Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.
Is there any way to exclude new nodes to a K3S cluster from being longhorn storage nodes?
1 project | reddit.com/r/rancher | 3 Dec 2021
You can use node selector rules to force Longhorn to use some nodes for storage. You can also add taints to create dedicated storage nodes. Please see the GitHub link listed below. https://github.com/longhorn/longhorn/issues/1633
Separating storage and worker nodes with Longorn
1 project | reddit.com/r/rancher | 25 Nov 2021
In Longhorn GUI the volume shows as Detached. It would attach if I do is manually but that makes no impact to the Pod. I've seen people having similar issues in 2614 and have tried with create-default-disk-on-labeled-nodes but that does not seem to work the way I would like to. If I deploy without nodeSelector and disable scheduling on worker nodes it works fine.

Longhorn is exactly what you're looking for. It's easy to set up and backs up to NFS.
Rancher Desktop, a Docker Desktop Replacement
14 projects | news.ycombinator.com | 11 Oct 2021
More than performance, I am worried about security. They don't seem to have considered it at all when building it: https://github.com/longhorn/longhorn/issues/1983
Probably not a good recommendation until this hole is plugged.14 projects | news.ycombinator.com | 11 Oct 2021
They've also got Longhorn, a distributed container-attached storage solution that's very simple to understand and easy to deploy. Performance is another thing but that's the same with all of the general networked storage solutions (Ceph included).
Rancher's got a well deserved good impression in my mind, though early on I avoided it since it seemed like they were building a walled garden.
Should We Replace Docker Desktop With Rancher Desktop?
6 projects | reddit.com/r/kubernetes | 11 Oct 2021
All of their projects have been fully open, monetized with enterprise support. They straight up fully donated their storage project to the CNCF. They've been good stewards of all the tools so far with ones like k3s greatly benefitting the community. And have put a decent amount of effort into putting resources supporting issues on even non-paid issues on the GitHub projects.
ZFS and Ceph
2 projects | reddit.com/r/zfs | 22 Sep 2021
Also just in case the above wasn't enough I'm probably actually going to run Longhorn because it's just SO much easier than Ceph to manage and gives me the availability for a ~40% perf loss AFAIK.
Those running Kubernetes, what is in your core stack? And what "gem" can you not live without?
8 projects | reddit.com/r/homelab | 19 Sep 2021
Longhorn for Kubernetes storage. It lets me automatically provision PersistentVolumes and snapshot/back them up to S3. I've read that other things such as Ceph and Rook are more stable and I've definitely been bit by some non-critical bugs, but the project is very active and bugs are squashed quickly (though they don't release very frequently). This is the gem I can't live without, being able to snapshot, backup and restore things like my Plex volume has saved me at least a dozen times already.
Selfhosted storage recommendation
1 project | reddit.com/r/selfhosted | 18 Sep 2021
Another consideration is using something like https://longhorn.io/, it's a bit like ceph, and supports mirroring over two nodes
Achieve Maintenance Free Setup

If you want to make your container maintenance easier though, check out Watchtower. It's a container that will update all your container images whenever there's new ones, and rebuild your containers with their existing configuration, so it's pretty seamless.
Command to update all container images and relaunch?
2 projects | reddit.com/r/docker | 27 Nov 2021
I don't believe there is an easy way to do this through docker but something like https://github.com/containrrr/watchtower might interest you.2 projects | reddit.com/r/docker | 27 Nov 2021
You might want to look into https://containrrr.dev/watchtower/. Available as a container.
How do you all harden your exposed services?
1 project | reddit.com/r/selfhosted | 21 Nov 2021
Also, I think it is a good idea to set watch tower to update docker image to latest automatically. https://github.com/containrrr/watchtower It make sure you got security fix from matrix developers.

I found this but I worry that I am messing with other docker images that the user might have => https://containrrr.dev/watchtower/ Cron is also my preferred solution but then I have to explain cron to the user (and cron is diffrent on every plattform )

PS : Watchtower is a service (running in his own container) that can monitor/notify/auto update your images and restart those containers. Very usefull ;-)
