Storage Class
In minikube mariadb-galera has problems to deploy because of persistence problems:

Note. Currently, elalto branch of OOM is more tested. I've just noticed that master OOM provides CDS 0.6.3, which is outdated.... When deploying cds or other ONAP components needing mariadb-galera, override "global.persistence.storageClass" with correct storage class.
Deploy CDS

helm upgrade --install dev ./onap --namespace onap \
--set cds.enabled=true \
--set cds.cds-blueprints-processor.dmaapEnabled=false \
--set global.persistence.storageClass=standard |
Deploy CDS with more overrides e.g. different image versions

Normally Helm charts (e.g. image versions) should be kept completely in sync with related software version, but for CDS this has not been the case. This also leads to problems that CDS may not work in the Kubernetes (where is should be run). Developers, please test CDS daily in the Kubernetes and update OOM git repo for Helm charts changes.
