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:
-
Send Slack Notification when Pod is in crashloopbackoff state
All YAMLs used in this example can be found here

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
So a second concept was introduced in Sveltos: Classifier CRD (https://github.com/projectsveltos/demos/blob/main/classifier/classifier.gif) 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).
k8s_collector
-
Collect logs and Kubernetes resources when Pod is in crashloopbackoff state
A Job containing a Kubernetes collector instance. This job will collect logs and Kubernetes resources and save those in the corresponding volume
What are some alternatives?
addon-controller - Sveltos Kubernetes add-on controller programmatically deploys add-ons and applications in tens of clusters. Support for ClusterAPI powered clusters, Helm charts, kustomize ,YAMLs. Sveltos has built-in support for multi-tenancy.
sveltos-agent - Classify cluster and report back to management cluster. Evaluates cluster health based on custom health checks. Watches for events and reports those to management cluster.
sveltos-manager - Sveltos is tool for managing Kubernetes add-ons in tens of clusters. Support for ClusterAPI powered clusters and helm charts. Sveltos has built-in support for multi-tenancy. [Moved to: https://github.com/projectsveltos/addon-manager]
classifier - Sveltos Classifier dynamically classify a cluster based on run time information (Kubernetes version, deployed resources and more)
kind - Kubernetes IN Docker - local clusters for testing Kubernetes
cluster-api - Home for Cluster API, a subproject of sig-cluster-lifecycle
Kyverno - Kubernetes Native Policy Management
claudie-sveltos-integration - This repository aims to streamline the integration between Claudie and Sveltos. It incorporates a controller that monitors Claudie's Secrets for kubeconfig files of Claudie-managed clusters and automatically creates corresponding SveltosCluster resources.
