UAI Images

NOTE: UAS and UAI are deprecated in CSM 1.5.2 and will be removed in CSM 1.6

There are three kinds of UAI images used by UAS:

  • A pre-packaged Broker UAI image provided with the UAS
  • A pre-packaged basic End-User UAI Image provided with the UAS
  • Custom End-User UAI images created on site, usually based on compute node contents

UAS provides two stock UAI images when installed. The first is a standard End-User UAI Image that has the necessary software installed in it to support a basic Linux distribution login experience. This image is provided for the purpose of sanity testing the UAS installation and as a simple starting point for administrative experimentation with UAS and UAIs.

The second image is a Broker UAI image. Broker UAIs are a special type of UAIs used in the “broker based” operation model. Broker UAIs present a single SSH endpoint that responds to each SSH connection by locating or creating a suitable End-User UAI and redirecting the SSH session to that End-User UAI.

A site may provide any number of Custom End-User UAI Images as needed to support various use cases and workflows.
