terraform-kubestack VS Flux

I've recently released a major update for Kubestack, the Terraform framework for Kubernetes platform engineering teams. This update moves all functionality previously provided by Kubestack Cloud into the kbst CLI.

We've got some overlap on the stack part. But I am more focused on the infra side of platform engineering (including bootstrapping clusters), seems for you it's more app dependencies. Check https://www.kubestack.com and ping me if you're interested in chatting.

With Kubestack, the open-source Terraform framework I maintain, I'm on a mission to provide the best developer experience for teams working with Terraform and Kubernetes. And unified provisioning of all platform components, from cluster infrastructure to cluster services, is something I consider crucial in my relentless pursuit of said developer experience.

In this post I hope to provide a few reasons why frameworks make sense for infrastructure as code, Having tried out Kubestack this got me thinking, Should more of these frameworks exist? And do they provide the same value as a traditional web framework like Flask, Express.js, or Ruby on Rails. Now you might be thinking don't tools like Terraform, Ansible, Chef already exists?

Unsurprisingly, my biased proposal is to use Kubestack to provision the GKE and EKS clusters leveraging the Kubestack framework's unified GKE and EKS modules, and to write a custom module to connect the resulting clusters to Anthos. The bespoke module would integrate the IAM, Anthos and Kubernetes resources required fully into the Terraform state and lifecycle instead of calling kubectl and gcloud like the official Google modules do.

Really cool project. I'll put it on the list of things to integrate with my project Kubestack https://github.com/kbst/terraform-kubestack

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.

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.

CI/CD: Tekton Flux

Use ArgoCD or Flux for Kubernetes, and Serverless Stack for your serverless Lambda applications.

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

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.

Here's our GitHub for Weave Flux and an overview of GitOps

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.

> 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.
