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.

10 Ways for Kubernetes Declarative Configuration Management
YTT - YTT is a templating tool that understands YAML structure. It helps you easily configure complex software via reusable templates and user provided values using the Starlark language.

Alternatives to Helm/Kustomize for complex Kubernetes Deployments
Adding https://carvel.dev/ytt/ to the list. I was happy using this tool as IMO it mixes good things from Helm and Kustomize, however the syntax is ugly and repelling my colleagues to have a closer look.

The YAML Document from Hell
> Templating yaml is a terrible, terrible idea
I've had a good time using ytt: https://carvel.dev/ytt/. It implements language-aware templating, which is IMO the only reasonable way to do it.

Creating Kubernetes Templates
`ytt` is part of the Carvel toolchain. https://carvel.dev/ytt/

Dealing with YAML overload
I agree with you on `you will want to see just plain texts instead of a bunch of templating token with hidden logic.` Which is why I think https://carvel.dev/ytt/ would be great. We could generate these templates in pipelines, or we could just make it easier to maintain what we have.

How to handle the lifecycle of multiple COTS
For more advanced configuration management you might be interested in ytt ( https://carvel.dev/ytt/ ) which is a "yaml-aware" templating tool. it lets you do "patches" via an overlay mechanism to add or remove specific yaml blocks, and it also lets you use a simplified python dialect for more complicated logic. With ytt you would put your DNS IP into a "data values" file and then run ytt to render it into the configs before handing them off to the deployment tool. e.g. `ytt -f | kubectl apply`

The Dhall Configuration Language
https://carvel.dev/ytt/
ytt lets you embed logic via a python-subset (starlark) and also provides "overlays" as a "replace/insert" mechanism. and all valid ytt files are valid yaml files, so they can be passed-through other yaml parsing stages.
I said this above as well: ytt (https://carvel.dev/ytt/) lets you embed starlark into valid yaml, among other cute tricks for managing biz-logic in configs.

Would a visual drag and drop builder for K8s clusters be useful to people here?
There's a reason that other tooling is taking different approaches. Visual workflows help for understanding existing manifests - but they'd be horrible for creating/modifying new ones.

Ask HN: Why Are Git Submodules So Bad?
i never found myself struggling with submodules, but at times i found myself just slightly annoyed (especially when having to remove/replace submodules), especially when they are used for simpler use cases.
i actually ended up creating https://carvel.dev/vendir/ for some of the overlapping use cases. aside from not being git specific (for source content or destination), its entirely transparent to consumers of the repo as they do not need to know how some subset of content is being managed. (i am of course a fan of committing vendored content into repos and ignore small price of increasing repo size).
