Merged in 0.1.4. Thanks!

I think I had a bug.
At the moment I've got the following error:

Error: release cl-nifi failed: StatefulSet in version "v1beta2" cannot be handled as a StatefulSet: v1beta2.StatefulSet.Spec: v1beta2.StatefulSetSpec.Template: v1.PodTemplateSpec.Spec: v1.PodSpec.InitContainers: []v1.Container: v1.Container.Command: []string: ReadString: expects " or n, but found {, error found in #10 byte of ...|rets:\n",{"name":"re|..., bigger context ...|keeper..."\n sleep 2\ndoneimagePullSecrets:\n",{"name":"regcred"}],"image":"busybox","name":"zooke|...

I think it must be {{- if .Values.image.pullSecret }} instead of {{- if .Values.image.pullSecret -}}
Can you verify this?

@ebcFlagman should be fixed in 0.1.5.
