7.2 - On client from Where Kubernetes cluster can be managed Remotely  

root@localhost:~# kubectl  version

Client Version: version.Info{Major:"1", Minor:"7", GitVersion:"v1.7.0", GitCommit:"d3ada0119e776222f11ec7945e6d860061339aad", GitTreeState:"clean", BuildDate:"2017-06-29T23:15:59Z", GoVersion:"go1.8.3",

Compiler:"gc", Platform:"linux/amd64"}

Server Version: version.Info{Major:"1", Minor:"7+", GitVersion:"v1.7.7-rancher1", GitCommit:"a1ea37c6f6d21f315a07631b17b9537881e1986a", GitTreeState:"clean", BuildDate:"2017-10-02T21:33:08Z",GoVersion:"go1.8.3" Compiler:"gc", Platform:"linux/amd64"}

Step-8 Verifying that kube config is good 

8.1 - On Kubernetes cluster  

root@localhost:~# cat  ~/.kube/config 

apiVersion: v1

kind: Config
clusters:
- cluster:
api-version: v1
insecure-skip-tls-verify: true
server: "<SERVER_IP_ADDRESS:8080/r/projects/CLUSTER_NAME/kubernetes:SERVER_PORT_NUMBER"
name: "(CLUSTER_NAME)"
contexts: 
- context:
cluster: "(CLUSTER_NAME)"
user: "(CLUSTER_NAME)"
name: "(CLUSTER_NAME)"
current-context: "(CLUSTER_NAME)"
users:
- name: "(CLUSTER_NAME/USER_NAME)"
user:
token: "<SECURITY_TOKEN>"

8.2 - On client from where Kubernetes cluster can be managed Remotely  

root@localhost:~# cat  ~/.kube/config 

current-context: default-context

apiVersion: v1
clusters:
- cluster:
api-version: v1
server: https://SERVER_IP_ADDRESS:SERVER_PORT_NUMBER/
insecure-skip-tls-verify: true
name: CLUSTER_NAME

contexts:
- context:
cluster: CLUSTER_NAME 
namespace: default
user: user1
name: default-context
users:
- name: user1
user:
username: "<USERNAME>"
password: "<PASSWORD"
kind: Config
preferences:
colors: true

Step-9 Installing Helm 

9.1 - Download the helm  using below command  

wget http://storage.googleapis.com/kubernetes-helm/helm-v2.3.0-linux-amd64.tar.gz

89.2 - Untar the  fileDownload the helm  using below command  

tar -zxvf helm-v2.3.0-linux-amd64.tar.gz

89.3 - Move the helm to /usr/local/bin

sudo mv linux-amd64/helm /usr/local/bin/helm

Step 9 Verifying Helm  -10 Verifying Helm  

10.1 - Type the below command 

helm help

10.2 - Helm version .
