Running DSS Design, Automation and Deployer nodes in a container is not supported. Only realtime (API) nodes can be executed in containers. DSS provides tools to create such images, please refer to the documentation here for more information.
Although Dataiku provides pre-canned images for all the major cloud provides, it is not mandatory to use such images for installing Design nodes. Those images are provided for exploratory and quick start deployments, and come with pre-made decisions such installed packages, security, DSS install location etc. that might not fit your needs. You can start a VM and install DSS on your own, following our documentation.
