These Blueprints are almost identical to the Docker container Blueprints used by DACE R1 and Heat based R2 deployment, except that they are using the k8splugin instead of dockerplugin. The k8splugin is a major contribution of DCAE R2. It is a Cloudify Manager plugin that is capable of expanding a Docker container node definition into a Kubernetes deployment definition, with enhancements such as replica scaling, ONAP logging sidecar, MSB registration, etc. The additional DCAE components launched into ONAP deployment are: + * deploy/dep-config-binding-service; * deploy/dep-dcae-tca-analytics; * deploy/dep-dcae-ves-collector; @@ -90,6 +97,7 @@ Deployment time configuration of DCAE components are defined in several places. * Helm command line supplied values supersedes values defined in any values.yaml files.
