Custom Legacy Engine Images

Known custom legacy engine images issues.

• Cloudera Data Science Workbench only supports customized engines that are based on the Cloudera Data Science Workbench base image.
• The contents of certain pre-existing standard directories such as /home/cdsw, /tmp, /opt/cloudera, and so on, cannot be modified while creating customized engines. This means any files saved in these directories will not be accessible from sessions that are running on customized engines.

  Workaround: Create a new custom directory in the Dockerfile used to create the customized engine, and save your files to that directory. Or, create a new custom directory on all the Cloudera Data Science Workbench gateway hosts and save your files to those directories. Then, mount this directory to the custom engine.
