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 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

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.

Blog: KWOK: Kubernetes WithOut Kubelet
Docker Desktop runs dockerd in a Linux VM with Apple's hypervisor framework. You can also run containers in a Linux VM with Parallels or VMware Fusion hypervisors. But you can't run VMs inside those VMs as it stands today. This works fine on Intel Macs which means you can't experiment and use KVM - one of the killer features of Linux and things like https://kubevirt.io/

Docker + portainer vs k8. EILI5
Proxmox VE can run VMs and LXC containers (see my comment below on LXC). Kubernetes can run OCI containers, but there's also KubeVirt for running VMs.

Live Switching Pods to another Node on Resource Limits
Another option would be something like KubeVirt but that is a different use case where you are actually running a VM in a container for hard-to-containerize workloads.
