Pre-Requisites
Before running the chart, create a namespace and a registry secret to hold the docker credentials needed to download the Oracle Database Docker image from Docker Store. Please note that you need to accept the License Agreement with your accounte on Docker Store before being able to download the image.
Create a namespace (if you don't want to use the default one)
