perfSONAR User Q&A and Other Discussion

[Zachary Newell <>]

FWIW, I’ve been experimenting with LXD\LXC containers for perfsonar deployments, and it has worked quite well for us. LXD has been in Ubuntu for a while and is now a part of Debian 12.  Part of the reason I chose LXD\LXC is because Cisco has adopted LXC, and I’d like to see if we can run a testpoint on a router.

Can you expand a bit on the Docker option? Previously (on 4.4.6) my understanding was that the Docker option was only for “one-off” tests meant to be stood up and torn down without much in the way of central management or interacting with an archiver. Has that changed?

 

Some of our early experiments with Docker were like that, but what we publish now encompasses the entire perfSONAR testpoint distribution.  (I forget what release started that, but it was 4.4.0 at the latest.)  You can configure that to become part of a mesh and send results to an archive as you would on bare metal.

 

What we do at Internet2 is dedicate CPU cores and RAM to the container and  bind the container to a dedicated 100 Gb/s interface on the host using macvlan.  I’ve attached a script containing the commands we use to launch our containers with any internal stuff redacted.  The script manages two containers, so you can skip the duplicates.  Depending on your local arrangements, you may want to derive a container from the one perfSONAR distributes that has site-specific customizations and run that.
