The OOM (ONAP Operation Manager) project has pushed Kubernetes based deployment code to the oom repository. This page details on getting ONAP running on Kubernetes for various environments.
Undercloud Installation
We need a kubernetes installation with the proper architecture components running. This architecture can be provided by vendors like Redhat or Rancher
https://kubernetes.io/docs/concepts/overview/components/
Ubuntu 16.04 Install Session
Install Rancher
http://rancher.com/docs/rancher/v1.5/en/quick-start-guide/
http://rancher.com/docs/rancher/v1.6/en/installing-rancher/installing-server/#single-container
Install a docker version that Rancher and Kubernetes support which is currently 1.12.3
http://rancher.com/docs/rancher/v1.5/en/hosts/#supported-docker-versions
...
curl https://releases.rancher.com/install-docker/1.12.sh | sh
docker run -d --restart=unless-stopped -p 8880:8080 rancher/server:stable
Verify your Rancher admin console is up on the external port you configured above
Wait for the docker container to finish DB startup
Having issues registering a combined single VM (controller + host) - moving on to using 2 VM's
http://rancher.com/docs/rancher/v1.6/en/hosts/
ONAP Installation
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
Provision
Manually
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'.
The official documentation for installation of ONAP with OOM / Kubernetes is located in Read the Docs:
- OOM User Guide — onap master documentation
- OOM Quick Start Guide — onap master documentation)
- OOM Cloud Setup Guide — onap master documentation
