Docker Block Device

The Cloudera Data Science Workbench installer will format and mount Docker on each gateway host.

Make sure there is no important data stored on these devices. Do not mount or format the Docker Block Devices before installing Cloudera Data Science Workbench.

Every Cloudera Data Science Workbench gateway host must have one or more block devices with at least 1 TB dedicated to storage of Docker images. The Docker block devices store the Cloudera Data Science Workbench Docker images including the Python, R, and Scala engines. Each engine image can occupy 15GB.
