Step-2 Create the Cloud Provider before creating a kubernetes cluster
...
Step-5 How to get Kubernetes Host host IP Address and login to Kubernetes Host host .
5.1 - Login via console window to BLUESHIFT_MGMT_IP_ADDRESS . user name and password is same as used in step1 .
...
5.8 - Once inside KUBERNETES_HOST_IP_ADDRESS (to be reviewed)
Step-6 Installing kubectl to manage Kubernetes cluster
6.1 - Download the kubectl using below command
...
sudo mv ./kubectl /usr/local/bin/kubectl
Step-7 Verifying that kubectl config is good good
7.1 on Kubernetes Cluster 7.1 - On Kubernetes cluster
root@localhost:~# kubectl cluster-info
Kubernetes master is running at ....
Heapster is running at....
KubeDNS is running at ....
kubernetes-dashboard is running at ...
monitoring-grafana is running at ....
monitoring-influxdb is running at ...
tiller-deploy is running at....7.2 on Client 7.2 - On client from Where Kubernetes cluster can be managed Remotely root@localhost
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"

Step-8 Verifying that kube config is good
8.1 on Kubernetes Cluster
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 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

users:
...
- name: user1
...
user:
...
username: "<USERNAME>"
...

Step-9 Installing Helm
99.1 - Download the helm using below command

99.2 - Download the helm using below command
...
sudo mv linux-amd64/helm /usr/local/bin/helm
Step-10 Verifying Helm
10.1 type 10.1 - Type the below command helm
helm help
10.2 helm 10.2 - Helm version .
