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.

The Inner Workings of Kubernetes Management Frontends — A Software Engineer’s Perspective
The Kubernetes clients (e.g., Go client) support developers with both methods to connect to a cluster, as we can see in the following examples.

Has anyone ever tried to learn how k8s works?
My suggestion would be to start looking at things like https://github.com/kubernetes/client-go first in order to get a feel for the API and how data plane k8s components interact with the apiserver (it's the same thing that kubelet uses). Then move on to trying to build your own k8s operator to get a feel for how people expand and customize k8s functionality without having to modify upstream at all. IMO the codebase itself is too messy and in constant flux to make too much sense of it unless you are planning to contribute to upstream.

CUE compared to helm/kustomize...
CUE is cool and all but as soon as I start writing real code structures I want to reach for client-go.

Go 1.21 will (probably) download newer toolchains on demand by default
I'm... really not sure I agree with this, from a philosophical point of view. It feels like this is making "eh, we'll just upgrade our Go version next quarter" too easy; ultimately some responsibility toward updating your application's Go version to work with what new dependencies require should fall on Us, the application developers. Sure, we're bad at it. Everyone's lived through running years-old versions of some toolchain. But I think this just makes the problem worse, not better.
Its compounded by the problem that, when you're setting up a new library, the `go` directive in the mod file defaults to your current toolchain; most likely a very current one. It would take a not-insignificant effort on the library author's part to change that to assert the true-minimum version of Go required, based on libraries and language features and such. That's an effort most devs won't take on.
I'd also guess that many developers, up-to this point if not indefinitely because education is hard, interpreted that `go` directive to mean more-of "the version of go this was built with"; not necessarily "the version of go minimally required". There are really major libraries (kubernetes/client-go [1]) which assert a minimum go version of 1.20; the latest version (see, for comparison, the aws-sdk, which specifies a more reasonable go1.11 [2]). I haven't, you know, fully audited these libraries, but 1.20 wasn't exactly a major release with huge language and library changes; do they really need 1.20? If devs haven't traditionally operated in this world where keeping this value super-current results in actually significant downstream costs in network bandwidth (go1.20 is 100mb!) and CI runtime, do we have confidence that the community will adapt? There's millions of Go packages out there.
Or, will a future version of Go patch a security update, not backport it more than one version or so, and libraries have to specify the newest `go` directive version, because manifest security scanning and policy and whatever? Like, yeah, I get the rosy worldview of "your minimum version encodes required language and library features", but its not obvious to me that this is how this field is, or even will be, used.
Just a LOT of tertiary costs to this change which I hope the team has thought through.

How to list all kubernetes objects with specific label using client-go
I looked at dynamic package, but it seems like it needs GroupVersionResource, which is different for, say, Service objects and Deployment objects. Also when I pass schema.GroupVersionResource{Group: "apps", Version: "v1"} it doesn't find anything, when I pass schema.GroupVersionResource{Version: "v1"} it finds only namespace object and also doesn't looks for labels, though I provided label options:
-
What's the best way to get notified when kubernetes Deployments change using the k8s.io/client-go library?
I'm writing a script that uses the k8s.io/client-go library (godocs here) to manipulate Deployments. In particular, I want to add a label selector to every Deployment in my cluster. Deployment label selectors are immutable. So my approach is to:
- K8S Get deployment liveness probe status
-
Learning kubebuilder - good examples of Golang watching/manipulating k8s objects?
Actually, kubebuilder is not using the standard Go libraries, but one using reflection to dynamically resolve the client based on the type you hand it (which is arguably better). The "official" client is k8s.io/client-go.

My LFX Mentorship experience with OpenELB
Then on June 18th, 2022, I got a chance to meet our mentors and the other mentee of OpenELB (the mentee and the mentors of OpenFunction were also there). There I was informed about how to start working on the project, so I started learning about using the Kubernetes API client. After experimenting with the official Kubernetes Client, I learned that it's not very feasible to use that for dealing with CRDs (custom resource definitions), so I explored the controller-runtime client as per what I found in many sources, and found that it was a great fit for the backend of our project. During that time, I also built a simple project to see if everything would work as expected or not (as this was the first time I dealt with a Kubernetes client, I considered that debugging would be easier in a smaller project).

Looking for library recommendations: Django -> Golang port
I figured I'd ask the community for some recommendations for the following capabilities that Django + python stack is giving me at the moment: 1. Amazon SES Mailing (considering - aws-sdk-go) 2. Django Admin (considering go-admin 3. Django Signals (considering syncsignals 4. Celery (No contenders here)

AWS and its complicated shit needs to die
Counterpoint 2: Amazon is bad and should feel bad for making this an internal and embedding it in the Credentials struct.
What are some alternatives?
kubebuilder - Kubebuilder - SDK for building Kubernetes APIs using CRDs
minio-go - MinIO Go client SDK for S3 compatible object storage
controller-runtime - Repo for the controller-runtime subproject of kubebuilder (sig-apimachinery)
Moto - A library that allows you to easily mock out tests based on AWS infrastructure.
kustomize - Customization of kubernetes YAML configurations
botocore - The low-level, core functionality of boto3 and the AWS CLI.
celery - Distributed Task Queue (development branch)
twitter-scraper - Scrape the Twitter frontend API without authentication with Golang.
