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.

Upgrading Hundreds of Kubernetes Clusters
The last one is mostly an observability stack with Prometheus, Metric server, and Prometheus adapter to have excellent insights into what is happening on the cluster. You can reuse the same stack for autoscaling by repurposing all the data collected for monitoring.

Helm: Is there a way to access templates of a sibling subchart
I'm deploying kube-prometheus-stack along with prometheus-adapter in my monitoring stack for custom metrics.

Deploy prometheus-adapter with kube-prometheus-stack monitoring stack?
I would like to see if anyone deployed prometheus-adapter and kube-prometheus-stack together for monitoring?

Horizontal Pod Autoscale
For us it is saturation of CPU and thread pool. It's implemented by exposing metrics of the thread pool to prometheus and turning that into a custom metric. (see) Looking at scaling based on job queue length next.

Steps to write own adaptor
If you are using Prometheus or kube-prometheus-stack, you will need https://github.com/kubernetes-sigs/prometheus-adapter We are using it to scale our Pods based on number of messages in RabbitMQ queue. There also a walkthrough on https://github.com/kubernetes-sigs/prometheus-adapter/blob/master/docs/walkthrough.md

Advanced Features of Kubernetes' Horizontal Pod Autoscaler
Prometheus adapter to get custom/external metrics from Prometheus instance into Kubernetes API.

Pod spread by percentage
I never tested this but you have customized metrics API if the value % is available should work from my point of view Check this here https://github.com/kubernetes-sigs/prometheus-adapter

Practical Introduction to Kubernetes Autoscaling Tools with Linode Kubernetes Engine
CPU and memory might not be the right metrics for your application to make scaling decisions. In such cases, you can use HPA (or VPA) with custom metrics as an alternative. To use custom metrics for autoscaling, you can use a custom metrics adapter instead of the Kubernetes Metrics Server. Popular custom metrics adapters are the Prometheus adapter and Kubernetes Event-Driven Autoscaler (KEDA).

Upgrading Hundreds of Kubernetes Clusters
The second one is a combination of tools: External DNS, cert-manager, and NGINX ingress. Using these as a stack, you can quickly deploy an application, making it available through a DNS with a TLS without much effort via simple annotations. When I first discovered External DNS, I was amazed at its quality.

Kubernetes External DNS provider for Hetzner
One of the reasons why I chose Hetzner was that it WAS supported by the ExternalDNS project. I didn't quite understand why the Hetzner provider was pulled, but I saw that an attempt of re-adding it was refused, on the ground that the upcoming webhook architecture would have allowed to better maintain providers.

Looking for ExternalDns alternative for non k8s environment
so I am looking at having an automated way for new routers registered in Traefik to also have the corresponding DNS entry added to my Pihole instance similar to external-dns but obviously, this is exclusive to ingress on k8s environments. my current setup is traefik in a container on unraid.

Is a Load Balancer necessary for a HA Cluster?
You technically don’t need to run a load balancer or have a virtual IP for your control plane. If you control your dns, you can add an A record pointing to all IPs for your control plane nodes. It won’t load balance your traffic, but combined with something like External DNS it gives you HA for the control plane.
-
How can I assign an EIP to a Kubernetes deployment?
I normally deploy external-dns, which automatically updates DNS with the ingress controller's external IP address.

Cluster nodes on different networks
3) Use the Kubernetes External-DNS. I've never used this, but this is assuming it can update DNS for each pods/app to point to the correct Node (it'd need to update my Homelab DNS running on Windows Server)

I am stuck on learning how to provision K8s in AWS. Security groups? ALB? ACM? R53?
So here’s the solution I have taken for our current stack. EKS and its dependencies are created through terraform using the eks module as well as provision a route53 subdomain and a wildcard cert. Once we have that created, I have installed this deployment into the cluster via the helm module: https://kubernetes-sigs.github.io/aws-load-balancer-controller/v2.4/. This allows me to use kuberentes resources (load balancers or ingress objects) and it will handle all the provisioning of load balancers and security groups for me, based on my application yaml and annotations. We also use https://github.com/kubernetes-sigs/external-dns to manage all of our specific host names for the applications through annotations. So to generally put, terraform manages out Kubernetes clusters, and Kubernetes manages the deployment of anything needed for the application including volumes, load balancers, hostnames though Kubernetes system deployments
