key	OOM-1

Quickstart

http://rancher.com/docs/rancher/v1.5/en/kubernetes/

https://kubernetes.io/docs/tasks/tools/install-kubectl/

https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux_atomic_host/7/html-single/getting_started_with_kubernetes/

Architecture

Use minikube or bare metal - https://kubernetes.io/docs/setup/pick-right-solution/

Clone

Install the latest version of the OOM (ONAP Operations Manager) project repo - specifically the ONAP on Kubernetes work just uploaded June 2017

...

git clone ssh://michaelobrien@gerrit.onap.org:29418/oom

cd oom/kubernetes/oneclick

Start a service

In this case robot - to check your Kubernetes installation.

[root@obrien-mbp oneclick]# ./createAll.bash -n onap -a robot

********** Creating up ONAP: robot

Creating namespaces **********
namespace "onap-robot" created

Creating services **********
service "robot" created

********** Creating deployments for robot **********

Robot....
deployment "robot" created
**** Done ****[root@obrien-mbp oneclick]# kubectl cluster-info
Kubernetes master is running at http://localhost:8080

To further debug and diagnose cluster problems, use 'kubectl cluster-info dump'.

Kubernetes Rest api
