A lot of posts describe how to do this, but are fairly outdated, and do not mention the last supported K8s version. Here’s a tried and tested way to do so via Helm. This has been tested on GKE, with the Kubernetes master version\u00a01.9.7-gke.6:<\/p>\n

    \n
  1. \n
      \n
    1. Create the service account for Tiller – the Helm server\n
      $ kubectl create serviceaccount --namespace kube-system tiller<\/pre>\n<\/li>\n
    2. Create the cluster role\n
      $ kubectl create clusterrolebinding tiller-cluster-rule --clusterrole=cluster-admin --serviceaccount=kibe-system:tiller<\/pre>\n<\/li>\n
    3. Apply the RBAC role\n
        \n
      1. Create tiller.yml with the following content\n
        kind: ClusterRoleBinding\r\napiVersion: rbac.authorization.k8s.io\/v1beta1\r\nmetadata:\r\n  name: tiller-clusterrolebinding\r\nsubjects:\r\n- kind: ServiceAccount\r\n  name: tiller\r\n  namespace: kube-system\r\nroleRef:\r\n  kind: ClusterRole\r\n  name: cluster-admin\r\n  apiGroup: \"\"<\/pre>\n<\/li>\n
      2. Apply this\n
        $ kubectl create -f tiller.yaml\r\n\r\n<\/pre>\n<\/li>\n<\/ol>\n<\/li>\n
      3. Initialise Helm\n
        helm init --service-account tiller --upgrade<\/pre>\n<\/li>\n
      4. Wait until the tiller-deploy service is running\n
        $ while ! kubectl get pod -n kube-system | grep tiller-deploy | grep Running &> \/dev\/null; do\r\n  echo \"Waiting for the tiller-deploy pod to be ready...\"\r\n  sleep 1\r\ndone<\/pre>\n<\/li>\n
      5. Install the Nginx Ingress Controller\n
        helm install --name nginx-ingress stable\/nginx-ingress --set rbac.create=true<\/pre>\n<\/li>\n
      6. Have fun!<\/li>\n<\/ol>\n<\/li>\n<\/ol>\n
