not have the permission to get the endpoints.  After setting the rbac (running the "etcd-operator/example/rbac/create_role.sh") i was able to get the cluster working.  

Thanks.
