This page captures all information and steps that are needed for deploying ONAP via OOM using /on VIO 4.0 Kubernetes .
Assumption .This pages assumes that user have VIO4.0 with kubernetes deployed with cloud provider as openstack successfully .
a. prerequisite -
a.1 User should have the BlueShift Mgmt IP Address , user name and password ready to be able to create Kubernetes cluster .
a.2 K8S Master and K8S Node instances should have Flavor attached as per the requirement below .
| vCPU | 48 |
| RAM | 96GB |
| Storage | 256GB |
Step1 to Step3 are needed for creating a kubernetes cluster .
TOComplete 20171205 - Step 4 onwards are needed for getting the Kubernetes Host IP so that user can login to Kubernetes Host and ONAP using OOM can be deployed ..
TODO 20171205 - steps that needs to be done prior to git Clone of OOM .

2 - Create the kubernetes cluster by clicking + NEW
3.1 . click NEXT
3.2 . Select an Infrastructure Provider for creating the kubernetes cluster .
Before you deploy a Kubernetes cluster, you must have created the cloud provider . VMware Integrated OpenStack with Kubernetes uses the cloud provider to create the infrastructure required to deploy all your Kubernetes clusters. VMware currently supports 2 options for infrastructure provider .VMware SDDC (vSphere + NSX + VSAN) or VIO (VMware Integrated OpenStack) .
When choosing the type of provider to create, consider the following:
- With an existing VMware Integrated OpenStack deployment, you can create an OpenStack provider.
- Without an existing VMware Integrated OpenStack deployment, you can create an SDDC provider Im.
provider name can be custom name given by user where as provider Type has to be opestack or sddc .
3.3 . Select a Node Profile . Default Node Profile can be modified to have the desired flavor for the kubernetes cluster .
3.4 . Provide the Input for the Cluster as indicated below
ClusterName :TestCluster
Number of master nodes : 1
Number of worker nodes : 1
DNS servers : <IP Address of DNS Server i.e 10.112.64.1 >
Cluster Type : Esxclusive /Shared
Node Types A Kubernetes cluster is comprised of two types of nodes. Each node in the VMware Integrated OpenStack with Kubernetes is a VM.
Master Nodes A master node provides the Kubernetes API service, scheduler, replicator, and so on. It manages the worker nodes. A cluster with a single master node is valid but has no redundancy.
Worker Nodes A worker node hosts your containers. A cluster with a single worker node is valid but has no redundancy.
Cluster Types VMware Integrated OpenStack with Kubernetes supports two types of clusters.
Exclusive Cluster In an exclusive cluster, multi-tenancy is not supported. Any authorized Kubernetes user using the Kubernetes CLI of APIs has namespace management privileges.
The exclusive cluster provides a familiar environment for developers who deploy Kubernetes themselves.
Shared Cluster In a shared cluster, multi-tenancy is supported and enforced by the Kubernetes namespace. Only a VMware Integrated OpenStack with Kubernetes administrator using the VMware Integrated OpenStack with Kubernetes interface or CLI has namespace management privileges. The shared cluster is an environment where the administrator can manage resource isolation among users.
3.5 create the user and Group
3.6 click on finish
4. Verifying the VIO Kubernetes Cluster . If everything in step 3.1 to step 3.6 has been done successfully .The Summary information for the cluster will be filled as given in the example below .
5. How to get Kubernetes Host IP Address and login to Kubernetes Host .
5.1 Login Via Putty to KUBNERTES_IP_ADDRESS . user name and password is same as used in step1 .
5.2 once logged into Putty session use the command "vkube login --insecure" . use the user name and password same as in step1 .
5.3 get the list of clusters using command "vkube cluster list --insecure" . make a note of cluster Id in the output of the command
5.4 get the cluster node details using command "vkube cluster show <cluster Id > --insecure " .make note of worker ip address .Worker IP Address KUBERNETES_HOST_IP.
5.5 login to app-api docker using docker exec it app-api bash
5.6 once inside the app-api docker go to /var/lib/vrc/terraform/<cluserId>
5.7 ssh -i private.key -F ssh.bastion.conf ubuntu@KUBERNETES_HOST_IP_ADDRESS .
5.8 once inside KUBERNETES_HOST_IP_ADDRESS
6. Installing Kubectl to manage Kubernetes cluster using kubectl
TBC20171207 6.1 download the kubectl using below command on
curl -LO https://storage.googleapis.com/kubernetes-release/release/v1.7.0/bin/linux/amd64/kubectl
6.2 Make the kubectl binary executable.
chmod +x ./kubectMove the binary in to your PATH.6.3 Move the kubectl to PATH
sudo mv ./kubectl /usr/local/bin/kubectl
7. Verifying Kubectl installation
