To use DataLake, you need to have at least one of these systems ready. Once DataLake is deployed, you can configure Topic and storage in the DataLake Admin UI.
Deployment Steps
Preconfiguration of tiller and helm
DL-handler consists of two pods- the feeder and admin UI. It can be deployed by using cloudify Helm plug-in. Since the tiller IP address and port should be exposed and accessed by Helm, some additional configuration steps are needed. the detailed pre-configuration steps can be found in the Cloudify Helm Plugin wiki page.
Next, the cloudify input file of datalake should be placed into bootstrap pod. The input file can be found in ONAP git repository. Once you clone the repository, the blueprint file could be copied to the DCAE bootstrap pod through the command line.
