   I've got the same error : 
   ```logs
   2020/03/27 07:43:16 [emerg] 1#1: host not found in resolver "kube-dns.kube-system" in /etc/nginx/nginx.conf:42
   nginx: [emerg] host not found in resolver "kube-dns.kube-system" in /etc/nginx/nginx.conf:42
   ```
   
   Here my installation :
   
   - os: debian 10
   - Kubernetes v1.17.4
   
   As root ($USER is the user I want to set docker group and not env var)
   ```sh
   curl -sSL https://get.docker.com/ | sudo bash
   sudo usermod -aG docker $USER
   curl -s https://packages.cloud.google.com/apt/doc/apt-key.gpg | apt-key add -
   add-apt-repository "deb https://apt.kubernetes.io/ kubernetes-xenial main"
   apt-get update
   apt-get install -y kubectl kubeadm kubelet
   apt-mark hold kubelet kubeadm kubectl
   echo "1" > /proc/sys/net/ipv4/ip_forward
   swapoff -a
   sed -i -r 's/^(\S+\s+swap\s+.*)$/#\1/' /etc/fstab
   kubeadm init --pod-network-cidr=192.168.0.0/16
   ```
   
   As $USER
   ```
   mkdir -p /home/$USER/.kube
   cp /etc/kubernetes/admin.conf /home/$USER/.kube/config
   chown $USER:$USER /home/$USER/.kube -R
   kubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/v2.0.0-rc6/aio/deploy/recommended.yaml
   kubectl apply -f https://docs.projectcalico.org/manifests/calico.yaml
   
   git clone https://github.com/apache/openwhisk-deploy-kube.git
   cd git clone openwhisk-deploy-kube
   
   echo "whisk:
     ingress:
       type: NodePort
       apiHostName: 192.168.65.3
       apiHostPort: 31001
   nginx:
     httpsNodePort: 31001
   k8s:
     dns: kube-dns.kube-system" > custom_values.yml
   
   kubectl create namespace openwhisk
   helm install openwhisk ./helm/openwhisk --namespace=openwhisk -f ./custom_values.yml
   ```
   
   Here the output of `kubectl get services -n kube-system` taht I use to set the value of `k8s.dns` : 
   ```logs
   NAME       TYPE        CLUSTER-IP   EXTERNAL-IP   PORT(S)                  AGE
   kube-dns   ClusterIP   10.96.0.10   <none>        53/UDP,53/TCP,9153/TCP   42h
   ```
   
   I think the helm installation wasn't set the cluster role binding. Without that role, the openwhisk pods can't call other namespaces pods.
   
   I'm wrong ?
