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.

Schedule on Least Utilized Node
maybe descheduler can help? https://github.com/kubernetes-sigs/descheduler
-
I have 3 nodes. One of the nodes suddenly went down. How do I make the pods spread evenly to the other nodes?
Surprised this wasn't suggested yet, you can also use a software like the k8s Descheduler that executes periodically to rebalance your workloads across the existing nodes.

Ask HN: Who else is working/on call over Christmas?
This is something a (now former) colleague of mine pointed out: that the kubernetes descheduler can enforce a maximum lifetime[0] that sort of forces continual reboots. So if your system cannot tolerate running for a long time continously, this is one method to gracefully restart long running pods.

K8S Operators - How do you reserve on every node resources for system daemonsets ?
no it does not... thats why tools like https://github.com/kubernetes-sigs/descheduler exist..

Database corruption
I am trying to run sonarr inside my k3s cluster. Since I have multiple nodes, in order to keep data persistant I have been using a NAS and the Kubernetes NFS external provisioner as my Storage Class.

Longhorn alternatives
Depends on how much resiliency you need . Something like https://github.com/kubernetes-sigs/nfs-subdir-external-provisioner works well for a lab or non-prod cluster. You could even use something like this in prod if you have access to highly reliably NFS mounts.

Recommendations for k8s storage solution
I first installed a NFS Server via this helm chart: https://github.com/kubernetes-sigs/nfs-subdir-external-provisioner Eventually I deployed Longhorn cause I needed expandable volumes, which the first repo doesn't support. I guess for best performance you should go for a ceph cluster, but I'm not an expert.
-
Move to K8s for hosting at home?
I used the NFS provisioner for persistent volumes until I got the Ceph side up and running. I created a share on my NAS specifically for k8s. It worked very well and had the bonus of being just a regular file system that you could browse/edit easily (just place files in or edit config). I would agree with not moving plex into k8s. I right now just have a barebones 1 control 2 worker setup using k3s.
-
K8s - Self hosted PaaS?
However, is it too difficult to create new pods/deployments etc on your own? I find it super easy to just create a PVC (via https://github.com/kubernetes-sigs/nfs-subdir-external-provisioner ) and create a MySQL pod in a new namespace for every micro service I create.
-
Unsure how NFS Persistent Volumes work, please help!
This is what you need https://github.com/kubernetes-sigs/nfs-subdir-external-provisioner Point it to a folder and it will create subfolders for each PVC.
