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.

Pull through cache, like AWS just announced
If you stop to think about, what AWS is selling here, it's quite funny. Most of the infrastructure behind registry.k8s.io is hosted on AWS (and also GCP). So AWS essentially tells you: Don't trust the upstream registry, it might go down, cache it on your own registry, hosted also by us.

Announcing pull through cache for registry.k8s.io in Amazon Elastic Container Registry
For example: if you only allow cluster autoscaler and metrics server from registry.k8s.io you can pull those images through the cache as someone who has create repo IAM privileges. If someone without create repo privileges tries to pull a new image it will fail because they can't create the initial repo.

registry.k8s.io down from Paris, France?
https://registry.k8s.io (the root url at /) redirects you to https://github.com/kubernetes/registry.k8s.io where we have an issue tracker.

How to own your own Docker Registry address
Hosting a forwarding / redirect server instead of actually hosting images is probably a decent idea.
The K8s proxy is redirecting from only hosting on GCR to community-owned registries - https://kubernetes.io/blog/2023/03/10/image-registry-redirec...
You can view the code here - https://github.com/kubernetes/registry.k8s.io
But because everyone is already pointing at gcr.io (just like many openfaas users point at docker.io/) - they're having to do a huge campaign to announce the new URL - the same would apply with the author's solution here.
I wrote some automation for hosting (not redirects) in arkade with the OSS registry - Get a TLS-enabled Docker registry in 5 minutes - https://blog.alexellis.io/get-a-tls-enabled-docker-registry-...
The registry is also something you can run on a VM if you so wish, and have act as a pull through cache.
Apart from reliability - GitHub's container registry is the current next best option - but we have to ask ourselves, what happens when they start charging or the outages start to last longer or are more frequent than 1-2 times per week as we've seen in Q1 2023.

Docker's deleting Open Source images and here's what you need to know
One annoyance with how docker images are specified is they include the location where they are stored. So if you want to change where you store you image you break everyone.
I wonder if what regsitry.k8s.io does could be generalized:
https://github.com/kubernetes/registry.k8s.io/blob/main/cmd/...
The idea is the depending on which cloud you are pulling the image from, they will use the closest blob store to service the request. This also has the effect that you could change the source of truth for the registry without breaking all Dockerfiles.

k8s.gcr.io Image Registry Will Be Frozen From the 3rd of April 2023
If you are using updated helm charts then most of them have already replaced with registry.k8s.io, for example nginx ingress so not really breaking change.

How I use Devbox in my Elm projects
Before I went on my Christmas vacation last year I wrote an article on how I use Nix in my Elm projects. At the time, I was pleased with my set up. However, not even a month would go by before my satisfaction was questioned. In early January, Carlo Ascani asked a question, on the Elm Discourse, about his Umbra project. I decided to explore his project and I soon discovered two files, devbox.json and devbox.lock, I had never seen before. This piqued my curiosity and I had to learn more. I followed the link to the Devbox website and feverishly read the docs. I... was... hooked. I was pleasantly surprised by its simplicity and it seemed to fit my use cases really well.

PackagingCon – a conference only for software package management
I've spent the last year managing all my packages with Devbox (https://github.com/jetpack-io/devbox).
Local dev, cloud dev, CI, production – all with the same config file. Fingers crossed my talk submission for PackagingCon gets accepted. It'd be awesome to share this new way of working with a wider audience.

NixOS and My Descent into Insanity
> Now to figure out what a "flake" is…
Flake is a worthwhile addition to Nix that is worth learning. But like anything Nixian, it's not straightforward.
Have you checked out any of the tools that aim to simplify Nix experience? We built Devbox (https://github.com/jetpack-io/devbox) with this in mind.

TySON: a native go library that lets you use TypeScript as an embedded configuration language without depending on Node or V8
Also devbox ( https://github.com/jetpack-io/devbox ) which is what this is for does not work on windows because of its Nix dependency.
-
Simplifying preview environments for everyone
For these reasons, I believe most developer environments should prioritize developer experience over fidelity. Tools like Containerized development environments and cloud emulators can strike the right balance and there’s no surprise that we see increased activity around devcontainers, and similar solutions.

Codespaces but open-source, client-only, and unopinionated
Local first, cloud optional is the only way (IMHO) we're going to get people off their local laptop development setups.
We need to support local dev environments first, with the exact same config a developer can then move to the cloud.
See https://github.com/jetpack-io/devbox for how this can be achieved and https://www.mikenikles.com/blog/dev-environments-in-the-clou... for my thoughts after 3 years of working in this space.

Why did Nix adopt Flakes?
If you like the properties of Nix, but find it confusing, you should check out Devbox! It simplifies the process of creating Nix-powered dev environments:

NixTest: a tiny unit testing framework written in pure nix
As part of the work we've been doing with [devbox](https://github.com/jetpack-io/devbox), we needed a unit testing framework to test some of our nix code. Unfortunately we had some use cases where we did *not* want to introduce a dependency on `nixpkgs` (and therefore we couldn't use `runTests`).
What are some alternatives?
official-images - Primary source of truth for the Docker "Official Images" program
devenv - Fast, Declarative, Reproducible, and Composable Developer Environments
cri-o - Open Container Initiative-based implementation of Kubernetes Container Runtime Interface
devpod - Codespaces but open-source, client-only and unopinionated: Works with any IDE and lets you use any cloud, kubernetes or just localhost docker.
one-click-apps - Community Maintained One Click Apps (https://github.com/caprover/caprover)
distrobox - Use any linux distribution inside your terminal. Enable both backward and forward compatibility with software and freedom to use whatever distribution you’re more comfortable with. Mirror available at: https://gitlab.com/89luca89/distrobox
docker-registry-mirror - Helm chart for a Docker registry. Successor to stable/docker-registry chart.
