Hello,
We're evaluating OpenShift v3, which uses Docker. The manual recommends
using NFS v4 for storage. I would much prefer to use Gluster's native
client instead of NFS, mainly because the Gluster client is so easy to
use. One of our Redhat SEs says it is probably fine to use Gluster
instead of NFS v4 for now until OpenShift gets formal support for
Gluster in OpenShift 3.1. I asked him why Gluster wasn't initially
supported and he said it probably came down to not having enough time to
test thoroughly before OSE's release.
Hi Ryan - I checked internally with the corresponding Red Hat teams and
got a similar response. Lack of time is the core reason for going ahead
with NFS. You can follow up with your Red Hat representatives to ensure
that support for fuse lands in a subsequent OSE release.
Does anyone have any experience with running Docker images with Gluster
using the Gluster client? Is it possible that Redhat's recommendation is
based on the performance of NFS v4 vs Gluster?
No performance numbers have been gathered with fuse client in OSE and
hence the question of comparison does not arise. What
applications/workloads do you intend running in OSE?
I can't seem to find
anything that says one is faster than the other. Has anyone used Gluster
with Docker (which powers OpenShift)?
There have been various write ups on the web about using Gluster and
Docker. I would be very interested if someone on this list has direct
experience with this combination.
Thanks,
Vijay
