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.

K8s Service Meshes: The Bill Comes Due
Any, it doesn’t matter which as long as you don’t have to count spaces in yaml by hand.
If you really want a concrete recommendation try https://cdk8s.io/.

10 Ways for Kubernetes Declarative Configuration Management
CDK8s - CDK8s is used to define Kubernetes resources and applications. CDK8s uses the high-level abstraction concept called constructs to represent various Kubernetes resources such as deployments, services, and configurations. Developers can write code in programming languages like TypeScript, Python, and Java, and CDK8s will translate this code into standard Kubernetes YAML manifests that can be directly applied to a Kubernetes cluster.

I built a React renderer for Kubernetes configurations
Have you looked into https://cdk8s.io/? I've been using it for a while now, and I must admit TypeSript does help a lot. Not really sold on your React syntax yet, but well done nevertheless

How are most EKS clusters deployed?
I, personally, prefer to wrap it in CDKTF/CDK8S in golang and manage with Crossplane Composition Functions, but your mileage may vary. I'm finding way too bugs in CDK's... but it calms me a bit, that Amazon folks actually looking into it.

Ask HN: What's on Your Home Server?
Always love seeing someone else create a similar solution as your own (albiet likely better!).
I have the same setup with K3S running on a couple PIs. You have a nice CI but I decided to use cdk8s[1] which lets you compile Typescript into K8 files. For access I did almost exactly the same but with CloudFlare Tunnels (might look into Tailscale). Stealing the zigbee2mqtt and room assistant ideas.
Where do you store volumes? I eventually just bought a NAS and mount persistent NFS volumes off it.

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.

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

Kubernetes as a Platform vs. Kubernetes as an API
Disclaimer: I work for AWS but had nothing to do with this blog post (I'm seeing it for the first time with everyone else here).
I think this is an unfair summary of the post. Of course, using Kubernetes to orchestrate other AWS services is going to be a go-to example on the _AWS_ blog, but there is plenty of vendor-agnostic software doing similar things: DNS Records[1], Databases[2], even using Kubernetes CRDs to deploy Kubernetes[3].
The idea of using Kubernetes as an API to orchestrate external resources doesn't inherently lock you into any single vendor.

Does it make sense to use nginx on top of the ingress-nginx
For the average developer an Ingress is substantially simpler to understand. For an expert such as yourself there are additional annotations which may be added, to use nginx specfic features. However the big win using the nginx ingress controller is integration with other Kubernetes features like cert manager and External DNS

I can then set annotations on the Ingress resource to tell external-dns to flip the proxy switch on the DNS record in Cloudflare:

Istio woes on eks 1.22 - external-dns version stuck to v0.7.2
according to users in this issue they claim the external-dns image being a cause of their dns failing on kubernetes 1.22. https://github.com/kubernetes-sigs/external-dns/issues/961
