...
Steps to create a Kubernetes cluster
Follow the below steps 1 - 4
...
to create a Kubernetes cluster
...
Step 5 onwards are needed for getting the Kubernetes Host IP so that user can login to Kubernetes Host and ONAP using OOM can be deployed.
...
Step-1 - https://
...
MGMT_IP_ADDRESS/LOGIN
Step-2 Create the Cloud Provider before creating a kubernetes cluster
...
Before you deploy a Kubernetes cluster, you must create the cloud provider. Cloud provides can be SDDC or OpenStack. Select the option as appropriate.
Here, with VIO with Kubernetes, we select 'OpenStack' as cloud provider
...
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)

6.1 - Download the kubectl using below command
...
sudo mv ./kubectl /usr/local/bin/kubectl
Step-7 Verifying that kubernetes kubectl config is good good
7.1 - On Kubernetes cluster
root@localhost:
...
~# kubectl cluster-info
Kubernetes master is running at .... Heapster is running at.... KubeDNS is running
...
Step 8 Installing Helm
...
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 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-10 Verifying Helm
10.1 - Type the below command
helm help
10.2 - Helm version .
