helmfile: Helmfile doesn't work when no internet access

Hi there,

we are using helmfile to deploy our stack to kubernetes on premise. I have downloaded charts offline and constructed:

context: kubernetes-admin@kubernetes                # kube-context (--kube-context)

releases:

  # Prometheus deployment
  - name: prom-helmf-ns-monitoring              # name of this release
    namespace: monitoring                       # target namespace
    chart: /opt/kubernetes/stable/prometheus                    # the chart being installed to create this release, referenced by `repository/chart` syntax
    values: ["values/values_prometheus_ns_monitoring.yaml"]
    set:                                        # values (--set)
      - name: rbac.create
        value: true
  # Grafana deployment
  - name: graf-helmf-ns-monitoring              # name of this release
    namespace: monitoring                       # target namespace
    chart: /opt/kubernetes/stable/grafana
    values: ["values/values_grafana_ns_monitoring.yaml"]

  # Controller pod (Nginx)
  - name: controller-pod-nginx                  # name of this release
    namespace: ingress-nginx                    # target namespace
    chart: /opt/kubernetes/stable/nginx-ingress                 # the chart being installed to create this release, referenced by `repository/chart` syntax
    values: ["values/values_nginx_ns_ingress-nginx.yaml"]
    set:                                        # values (--set)
      - name: rbac.create
        value: true

Everything is happening offline My kubernetes cluster is up and running

kubectl create serviceaccount --namespace kube-system tiller
kubectl create clusterrolebinding tiller-cluster-rule --clusterrole=cluster-admin --serviceaccount=kube-system:tiller
# kubectl patch deploy --namespace kube-system tiller-deploy -p '{"spec":{"template":{"spec":{"serviceAccount":"tiller"}}}}'
helm init   --service-account tiller --skip-refresh

When I run helmfile:

 helmfile -f monitoring_deployment.yaml sync
exec: helm repo update --kube-context kubernetes-admin@kubernetes
