Introduction

This tutorial is going to explain how to setup a local Kubernetes cluster and minimal helm setup to run and deploy SDC (but can be extended to several/all ONAP components) on a single host.

...

Install/remove Microk8s with appropriate version
Install/remove Helm with appropriate version
Tweak Microk8s
Download oom repo
Install the needed Helm plugins
Install ChartMuseum as a local helm repo
Install docker (now needed to build oom charts)
Build all oom charts and store them in the chart repo
Tweak oom override file to fine tune deployment based on your VM capacity and component needs
Deploy/Undeploy charts
Enable local UI access
Full Deployment Override on a single VM
Run testsuites

1) Install/Upgrade Microk8s with appropriate version

...

don't forget to create the namespace again before deploying again (helm won't complain if it is not there, but you'll end up with an empty cluster after if finishes)

Note : you could also reset the K8S cluster by using the microk8s feature : microk8s reset

but that's a more drastic approach, you would need to reinstall the addons, dump again the config for kubectl etc.... this can be useful if you get weird behavior though.

10) Enable UI access

Once all pods are running and all jobs are completed,

...

You can then access the portal UI by opening your browser to :
https://portal.api.simpledemo.onap.org:30225/ONAPPORTAL/login.htm
user/pass is cs0008/demo123456!

Note : Since SDC (and other UIs) are embedded into the portal UI frame, you browser may complain about trusting its certificate, to work around this issue, open the SDC UI directly first (to get your browser to accept the certificate), once done you should be able to open the SDC UI through the portal. To do so, open another tab of your browser to :

...

You should now be able to use SDC :

11) Full Deployment Override on a single VM

Below is a full blown override file used to run mostly all Honolulu components, this was tested working on Windriver Lab on a VM with 12VCpu and 128G Ram

If you want to use SO / Robot - you need to fill in proper properties in the override, this depends on your openstack instance / tenant

12) Run testsuites

If you have deployed the robot pod, you can perform some tests using the provided scripts in the oom repo

go to the oom/kubernetes/robot folder and run ete-k8s.sh to see the available test suites

Code Block
cd ~/oom/kubernetes/robot ./ete-k8s.sh

to run a specific test suite, just provide the namespace and the testsuite tag, below is testing distribution with SDC (beware that some tests require the availability of several components to succeed)

Code Block
cd ~/oom/kubernetes/robot ./ete-k8s.sh onap healthdist

the script will contact the robot pod within the cluster and execute the tests (may take a while)

Code Block
