ingress_grpc.enabled=true helm install error

[cyxinda]

If ingress_grpc.enabled=true,some error would happend,like this:

  ingress:
    enabled: true
    ingressClassName: nginx
    hostname: "dgraph.knowdee.com"
    # annotations: {}
    tls: 
    - hosts: 
      - dgraph.knowdee.com
      secretName: dgraph-dgraph-alpha-tls-secret

  ## alpha GRPC ingress resource configuration
  ## This requires an ingress controller to be installed into your k8s cluster
  ingress_grpc:
    enabled: true
    ingressClassName: nginx
    hostname: "grpc-dgraph.knowdee.com"
    annotations: 
      nginx.ingress.kubernetes.io/backend-protocol: GRPC
      nginx.ingress.kubernetes.io/ssl-redirect: "true"
    tls: 
    - hosts: 
      - grpc-dgraph.knowdee.com
      secretName: dgraph-dgraph-alpha-tls-secret

        Helm install failed: error while running post render on files:
        map[string]interface {}(nil): yaml: unmarshal errors:
          line 31: mapping key "apiVersion" already defined at line 2
          line 32: mapping key "kind" already defined at line 3
          line 33: mapping key "metadata" already defined at line 4
          line 41: mapping key "spec" already defined at line 14

it is because there are the extra "-" in the file of dgraph/templates/alpha/ingress.yaml at the line 64. it should remove the symbol "-".

the helm chart version is dgraph/dgraph:0.2.2 .
