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
We also leverage tools like Kubent, popeye, kdave, and Pluto to help us manage API deprecations (when Kubernetes deprecates features in updates) and ensure the overall health of our infrastructure.
- Best Practices for Upgrading Kubernetes?
-
Updating from 1.25.15 to 1.26.10
kubent has been my goto for this - you point it at your cluster, tell it the target version you want to use, and it'll let you know if you have any depreciated resources and what you'll need to change. It's simple to use, quick, and just does the job.

How do you handle continuous k8s cluster version upgrades in your organization?
You have to constantly run tools like https://github.com/doitintl/kube-no-trouble / https://github.com/FairwindsOps/pluto.

Upgrading our EKS from 1.21 to 1.22
A great tool for checking depreciations is kubent/kube-no-trouble: https://github.com/doitintl/kube-no-trouble

strategy to upgrade eks cluster
https://github.com/doitintl/kube-no-trouble can be used to check for deprecated/removed APIs - you'll need to fix these in your codebase. You should fix these before upgrading your cluster
- choose from Two strategies we can implement to upgrade eks cluster
- Amazon EKS now support Kubernetes version 1.25

eks cluster upgrade Anyone has done eks cluster upgrade to upgrade the cluster from 1.21 to 1.22 there are some api resources kind need to changed, which need changes in manifest file changes. how do we identify the helm charts that are using these resources ? https://docs.aws.amazon.com/eks/lat
Just upgraded a few clusters from 1.21 to 1.24 the past few weeks. Used kubent (Kube No Trouble https://github.com/doitintl/kube-no-trouble) before upgrading and reviewed the output. Pretty painless process all in all.

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.

Run WebAssembly on DigitalOcean Kubernetes with SpinKube - In 4 Easy Steps
On top of its core components, SpinKube depends on cert-manager. cert-Manager is responsible for provisioning and managing TLS certificates that are used by the admission webhook system of the Spin Operator. Let’s install cert-manager and KWasm using the commands shown here:

Importing kubernetes manifests with terraform for cert-manager
terraform { required_providers { kubectl = { source = "gavinbunney/kubectl" version = "1.14.0" } } } # The reference to the current project or a AWS project data "google_client_config" "provider" {} # The reference to the current cluster or EKS data "google_container_cluster" "my_cluster" { name = var.cluster_name location = var.cluster_location } # We configure the kubectl provider to use those values for authenticating provider "kubectl" { host = data.google_container_cluster.my_cluster.endpoint token = data.google_client_config.provider.access_token cluster_ca_certificate = base64decode(data.google_container_cluster.my_cluster.master_auth[0].cluster_ca_certificate) } #Download the multiple manifests file. data "http" "cert_manager_crds" { url = "https://github.com/cert-manager/cert-manager/releases/download/v${var.cert_manager_version}/cert-manager.crds.yaml" } data "kubectl_file_documents" "cert_manager_crds" { content = data.http.cert_manager_crds.response_body lifecycle { precondition { condition = 200 == data.http.cert_manager_crds.status_code error_message = "Status code invalid" } } } # We use the for_each or else this kubectl_manifest will only import the first manifest in the file. resource "kubectl_manifest" "cert_manager_crds" { for_each = data.kubectl_file_documents.cert_manager_crds.manifests yaml_body = each.value }

Easy HTTPS for your private networks
I've been pretty frustrated with how private CAs are supported. Your private root CA can be maliciously used to MITM every domain on the Internet, even though you intend to use it for only a couple domain names. Most people forget to set Name Constraints when they create these and many helper tools lack support [1][2]. Worse, browser support for Name Constraints has been slow [3] and support isn't well tracked [4]. Public CAs give you certificate transparency and you can subscribe to events to detect mis-issuance. Some hosted private CAs like AWS's offer logs [5], but DIY setups don't.
Even still, there are a lot of folks happily using private CAs, they aren't the target audience for this initial release.
