OnDemand 3.1 release

Hi. We’ve just made the Open OnDemand 3.1.0 release available. We’ve had it installed at OSC for just about a week and have not found any issues, though CSC has found one when using ssh_allow in batch connect applications.

Highlights for this release include:

To be clear, the bug CSC found was pertains to this configuration ssh_allow.


3.1.1 has been released with the bugfix for centers that disable shell connections with ssh_allow.

3.1.4 is generally available with some bug fixes and a few security related fixes.


  • The path_selector now responds to labels and can be hidden in in 3467.
  • Pinned app icons are now centered correctly in 3374.


  • ood_core now sends heartbeats to noVNC connections to keep them alive in 3467.
  • Batch connect jobs now serialize completed_at attributes in 3467.


  • The files app now uses ActionController::Live to support streaming large files in 3467 preventing out of memory exceptions.
  • The regular expression for mime types has been updated in 3482.

3.1.7 is now generally available with some bug fixes and at least 1 security related fix. Note that the security fix is around leaking secret environment variables so it’s very important to update.


  • Logo Images no longer take 100% width.
  • Dynamic batch connect forms now accept fields with numbers like data-hide-gpus-num-v100
  • host_based_profiles now correctly route to the correct server alias


  • ood_portal.yml now has http_redirect_host to specify the host to redirect to when redirecting from http to https (to support `host_based_profiles).
  • Passenger and Ngxinx have been updated to 6.0.20 and 1.24.0 respectively.
  • Nginx stage commands for cleaning PUNs use ps instead of lsof for performance in containerized environments.


  • The dashboard and job composer now sanitize the environment before submitting jobs. This prevents leaking sensitive environment variables like SECRET_KEY_BASE to the job.
