Very Quick Start Fails #341

Open alex-treebeard opened 3 years ago

alex-treebeard commented 3 years ago

Description:

I'm new to operators, but it seems the Very Quick Start setup guide is missing the CRD definition installation?

Steps to reproduce:

  1.     ➜ kubectl apply -f http://bit.ly/sparkop
    serviceaccount/spark-operator created
    Warning: rbac.authorization.k8s.io/v1beta1 ClusterRoleBinding is deprecated in v1.17+, unavailable in v1.22+; use rbac.authorization.k8s.io/v1 ClusterRoleBinding
    clusterrolebinding.rbac.authorization.k8s.io/spark-operator-edit-resources created
    deployment.apps/spark-operator created
  2.     ➜ cat <<EOF | kubectl apply -f -
    apiVersion: v1
    kind: SparkCluster
    metadata:
      name: my-cluster
    spec:
      worker:
        instances: "2"
    EOF
    error: unable to recognize "STDIN": no matches for kind "SparkCluster" in version "v1"

Operator creates the CRDs during its startup, so there is no need to create them. It looks like there is a typo in the readme. It the apiVersion should be radanalytics.io/v1 as in here https://github.com/radanalyticsio/spark-operator/blob/master/examples/cluster.yaml
