Spark-on-k8s-operator: Cannot specify imagePullSecret in minikube

[Corallus-Caninus]

Hey, first time posting.. ever (please assist me with formatting etc.)

I have set up RBAC and can successfully run the py-pi.py example script. When trying to add a secret for pulling from our company's private repository I get the following error:

E0701 21:01:51.616935 9 reflector.go:125] github.com/GoogleCloudPlatform/spark-on-k8s-operator/pkg/client/informers/externalversions/factory.go:119: Failed to list *v1beta1.SparkApplication: v1beta1.SparkApplicationList.Items: []v1beta1.SparkApplication: v1beta1.SparkApplication.Spec: v1beta1.SparkApplicationSpec.ImagePullSecrets: []string: ReadString: expects " or n, but found {, error found in #10 byte of ...|ecrets":[{"name":"gi|..., bigger context ...|","imagePullPolicy":"Always","imagePullSecrets":[{"name":"gitlab"}],"initContainerImage":"gcr.io/spa|...

It looks to me that the json format in minikube's secret isn't cooperating with the SparkApplication yaml.

the aforementioned secret works when deploying kind Deployment, replica set and pod.

I have changed the container Image to a gcr target but it triggers the same error with our private repository, it seems to not get passed the secret parsing.

Thank you

syntax differs from kubernetes spec.containers.imagePullSecrets - name: value pair is just value.
wrong:
-- name: mySecret

correct:
-- mySecret
