(on each host) add to your /etc/hosts to point your ip to your hostname (add your hostname to the end). Add entries for all other hosts in your cluster.

sudo vi /etc/hosts
<your-ip> <your-hostname>

clone oom (scp your onap_rsa private key first - or clone anon - Ideally you get a full gerrit account and join the community)

see ssh/http/http access links below

https://gerrit.onap.org/r/#/admin/projects/oom

anonymous http
git clone http://gerrit.onap.org/r/oom
or using your key
git clone ssh://michaelobrien@gerrit.onap.org:29418/oom

or use https (substitute your user/pass)

git clone https://michaelnnnn:uHaBPMvR47nnnnnnnnRR3Keer6vatjKpf5A@gerrit.onap.org/r/oom

(on each host (server and client(s) which may be the same machine)) Install only the 1.12.x (currently 1.12.6) version of Docker (the only version that works with Kubernetes in Rancher 1.6)

Install Docker

curl https://releases.rancher.com/install-docker/1.12.sh | sh

(on the master only) Install rancher (use 8880 instead of 8080) - note there may be issues with the dns pod in Rancher after a reboot or when running clustered hosts - a clean system will be OK -

docker run -d --restart=unless-stopped -p 8880:8080 rancher/server

In Rancher UI - dont use (http://127.0.0.1:8880) - use the real IP address - so the client configs are populated correctly with callbacks

You must deactivate the default CATTLE environment - by adding a KUBERNETES environment - and Deactivating the older default CATTLE one - your added hosts will attach to the default

Pre pull docker images the first time you install onap. Currently the pre-pull will take 10-35 min depending on the throttling, what you have already pulled and load on nexus3.onap.org:10001. Pre pulling the images will allow the entire ONAP to start in 3-8 min instead of up to 3 hours.

You must deactivate the default CATTLE environment - by adding a KUBERNETES environment - and Deactivating the older default CATTLE one - your added hosts will attach to the default

• • Default → Manage Environments
  • Select "Add Environment" button
  • Give the Environment a name and description, then select Kubernetes as the Environment Template
  • Hit the "Create" button. This will create the environment and bring you back to the Manage Environments view
  • At the far right column of the Default Environment row,
  • Default → Manage Environments
  • Select "Add Environment" button
  • Give the Environment a name and description, then select Kubernetes as the Environment Template
  • Hit the "Create" button. This will create the environment and bring you back to the Manage Environments view
  • At the far right column of the Default Environment row, left-click the menu ( looks like 3 stacked dots ), and select Deactivate. This will make your new Kubernetes environment the new default.

Register your host(s) - run following on each host (including the master if you are collocating the master/host on a single machine/vm)

For each host, In Rancher > Infrastructure > Hosts. Select "Add Host"

The first time you add a host - you will be presented with a screen containing the routable IP - hit save only on a routable IP.

Enter IP of host: (if you launched racher with 127.0.0.1/localhost - otherwise keep it empty - it will autopopulate the registration with the real IP)

Copy command to register host with Rancher,

Execute command on host, for example:

% docker run --rm --privileged -v /var/run/docker.sock:/var/run/docker.sock -v /var/lib/rancher:/var/lib/rancher rancher/agent:v1.2.2 http://192.168.163.131:8880/v1/scripts/BBD465D9B24E94F5FBFD:1483142400000:IDaNFrug38QsjZcu6rXh8TwqA4

wait for kubernetes menu to populate with CLI

Install Kubectl

The following will install kubectl on a linux host. Once configured, this client tool will provide management of a Kubernetes cluster.

curl -LO https://storage.googleapis.com/kubernetes-release/release/$(curl -s https://storage.googleapis.com/kubernetes-release/release/stable.txt)/bin/linux/amd64/kubectl
chmod +x ./kubectl
mv ./kubectl /usr/local/bin/kubectl
mkdir ~/.kube
vi ~/.kube/config

Paste kubectl config from Rancher (you will see the CLI menu in Rancher / Kubernetes after the k8s pods are up on your host)

Click on "Generate Config" to get your content to add into .kube/config

Verify that Kubernetes config is good

root@obrien-kube11-1:~# 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....

Install Helm

The following will install Helm (use 2.3.0 not current 2.6.0) on a linux host. Helm is used by OOM for package and configuration management.

Prerequisite: Install Kubectl

wget http://storage.googleapis.com/kubernetes-helm/helm-v2.3.0-linux-amd64.tar.gz
tar -zxvf helm-v2.3.0-linux-amd64.tar.gz
mv linux-amd64/helm /usr/local/bin/helm
# Test Helm
helm help

Undercloud done - move to ONAP Installation

Wait until all the hosts show green in rancher, then run the createConfig/createAll scripts that wraps all the kubectl commands - off of oom/kubernetes/config and oom/kubernetes/oneclick

whereever you pulled oom

Source the setenv.bash script in /oom/kubernetes/oneclick/ - will set your helm list of components to start/delete

source setenv.bash

run the one time config pod - which mounts the volume /dockerdata/ contained in the pod config-init. This mount is required for all other ONAP pods to function.

Note: the pod will stop after NFS creation - this is normal.

% cd oom/kubernetes/config
# edit or copy the config for MSO data
vi onap-parameters.yaml
# or
cp onap-parameters-sample.yaml onap-parameters.yaml 
# run the config pod creation
% ./createConfig.sh -n onap 

**** Creating configuration for ONAP instance: onap
namespace "onap" created
pod "config-init" created
**** Done ****

Wait for the config-init pod is gone before trying to bring up a component or all of ONAP - around 60 sec (up to 10 min) - see https://wiki.onap.org/display/DW/ONAP+on+Kubernetes#ONAPonKubernetes-Waitingforconfig-initcontainertofinish-20sec

root@ip-172-31-93-122:~/oom_20170908/oom/kubernetes/config# kubectl get pods --all-namespaces -a

onap          config                                 0/1       Completed   0          1m

Note: When using the -a option the config container will show up with the status, however when not used with the -a flag, it will not be present

Cluster Configuration (optional - do not use if your server/client are co-located)

A mount is better.

Try to run you host and client on a single VM (a 64g one) - if not you can run rancher and several clients across several machines/VMs. The /dockerdata-nfs share must be replicated across the cluster using a mount or by copying the directory to the other servers from the one the "config" pod actually runs. To verify this check your / root fs on each node.

# in this case a 4 node cluster of 16g vms - the config node is on the 4th
root@kube16-3:~# ls /
bin  boot  dev  dockerdata-nfs  etc  home  initrd.img  lib  lib64  lost+found  media  mnt  opt  proc  root  run  sbin  snap  srv  sys  tmp  usr  var  vmlinuz
root@kube16-3:~# scp -r /dockerdata-nfs/ root@kube160.onap.info:~
root@kube16-3:~# scp -r /dockerdata-nfs/ root@kube161.onap.info:~
root@kube16-3:~# scp -r /dockerdata-nfs/ root@kube162.onap.info:~     

Running ONAP

Pre pull docker images the first time you install onap. Currently the pre-pull will take 10-35 min depending on the throttling, what you have already pulled and load on nexus3.onap.org:10001. Pre pulling the images will allow the entire ONAP to start in 3-8 min instead of up to 3 hours.
