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.

CNAB

Kubernetes Application Archive !! Bundle up a Kubernetes application 📦 into a single static OCI compliant archive.
Similar to https://cnab.io/ then?
-
Stronger abstraction for deployments
IMO Cloud native application bundle is what you are looking for: https://cnab.io/
-
Deployment Packaging Solutions
have you looked at CNAB ? since it uses standard OCI compliance you can have your entire application bundle on Azure registry (azure registry is OCI 2 compliant registry) and you can get more information about how to do it using ORAS cli
- Tools to Run Kubernetes Locally
-
k8s based platform
Check https://cnab.io/ and https://porter.sh/

Terraform 1.0 Release
I'm closely tracking an effort by Microsoft that aims to do a lot of what you're describing since I find myself bridging between these tools and deploying stacks that span tools and roles. [CNAB](https://cnab.io/) and the front-running implementation, [Porter](https://porter.sh/), enable one-step infra deployments, packaged as a single OCI-compatible container, with any number of steps, using the best tools for each of those steps. Think of using aws-cli for some initialization step (create or verify presence of a state bucket), applying some terraform to create infra, and finishing with a helm chart to complete deployment of app components. Each stage in a bundle packages not only the code to run it but also the execution binary of the tool that runs it. The spec and porter are still a moving target but it's a promising space and a nice adjacent evolution of the current state of tooling.

Ask HN: What you up to? (Who doesn't want to be hired?)
I'm continuing to work on https://concise-encoding.org which is a new security-conscious ad-hoc encoding format to replace JSON/XML and friends. I've been at it for 3 years so far and am close to a release.
In a nutshell:
- Edit in text, transmit in binary. One can be seamlessly converted to the other, but binary is far more efficient for processing, storage and transmission, while text is better for humans to read and edit (which happens far less often than the other things).
- Secure by design: Everything is tightly specced and accounted for so that there aren't differences between implementations that can be exploited to compromise your system. https://github.com/kstenerud/concise-encoding/blob/master/ce...
- Real type support because coercing everything into strings sucks (and is another security risk and source of incompatibilities).
XML had a good run but was replaced by JSON which was a big improvement. JSON also had a good run but it's time for it to retire now that the landscape has changed even further: Security and efficiency are the desires of today, and JSON provides neither.
I've got the spec nailed down and can finally see the light at the end of the tunnel for the reference implementation in golang. I still need to come up with a system for schemas, but I'm hoping that https://cuelang.org will fit the bill.

No YAML
Has anyone taken a look at Cue who can share any experiences?
https://cuelang.org/
It's mentioned on the site as an alternative to Yaml. Recently watched (~half of) this intro to it: https://youtu.be/fR_yApIf6jU
- Ask HN: Is there a good way to run integration tests on Kubernetes?

Cue: A new language for data validation
the most interesting summary explanation of cue lang and its differences is from a bug filing - https://github.com/cuelang/cue/issues/33
>CUE is a bit different from the languages used in linguistics and more tailored to the general configuration issue as we've seen it at Google. But under the hood it adheres strictly to the concepts and principles of these approaches and we have been careful not to make the same mistakes made in BCL (which then were copied in all its offshoots). It also means that CUE can benefit from 30 years of research on this topic. For instance, under the hood, CUE uses a first-order unification algorithm, allowing us to build template extractors based on anti-unification (see issue #7 and #15), something that is not very meaningful or even possible with languages like BCL and Jsonnet.

CMake proposal: Unified way of describing dependencies of a project
I agree with you. Personally, I think Cue is much better than either YAML, TOML or JSON because it adds the concept of types to the idea of describing configuration.

Cloud Infrastructure as SQL
true, but the tooling and workflow remains the same.
Not sure of any tool that could abstract the details sufficiently to be widely adopted. There is just too much nuance in cloud config.
I'm exploring using CUE (https://cuelang.org) to define TF resources, exporting as JSON for TF. So far it's much nicer
What are some alternatives?
kapp-controller - Continuous delivery and package management for Kubernetes.
terraform - Terraform enables you to safely and predictably create, change, and improve infrastructure. It is a source-available tool that codifies APIs into declarative configuration files that can be shared amongst team members, treated as code, edited, reviewed, and versioned.
helm-charts - Komodor.io public helm charts
dhall-lang - Maintainable configuration files
kubevela - The Modern Application Platform.
jsonnet - Jsonnet - The data templating language
porter - Porter enables you to package your application artifact, client tools, configuration and deployment logic together as an installer that you can distribute, and install with a single command.
Pulumi - Pulumi - Infrastructure as Code in any programming language. Build infrastructure intuitively on any cloud using familiar languages 🚀
ytt - YAML templating tool that works on YAML structure instead of text
