A note about image formats

There are currently two different image formats:

  • standard: A standard disk image is one that can be loaded on either a bare metal node or a XEN virtual machine. The images are interchangeable between the two; if you take a snapshot of a bare metal machine, that disk image can then be loaded on a XEN VM. The reverse is also true. The is the default image format used across all clusters.
  • docker: Some clusters support docker containers as virtual nodes. Images in the docker format can be used as disk images in docker containers. Detailed information on using docker containers and images for them, can be found in the manual
