It is yet not clear which version of Microk8s works for which ONAP release. Successfuly Successfully tested is Microk8s 1.15 for Frankfurt release. E.g. the latest Microk8s version doesnt doesn't work for Frankfurt. Run the following command to install a specific version of Microk8s.

...

Code Block

language	bash
title	Enable add-ons of Microk8s

microk8s enable storage

microk8s enable dns

Microk8s 1.15 comes with helm v2.14.3, ONAP Frankfurt release requires helm v2.16.6, you can use snap to install required helm version:

Code Block

language	bash
title	Install Microk8s

snap install microk8shelm enable dns 
--classic --channel=2.16/stable

The default storage class is required in the Helm deploy command later on, therefore take note of it with the following command.

...

Clone ONAP Helm charts for specific release including submodules

git clone --branch frankfurt --recurse-submodules "https://gerrit.onap.org/r/oom"

Change to kubernetes dir
```
cd oom/kubernetes
```

Initialize Helm and configure Tiller

Code Block

language	bash
title	Configure Tiller

microk8s kubectl -n kube-system create serviceaccount tiller
 
microk8s kubectl create clusterrolebinding tiller-cluster-rule --clusterrole=cluster-admin --serviceaccount=kube-system:tiller
 
microk8s helm init --service-account tiller
 
microk8s kubectl -n kube-system rollout status deploy/tiller-deploy

Start Helm service and initialize local Helm repository
```
make repo

# This will do same as:
```
helm serve &
helm repo add local http://127.0.0.1:8879
Package ONAP Helm charts
```
make
```

...

Code Block

language	bash
title	Deploy CDS

microk8s helm upgrade --install dev ./onap --namespace onap \
--set cds.enabled=true \
--set mariadb-galera.enabled=true \
--set global.masterPassword=random \
--set cds.cds-blueprints-processor.dmaapEnabled=false \
--set global.persistence.storageClass=microk8s-hostpath

...

As end result you should see CDS pods running. Note that "cds-sdc-listener" POD will never get up with this setup because it's dependent on SDC.

Code Block

$ microk8s kubectl -n onap get pod

Ports can be forwarded e.g. to access the CDS-UI from another machine. To forward the CDS-UI Port use the following command.

Code Block
microk8s kubectl port-forward dev-cds-ui-679cbf49fd-hswkd -n onap --address 0.0.0.0 3000:3000

Take care to provide the right pod name and port number. The port of CDS-UI can be displayed by:

Code Block
microk8s kubectl -n onap get pod dev-cds-ui-679cbf49fd-hswkd --template='{{(index (index .spec.containers 0).ports 0).containerPort}}{{"\n"}}'

Afterwards the CDS-UI should be accessable accessible externally.
