awesome-gitops VS Flux

https://github.com/weaveworks/awesome-gitops but also, like, a shell script?

There are books (The Path to GitOps, GitOps and Kubernetes or GitOps Cloud-native Continuous Deployment), whitepapers, and more blog posts than we can manage to count but let us elaborate on the GitOps purpose by taking a quick look on how things evolved in the last few years.

Websites such as awesome-gitops, which was launched by Weaveworks, or gitops.tech, which was put together by INNOQ employees, provide an introductory overview of the available tools. When you take a closer look, you will see that the listed tools can be used to perform a wide variety of tasks related to implementing GitOps, and of course they also differ from one another in terms of their adoption, maturity, and how actively they are maintained. This article identifies three categories from the various use cases: Tools for Kubernetes, supplementary tools, and tools close to infrastructure. In addition, we compiled a table that summarizes the tools and their properties. The tables also contain various Git and GitHub-based metrics (current as of February 2021) that allow you to better assess their adoption, maturity, and how actively they are maintained.

huge fan of k8s. drop what you're doing & use a cross-system object-storage/"apiserver" & control-loops to automate everything; embrace desired state management & thank me latter. but, Heroku &al have a lot of value left.

there's just not that many folk trying to tame deploys on k8s via gitops. flux2 is the rage, it's all over the alpha geek's efforts[1], but it's usually used by someone carefully authoring a fairly complex Helm file, then building out a significant Flux2 HelmRelease object (ex: [2]).

there's a bunch of other tools[3], & i'm frankly not familiar enough. but this idea of having a bunch of source that can deploy itself, simply, is still extremely rare even among the alpha-geek #gitops types. i'm sure some of these tools better match the simplicity of the Heroku model, corresponding branches to environments, which makes so so much sense, but so far i feel like such attempts are still basically unknown.

heroku's really simmered it down to something that made extremely natural sense. huge props to that. too too much of this effort had to go into creating buildpacks & supporting language environments very very carefully very actively, that ability to stealth-containerize an app & not even notice is so much of the special sauce that makes this a hard, hard & eternal problem (because langauges/envs keep changing). there's still a lot of ease of use to Heroku that's potentially will be underrated and/or lost by the oncoming generations. i have high respect for how operateable Heroku is.

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.
