SUMMARY:Anchor: Diskless Cluster Provisioning Using Container Tools
DESCRIPTION:State of the Practice Talk\n\nAnchor: Diskless Cluster Provisi
 oning Using Container Tools\n\nVoss\n\nLarge scale compute clusters are of
 ten managed without  local disks to ease configuration management across s
 everal hundred nodes. This diskless management frequently relies on a coll
 ection of in-house scripts designed to build client compute images. By lev
 eraging container building tools matured by the tech community we can redu
 ce internal technical debt while allowing cluster installations to be more
  flexible and resilient. Deploying container images to compute clusters, h
 owever, remains an unsolved problem.  To this end we present Anchor, an ex
 tensible initrd module designed to boot clusters from an immutable squashF
 S image with a read-write overlay. The code referenced in this paper is av
 ailable at https://github.com/olcf/anchor.\n\nTag: Best Practices, Contain
 ers, System Management\n\nRegistration Category: Tech Program Reg Pass
