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.

ZFS 2.2.0 (RC): Block Cloning merged
I use it in Kubernetes via https://github.com/openebs/zfs-localpv
The PersistentVolume API is a nice way to divvy up a shared resource across different teams, and using ZFS for that gives us the snapshotting, deduplication, and compression for free. For our workloads, it benchmarked faster than XFS so it was a no-brainer.
- openebs/zfs-localpv: CSI Driver for dynamic provisioning of Persistent Local Volumes for Kubernetes using ZFS.

OpenEBS on MicroK8S on Hetzner
Last few months I experimented more and more with all OpenEBS solutions that fit small Kubernetes cluster, using MicroK8S and Hetzner Cloud for a real experience.
- Openebs ?? Or equivalent

Network Storage on On-Prem Barebones Machine
I would investigate https://openebs.io/ https://portworx.com/ https://longhorn.io/ if you are forced to you can mount ISCSI on the kublet and feed it to one of those solutions. Keep in mind most of the big guys buy some sort of managed solution that you can point a CSI like trident https://netapp-trident.readthedocs.io

Ask HN: What are some fun projects to run on a home K8s cluster?
What are some cool projects to self hosted on a home Raspberry Pi (64 bit) Kubernetes cluster (Helm charts). arm64 support is a must. A lot of projects only build amd64 Docker containers which don't run on my cluster.
I currently run:
- obenebs (provides abstraction for using local k8s worker disks as PVC mounts when running on-prem) -- https://openebs.io/
-
Finally got around to doing that Ceph on ZFS experiment
I didn't set anything actually -- I need to look into whether OpenEBS ZFS LocalPV can facilitate passing ZVOL options (I don't think it can just yet). The only tuning I did on the storage class was the usual ZFS-level options.

My self-hosting infrastructure, fully automated
What do you use to provision Kubernetes persistent volumes on bare metal? I’m looking at open-ebs (https://openebs.io/).
Also, when you bump the image tag in a git commit for a given helm chart, how does that get deployed? Is it automatic, or do you manually run helm upgrade commands?

Building a "complete" cluster locally
Ideas from my kubernetes experience: * Cert-Manager is very popular and almost a must-have if you terminate SSL inside the cluster * Backups using velero * A dashboard/UI is actually very helpful to quickly browse resources, client tools like k9s are fine too * Secret: Management: Bitnami Sealed Secrets is the second big project in that space * I would add Loki to aggregate Logs * Never heard of ory. Usually I see (dex)[https://dexidp.io/] or keycloak used for Authentication * I like to run OpenEBS as in-cluster storage. * Istio isn't compatible with the upcomming ServiceMeshInterface (i think), so the trend seem to go toward Linkerd * Some Operator to deploy your favorite Database, is also a nice learning exercise.

Why OpenEBS 3.0 for Kubernetes and Storage?
OpenEBS CStor (declared stable), has added support for a CSI Driver and also improved customer resources and operators for managing the lifecycle of CStor Pools. This 3.0 version of the CStor includes:
-
32 Node KBN-I/5200 Kubernetes cluster running Debian 10/K8s 1.17/Intel Core i7/8GB RAM each. Used the standoffs and mounted each 8 stack to empty trays. Disks are 64GB USB3 sticks.
It's a little complicated at first but there's also OpenEBS and Longhorn. Longhorn is probably the most easiest to get going with, but I chose rook-ceph because it's very stable.

Looking for a sanity check on a project I'm working on at home, hoping you fine people can help - Raspberry Pi Kubernetes Cluster
- SMB CSI: https://github.com/kubernetes-csi/csi-driver-smb - OpenEBS if you got the hardware for it: https://openebs.io/

Best Open-Source Distributed Parallel Storage Option for an AI/ML Cluster?
Tried OpenEBS? These two have replication HA features. https://github.com/openebs/Mayastor https://github.com/openebs/cstor-operators
What are some alternatives?
longhorn - Cloud-Native distributed storage built on and for Kubernetes
Mayastor - Dynamically provision Stateful Persistent Replicated Cluster-wide Fabric Volumes & Filesystems for Kubernetes that is provisioned from an optimized NVME SPDK backend data storage stack.
democratic-csi - csi storage for container orchestration systems
jiva-operator - Kubernetes Operator for managing Jiva Volumes via custom resource.
lvm-localpv - Dynamically provision Stateful Persistent Node-Local Volumes & Filesystems for Kubernetes that is integrated with a backend LVM2 data storage stack.
openebs - Most popular & widely deployed Open Source Container Native Storage platform for Stateful Persistent Applications on Kubernetes.
k3s - Lightweight Kubernetes
dynamic-nfs-provisioner - Operator for dynamically provisioning an NFS server on any Kubernetes Persistent Volume. Also creates an NFS volume on the dynamically provisioned server for enabling Kubernetes RWX volumes.
rook - Storage Orchestration for Kubernetes
csi-driver-smb - This driver allows Kubernetes to access SMB Server on both Linux and Windows nodes.
