Azure Private DNS - flag parsing error: unknown long flag

[rnkhouse]

I am using the below config file to add private DNS in Azure Private DNS. I am using istio gateway on AKS.

external_dns.yaml

    apiVersion: v1
    kind: ServiceAccount
    metadata:
    name: external-dns
    ---
    apiVersion: rbac.authorization.k8s.io/v1beta1
    kind: ClusterRole
    metadata:

    resources: ["services"]
    verbs: ["get","watch","list"]
    - apiGroups: [""]

    verbs: ["get","watch","list"]
    - apiGroups: ["extensions"] 
    resources: ["ingresses"]

            - name: AZURE_CLIENT_SECRET
            value: "AZURE_CLIENT_SECRET_VALUE"

Error:

Also I am getting this error:

Hi @rnkhouse

azure-private-dns isn't in a released version yet. It will be available in >=v0.5.18.

You can use gcr.io/k8s-staging-external-dns/external-dns:v20200110-v0.5.17-153-ga1ff7d75 in the meantime.
