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.

Leader Election In Kubernetes
Here an example of coordination api in Go https://github.com/kubernetes-sigs/descheduler/commit/3cbae5e72ba53447a609e6001755ff395e6eeceb https://github.com/kubernetes-sigs/descheduler/commit/0a52af9ab82a52fd8c864a81f4033736f11aab34

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.

It sounds like you are looking for pod anti affinity, good example here: https://github.com/infracloudio/kubernetes-scheduling-examples/blob/master/podAffinity/README.md
