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.

...

There are limitations in using this setup, the purpose is to allow for developers to quickly get access to a working environment 'the way their component is supposed to be deployed'

This is not meant for production obviously, and the tweaks that are done to the OOM/K8s setup are most likely going to evolve with further releases.

1) Install/Upgrade Microk8s with appropriate version

...

2) it is not using docker as the container runtime, it's using containerd, it's not an issue, just be aware of that as you won't see containers using classic docker commands

How to remove/install /remove microk8s ?

If you have a previous version of microk8s, you first need to uninstall it (upgrade is possible but it is not recommended between major versions so I recommend to uninstall as it's fast and safe)

...

Code Block
sudo snap install microk8s --classic --channel=1.19/stable

You may need to change your firewall configuration to allow pod to pod communication and pod to internet communication :

Code Block
sudo ufw allow in on cni0 && sudo ufw allow out on cni0 sudo ufw default allow routed

Addons ?

...

18/stable
sudo snap refresh microk8s --classic --channel=1.19/stable

Or (when the master node bug will be fixed on 1.19 kubernetes snap install)

sudo snap install microk8s --classic --channel=1.19/stable

You may need to change your firewall configuration to allow pod to pod communication and pod to internet communication :

Code Block
sudo ufw allow in on cni0 && sudo ufw allow out on cni0 sudo ufw default allow routed

Addons ?

MicroK8s is lightweight but comes with several possible addons, OOM and ONAP requires just a few to be enabled, you can choose to enable more if you want to

...

Storage addon : we will enable the default Host storage class, this allows local volume storage that are used by some pods to exchange folders between containers.

Code Block
sudo microk8s enable dns storage

...

As Helm is self contained, it's pretty straightforward to install/upgrade

I recommend putting helm in local bin folder as a softlink, this way it's easy to switch between versions if you need to

...

, we can also use snap to install the right version

Code Block
sudo snap install helm --classic --channel=3.5/stable

Note: You may encounter some log issues when installing helm with snap

Normally the helm logs are available in "~/.local/share/helm/plugins/deploy/cache/onap/logs", if you notice that the log files are all equal to 0, you can uninstall the helm with snap and reinstall it manually

Code Block
wget https://get.helm.sh/helm-v3.5.4-linux-amd64.tar.gz

Code Block
tar xvfz helm-v3.5.4-linux-amd64.tar.gz

Code Block
sudo mv linux-amd64/helm /usr/local/bin/helm

3) Tweak Microk8s

The below tweaks are not strictly necessary, but they help in making the setup more simple and flexible.

A) Increase the max number of pods & Add priviledged config

As ONAP may deploy a significant amount of pods, we need to inform kubelet to allow more than the basic configuration (as we plan an all in box setup), if you only plan to run a limited number of components, this is not needneeded

to change the max number of pods, we need to add a parameter to the startup line of kubelet.edit

1. Edit the file located at :

Code Block
sudo nano /var/snap/microk8s/current/args/kubelet

...

Code Block
sudo service snap.microk8s.daemon-kubelet restart

B) run a local copy of kubectl

...

2. Edit the file located at :

Code Block
microk8ssudo kubectl describe node

to make things simpler, let's install a local copy of kubectl so we can use it to interact with the kubernetes cluster in a more straightforward way

We need kubectl 1.19 to match the cluster we have installed

Code Block
curl -LO https://storage.googleapis.com/kubernetes-release/release/v1.19.7/bin/linux/amd64/kubectl chmod +x ./kubectl sudo mv ./kubectl /usr/local/bin/kubectl

If you want to use a the same link trick as for helm (see above) this could allow you to switch between kubectl versions if needed

...

nano /var/snap/microk8s/current/args/kube-apiserver

add the following line at the end :

Code Block
--allow-privileged=true

save the file and restart kubelet to apply the change :

Code Block
sudo service snap.microk8s.daemon-apiserver restart

B) run a local copy of kubectl

Microk8s comes bundled with kubectl, you can interact with it by doing:

Code Block
sudo microk8s kubectl describe node

to make things simpler as we will most likely interact a lot with kubectl, let's install a local copy of kubectl so we can use it to interact with the kubernetes cluster in a more straightforward way

We need kubectl 1.19 to match the cluster we have installed, let's again use snap to quickly choose and install the one we need

Code Block
sudo snap install kubectl --classic --channel=1.19/stable

Now we need to provide our local kubectl client with a proper config file so that it can access the cluster, microk8s allows to retrieve the cluster config very easily

Simply create a .kube folder in your home directory and dump the config there

Code Block
cd mkdir .kubecdkube cd .kube sudo microk8s.config > config chmod 700 config

...

4) Download OOM repo

OOM provides a couple of plugins that we need to install for helm, the easiest is to get them straight from the repository.

Since we will also build the charts locally, it's the right time to download a local copy, you'll need to install git if it's not available yet on your machine

the example below pulls the latest version from master, it's probably wiser to select the right version (honolulu branch or a specific review you want to test)

Code Block
cd git clone "https://gerrit.onap.org/r/oom"

5) Install the needed Helm plugins

Onap deployments are using the deploy and undeploy plugins for helm

to install them just run :

Code Block
helm plugin install ./oom/kubernetes/helm/plugins/undeploy/ helm plugin install ./oom/kubernetes/helm/plugins/deploy/

this will copy the plugins into your home directory .helm folder and make them available as helm commands

Another plugin we need is the push plugin, with helm3 there is no more an embedded repo to use.

Code Block
helm plugin install --version v0.9.0 https://github.com/chartmuseum/helm-push.git

Once all plugins are installed, you should see them as available helm commands when doing :

Code Block
helm --help

6) Install the chartmuseum repository

To align with how the previous release were deployed, we will setup a local chart repository.

To do, download the chartmuseum script and run it as a background task

Code Block
curl https://raw.githubusercontent.com/helm/chartmuseum/main/scripts/get-chartmuseum \| bash mkdir ~/chartmuseum chartmuseum --port=8080 --storage="local" --storage-local-rootdir="~/chartstorage" &

you should see the chartmuseum repo starting locally, you can press enter to come back to your terminal

you can now inform helm that a local repo is available for use :

Code Block
helm repo add local http://localhost:8080

Note this is a very basic setup, meaning you'll need to startup your local repo if you shut down your VM or if you exit this terminal, there are other ways to do it, like using a docker compose to ensure 'it's always on'

Also, you can setup a local database for Helm to store it's deployment (more info on Helm website), this is useful if you want to upgrade and undeploy charts, now on this setup which is aimed for developpers, the approach is a clean install and wipe if we need to change something so we won't describe this part here, see last point on how to deploy/undeploy with this setup

7) Install docker

During the processing of the oom helm charts (oom-cert-service component of platform), docker is needed as it is used to create certificates.

Follow the docker install instructions for Ubuntu here : https://docs.docker.com/engine/install/ubuntu/

unless you already have docker, in which case you can skip this part altogether.

Or use snap:

Code Block
sudo snap install docker

8) Build all oom charts and store them in the chart repo

You should be ready to build all helm charts, go into the oom/kubernetes folder and run a full make

Ensure you have "make" installed:

Code Block
sudo apt install make

Then build OOM

Code Block
cd ~/oom/kubernetes make all

You can speed up the make skipping the linting of the charts

Code Block
make all -e SKIP_LINT=TRUE

You'll notice quite a few message popping into your terminal running the chartmuseum, showing that it accepts and store the generated charts, that's normal, if you want, just open another terminal to run the helm commands

Once the build completes, you should be ready to deploy ONAP

9) Tweak oom override file to fine tune deployment based on your VM capacity and component needs

Before deploying, it's good to decide which ONAP components you need and create an override file. The override file will tune your deployment to your specific needs.

We have a few considerations to take on our stand alone VM :

1) CPU/Memory might be limited, so be careful on what you enable / disable. K8S 1.19 now properly enforce CPU and memory requests/limits so it is important to define/override them correctly

2) Timeouts : the more component you enable, the more the liveness probes and readiness probes timeouts may have to be increased, knowing that we will most likely over commit the VM CPU.

First, here is a very basic override file to enable a very small setup with SDC, we will only enable aaf, portal, SDC and cassandra shared, this should work on a laptop with enough ram :

copy the content below to a file called onap-honolulu.yaml

          cpu: 100m
          memory: 500Mi

You'll notice the tweaks to the timeouts and memory settings and limits, this is mostly what you have to adapt depending on your needs

Once the file is ready you can deploy :

1) First you need to ensure that the onap namespace exists (it now must be created prior deployment)

Code Block
kubectl create namespace onap

2) Launch the chart deployment, pay attention to the last parameter, it must point to your override file create above

Code Block
helm deploy onap local/onap --namespace onap -f ~/onap-honolulu.yaml

The deployment can take a while depending on how many charts you've enabled.

You should see all pods starting up and you should be able to see logs using kubectl, dive into containers etc...

How to undeploy and start fresh

The easiest is to use kubectl, you can clean up the cluster in 3 commands :

Code Block
kubectl delete namespace onap kubectl delete pv --all sudo rm -rf /dockerdata-nfs

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 may want to connect to the ONAP UIs locally, to do so you first need to add the following to your /etc/host (adapt the IP address if you use a remote VM)

Code Block

# for myVM ONAP
127.0.0.1 aaf-gui
127.0.0.1 aai.ui.simpledemo.onap.org
127.0.0.1 appc.api.simpledemo.onap.org
127.0.0.1 cds.api.simpledemo.onap.org
127.0.0.1 cdt.api.simpledemo.onap.org

127.0.0.1 sdc.workflow.plugin.simpledemo.onap.org
127.0.0.1 so-monitoring
127.0.0.1 vid.api.simpledemo.onap.org

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 :

https://sdc.api.fe.simpledemo.onap.org:30207/

https://sdc.workflow.plugin.simpledemo.onap.org:30256/

Note : you need to repeat the above for each deployment, as certificates are generated by AAF during startup, certificates will change each time you deploy

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
