20180616 this page is deprecated - use Cloud Native Deployment

This page details the Rancher RI installation independent of the deployment target (Openstack, AWS, Azure, GCD, Bare-metal, VMware)

see ONAP on Kubernetes#HardwareRequirements

Pre-requisite

The supported versions are as follows:

ONAP Release	Rancher	Kubernetes	Helm	Kubectl	Docker
Amsterdam	1.6.10	1.7.7	2.3.0	1.7.7	1.12.x
Beijing	1.6.14	1.8.10	2.8.2	1.8.10	17.03-ce

Rancher 1.6 Installation

The following is for amsterdam or master branches

Scenario: installing Rancher on clean Ubuntu 16.04 128g VM (single collocated server/host)

Note: amsterdam will require a different onap-parameters.yaml

Cloud Native Deployment#UndercloudInstall-Rancher/Kubernetes/Helm/Docker

wget https://git.onap.org/logging-analytics/plain/deploy/rancher/oom_rancher_setup.sh

clone continuous deployment script - until it is merged

wget https://git.onap.org/logging-analytics/plain/deploy/cd.sh
chmod 777 cd.sh
wget https://jira.onap.org/secure/attachment/ID/aaiapisimpledemoopenecomporg.cer
wget https://jira.onap.org/secure/attachment/1ID/onap-parameters.yaml
wget https://jira.onap.org/secure/attachment/ID/aai-cloud-region-put.json
./cd.sh -b master -n onap 
# wait about 25-120 min depending on the speed of your network pulling docker images

Config

Rancher Host IP or FQDN

When running the oom_rancher_setup.sh script or manually installing rancher - which IP/FQDN to use

OOM-715 - Getting issue details... STATUS

You can also edit your /etc/hosts with a hostname linked to an ip and use this name as the server - I do this for Azure.

If you cannot ping your ip then rancher will not be able to either.

do an ifconfig and pick the non-docker ip there - I have also used the 172 docker ip in public facing subnets to work around the lockdown of the 10250 port in public for crypto miners - but in a private subnet you can use the real IP.

for example

obrienbiometrics:logging-analytics michaelobrien$ dig beijing.onap.cloud

# i could use 172.17.0.1 only for a single collocated host
# but 10.0.0.4 is the correct IP (my public facing subnet)
# In my case I use -b beijing.onap.cloud
# but in all other cases I could use the hostname
ubuntu@a-ons-auto-beijing:~$ sudo cat /etc/hosts
127.0.0.1 a-ons-auto-beijing

Experimental Installation

Rancher 2.0

see https://gerrit.onap.org/r/#/c/32037/1/install/rancher/oom_rancher2_setup.sh

./oom_rancher2_setup.sh -s amsterdam.onap.info

Run above script on a clean Ubuntu 16.04 VM (you may need to set your hostname in /etc/hosts)

The cluster will be created and registered for you.

Login to port 80 and wait for the cluster to be green - then hit the kubectl button, copy paste the contents to ~/.kube/config

A pods may be setup to log to a volume which can be inspected outside of a container. If you cannot connect to the container you could inspect the backing volume instead. This is how you find the backing directory for a pod which is using a volume which is an empty directory type, the log files can be found on the kubernetes node hosting the pod. More details can be found here https://kubernetes.io/docs/concepts/storage/volumes/#emptydir

here is an example of finding SDNC logs on a VM hosting a kubernetes node.

#find the sdnc pod name and which kubernetes node its running on.
kubectl -n onap-sdnc get all -o wide
#describe the pod to see the empty dir volume names and the pod uid
kubectl -n onap-sdnc describe po/sdnc-5b5b7bf89c-97qkx
#ssh to the VM hosting the kubernetes node if you are not alredy on the vm
ssh root@vm-host
#search the /var/lib/kubelet/pods/ directory for the log file
sudo find /var/lib/kubelet/pods/ | grep sdnc-logs
#The result is path that has the format /var/lib/kubelet/pods/<pod-uid>/volumes/kubernetes.io~empty-dir/<volume-name>

http://<your_dns_name>:30209/logs/demo/InitDistribution/report.html

for example after a

oom/kubernetes/robot$./demo-k8s.sh distribute

find your path to the logs by using for example

root@ip-172-31-57-55:/dockerdata-nfs/onap/robot# kubectl --namespace onap-robot exec -it robot-4251390084-lmdbb bash

root@robot-4251390084-lmdbb:/# ls /var/opt/OpenECOMP_ETE/html/logs/demo/InitD

InitDemo/ InitDistribution/

path is

http://<your_dns_name>:30209/logs/demo/InitDemo/log.html#s1-s1-s1-s1-t1

SSH into ONAP containers

Normally I would via https://kubernetes.io/docs/tasks/debug-application-cluster/get-shell-running-container/

Get the pod name via

kubectl get pods --all-namespaces -o wide

bash into the pod via

kubectl -n onap-mso exec -it  mso-1648770403-8hwcf /bin/bash

Push Files to Pods

Trying to get an authorization file into the robot pod

root@obriensystemskub0:~/oom/kubernetes/oneclick# kubectl cp authorization onap-robot/robot-44708506-nhm0n:/home/ubuntu

above works?
root@obriensystemskub0:~/oom/kubernetes/oneclick# kubectl cp authorization onap-robot/robot-44708506-nhm0n:/etc/lighttpd/authorization
tar: authorization: Cannot open: File exists
tar: Exiting with failure status due to previous errors

Redeploying Code war/jar in a docker container

see building the docker image - use your own local repo or a repo on dockerhub - modify the values.yaml and delete/create your pod to switch images

Docker DevOps#DockerBuild

Turn on Debugging

Running ONAP Portal UI Operations

Running ONAP using the vnc-portal

see (Optional) Tutorial: Onboarding and Distributing a Vendor Software Product (VSP)

or run the vnc-portal container to access ONAP using the traditional port mappings. See the following recorded video by Mike Elliot of the OOM team for a audio-visual reference

https://wiki.onap.org/download/attachments/13598723/zoom_0.mp4?version=1&modificationDate=1502986268000&api=v2

Check for the vnc-portal port via (it is always 30211)

obrienbiometrics:onap michaelobrien$ ssh ubuntu@dev.onap.info
ubuntu@ip-172-31-93-122:~$ sudo su -
root@ip-172-31-93-122:~# kubectl get services --all-namespaces -o wide
NAMESPACE NAME CLUSTER-IP EXTERNAL-IP PORT(S) AGE SELECTOR
onap-portal vnc-portal 10.43.78.204 <nodes> 6080:30211/TCP,5900:30212/TCP 4d app=vnc-portal

launch the vnc-portal in a browser

http://dev.onap.info:30211/

password is "password"

Open firefox inside the VNC vm - launch portal normally

http://portal.api.simpledemo.onap.org:8989/ONAPPORTAL/login.htm

For login details to get into ONAPportal, see Tutorial: Accessing the ONAP Portal

(20170906) Before running SDC - fix the /etc/hosts (thanks Yogini for catching this) - edit your /etc/hosts as follows

(change sdc.ui to sdc.api)

OOM-282 - vnc-portal requires /etc/hosts url fix for SDC sdc.ui should be sdc.api CLOSED

before	after	notes

login and run SDC
