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.

Why the fuck are we templating YAML? (2019)
I would recommend implementing a similar API to Grafana Tanka: https://tanka.dev
When you "synthesise", the returned value should be an array or an object.
1. If it's an object, check if it has an `apiVersion` and `kind` key. If it does, yield that as a kubernetes object and do not recurse.

What Is Wrong with TOML?
Maybe you'd like jsonnet: https://jsonnet.org/
I find it particularly useful for configurations that often have repeated boilerplate, like ansible playbooks or deploying a bunch of "similar-but" services to kubernetes (with https://tanka.dev).
Dhall is also quite interesting, with some tradeoffs: https://dhall-lang.org/
A few years ago I did a small comparison by re-implementing one of my simpler ansible playbooks: https://github.com/retzkek/ansible-dhall-jsonnet

Show HN: Keep β GitHub Actions for your monitoring tools
- validation is often impractical (at least identifying exactly where the error isβ¦ Iβm looking at you Helm!)
Unrelated to OP, but you can leverage Tanka to extend helm charts with functionality not provided by upstream.

Alternatives to Helm?
Although jsonette might be considered more complex Tanka is a great alternative for k8s config management.
- Helm makes it overly complex, or is it just me?

The YAML Document from Hell
At Grafana Labs we're using jsonnet at scale, while being a powerful functional language it is also excellent for rendering JSON/YAML config. We have developed Tanka[0] to work with Kubernetes, for other purposes I can recommend this course[1] (authored by me).

Should i migrate from Kustomize to Helm?
If you're hitting the limits of Kustomize, maybe look at Tanka as well.
-
Is it possible to wrap Kustomize yaml with jinja2?
Yes, try Tanka.
-
Using Docker β Compose in Development and Production
yes. basically. and this is a path that multiple people are trying to solve. e.g. AWS CDK8s, https://tanka.dev/, etc
Compose would be awesome.

Google Kubernetes clusters config checker tool

(Note I work for Grafana Labs who fund Tanka and use it for all production config)

Reintroducing a jsonnet-controller for fluxcd
I posted last week about a proof-of-concept kubecfg-operator that would potentially integrate with flux. The project evolved rapidly into what is now an (almost fully) GitOps-toolkit integrated, newly renamed jsonnet-controller. It still supports kubecfg style code, with (untested) tanka support as well. The repo is renamed as well and you can find it here.
What are some alternatives?
helm-charts - Prometheus community Helm charts
tofu-controller - A GitOps OpenTofu and Terraform controller for Flux
kustomize - Customization of kubernetes YAML configurations
kube-libsonnet - Bitnami's jsonnet library for building Kubernetes manifests
kapitan - Generic templated configuration management for Kubernetes, Terraform and other things
etcd - Distributed reliable key-value store for the most critical data of a distributed system [Moved to: https://github.com/etcd-io/etcd]
ytt - YAML templating tool that works on YAML structure instead of text
qbec - configure kubernetes objects on multiple clusters using jsonnet
kpt - Automate Kubernetes Configuration Editing
kubecfg - A tool for managing complex enterprise Kubernetes environments as code.
Pulumi - Pulumi - Infrastructure as Code in any programming language. Build infrastructure intuitively on any cloud using familiar languages π
kubernetes - Production-Grade Container Scheduling and Management
