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.

Self-service infrastructure as code
Given the team had already adopted GitOps and were familiar with deployments powered by Helm Releases and Flux, we wanted to move the provisioning of the infrastructure to be part of the same process of creating the service and its continuous deployment.

Weaveworks Is Shuting Down
Your GitHub action can trigger a helm chart, or series thereof, or other infra tools. Declarative specifications, triggered procedurally with the context of the branch’s latest build. We use this pattern quite extensively for preview app workflows.
As of a year ago this is possible in a fully declarative way with Flux 2, but there’s a lot more moving parts and security footguns - and the idea that the maintenance of this project has lost one of its primary sponsors is worrying at best.

10 Ways for Kubernetes Declarative Configuration Management
FluxCD - FluxCD is another popular GitOps tool that allows developers to use a Git repository as the sole source of configuration. Flux automatically ensures that the state of the Kubernetes cluster is synchronized with the configuration in the Git repository. It supports automatic updates, meaning Flux can monitor Docker image repositories for new images and push updates to the cluster.

Best Kubernetes DevOps Tools: A Comprehensive Guide
Flux CD enables continuous deployment to Kubernetes through GitOps by syncing Git repositories with Kubernetes clusters. Flux CD enables GitOps for Kubernetes through source control integration. It manages Kubernetes manifests as code and syncs git repo changes to clusters. Flux automates checks, deployments, and updates within clusters.

Git going with GitOps on AKS: A Step-by-Step Guide using FluxCD AKS Extension
FluxCD is a GitOps tool developed by Weaveworks that allows you to implement continuous and progressive delivery of your applications on Kubernetes. It is a CNCF graduated project that offers a set of controllers to monitor Git repositories and reconciles the cluster's actual state with the desired state defined by manifests committed in the repo.

Ultimate EKS Baseline Cluster: Part 1 - Provision EKS
From here, we can explore other developments and tutorials on Kubernetes, such as o11y or observability (PLG, ELK, ELF, TICK, Jaeger, Pyroscope), service mesh (Linkerd, Istio, NSM, Consul Connect, Cillium), and progressive delivery (ArgoCD, FluxCD, Spinnaker).

Reducing Cloud Costs on Kubernetes Dev Envs
Instead, we will create a single long-lived cluster, and deploy our application in different namespaces. There are a bunch of ways to do that - see ArgoCD, Flux, custom internal tooling, or other solutions (we use our own product). That way, we:

One is to make sure configurations in both clusters is same. And for that there are many tools like fluxcd or projectsveltos

Weaveworks Is Shuting Down
Right. Flux was a handy little tool[1] that sync'd yaml manifests in git repos to live clusters. The concept was fascinating, and the tool was well done--small and efficient. Easy to learn.
In 2019, they announced they'd be "merging" with argocd[2]. It seems the merge never really took place, and after that they deprecated flux and announced flux2[3].
The sudden changes of course were a little confusing and perhaps not too well communicated.

FluxCD - question on configuration/setup in namespaces...
If you are looking at multiple instances of Flux on a cluster which is unmaintained, then most likely you are looking at Flux v1 which is the legacy version and users are all recommended to migrate to the new Flux v2 that has the feature of multiple git repositories and supporting to allow multiple syncs or even multiple tenants.

Automatic subchart updating?
Does a tool like this exist? I am aware of the argoCD image updater which is similar but not quite what I’m looking for, and am aware that flux has an old feature request for this https://github.com/fluxcd/flux/issues/2711

Automation assistants: GitOps tools in comparison
The blog post by Weaveworks, which coined the term GitOps in 2017, also names the first GitOps operator: Flux. In the meantime, this has been completely rewritten as Flux v2. In addition to Flux and Flux v2, the associated project "Flux" develops other components. Weaveworks has now handed the project over to the Cloud Native Computing Foundation (CNCF). By now, the project is in the second maturity level: incubator phase.

Open source Heroku Like Platform on premises
Looks really neat. We have a not-super-trivial rails app that I want to move to docker one day, but kinda scared to make the jump. We're already using docker for development, plus even have a home-grown docker-compose setup for ephemeral labs, but it's clunky at best.
This seems like something that might provide a simple jumping board hopefully... Also bumped into fluxCD[0] recently which also looks interesting.

Kubernetes State Checker
> It doesn't make all the other yaml files happen. It doesn't make the yaml files you no longer want happening, stop happening. It doesn't even tell you "these things were created by 'old' yaml files" and should be garbage collected (since it doesn't seem to have a sense of old yaml files).
This is definitely one piece of Kubernetes that is getting a lot of attention recently. The three tools I've been paying attention to are Argo CD[0], Flux[1], and Config Sync[2].
All of these allow you to point your repository to a cluster and sync resources from the repo to the cluster, including deletes.
