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.

Collect logs and Kubernetes resources when Pod is in crashloopbackoff state
The ConfigMap referenced by EventBasedAddOn instance contains all resources that will be deployed in each cluster where a Pod in crashing state is found. In this case:

Projectsveltos: Manage Kubernetes addons in multiple clusters
https://github.com/projectsveltos/sveltosctl#display-outcome...
But I was still not happy. Main reason, users still had to go and manage cluster labels. I wanted clusters' labels to change as cluster runtime state was changing. So I can express my intent and then forget about it.
So I introduced a second concept in Sveltos. Classifier CRD (https://github.com/projectsveltos/demos/blob/main/classifier...) which allows users to classify clusters based on cluster runtime state (currently kubernetes version and/or resources deployed, but I am working on adding more).
Doing so I can easily now say:
-
Upgrading Kubernetes addons automatically as cluster runtime state changes
1) I wanted a controller running in the management cluster, so I can express my intent and as clusters come and go or change their runtime state, controller can make sure my intent is applied. For instance, combing Classifier and ClusterProfile I can say things like, in any cluster running kubernetes version v1.24.x install calico v3.23 and in any cluster running kubernetes version v1.25.x install calico v3.24. as clusters are created/upgraded, sveltos makes sure my intent is deployed (https://github.com/projectsveltos/demos/blob/main/classifier/classifier.gif)

Deploy Kubernetes add ons in ClusterAPI powered cluster

Simplifying Kubernetes Cluster Management with Claudie and Sveltos
Claudie simplifies the process of programmatically establishing Kubernetes clusters across multiple cloud vendors and on-premises datacenters. It provides a centralized management interface for provisioning and managing clusters, eliminating the need for manual configuration and maintenance. Claudie's capabilities include:
-
Best cross cloud managed Kubernetes that also supports bare metal?

Claudie is a managed Kubernetes for Hetzner, now coming with Cluster Autoscaler
There's also Hetzner bootstrapping information specifically here: https://github.com/berops/claudie/blob/master/docs/input-manifest/providers/hetzner.md
What are some alternatives?
