fluxcd.ioflux9s GA: Flux cluster state, from the terminalflux9s, a K9s-inspired terminal UI for Flux, has reached GA. This post covers where it came from, how the Flux Operator's web UI shaped it, and how it grew to cover the whole Flux Operator ecosystem.

Thanks to Dan for sharing the flux9s CLI with the community! It's always lovely to see how people extend and interface with Flux. Check out Dan's writeup here: fluxcd.io/blog/2026/10...

fluxoperator.devTools reference - Flux Operator DocsFlux MCP Server available tools, functions and commands for AI agents

I've been experimenting with local AI (oMLX) on a Mac Studio (M2 Max 96GB) for agentic GitOps. My test bench covers repo analysis and live cluster operations through the Flux MCP server.

Some great things came out of this experiment. The Flux MCP we just released ships with major optimizations and new tools for diffing repo changes against live clusters. Check out the new MCP tools here: fluxoperator.dev/docs/mcp/too...

After Fable and GPT-Sol, the local models felt excruciatingly slow. By next year, I expect the coming wave of lightweight OSS models to shine at agentic GitOps, from manifest generation to handling promotion pipelines across a cluster fleet.

After benchmarking a range of models for a couple of days, I chose Apodex-1.1-mini. I quantized it with Lightning MTP speculative decoding enabled, which made it noticeably faster on my homelab. If you want to try Apodex on oMLX, my quant is on Hugging Face: huggingface.co/stefanprodan...

Check out the new Ignore Rules in Flux :) They let you initialize values but perform selective drift correction. It's now possible to pick the starting replicas when using HPA's instead of relying on the minimum, and cert-manager can now regenerate your placeholder certs fluxcd.io/blog/2026/08...

27 June

I run Claude Code autonomously for days across terminals and IDEs with sub-agents fanning out into copilot, kiro, and gemini. I won't trade that for an agent manager, so I built cctop: a live top for CC to tame the session chaos. Check it out: github.com/stefanprodan...

27 June

Used cctop as an excuse to try Bun instead of my usual Go. Instant startup, genuinely fast, and bun:ffi calls straight into native macOS APIs. Compiles to a single binary too. Bun earned a spot in my toolbox.

Flux v2.8 is out! This release marks the General Availability of Helm v4 features such as server-side apply and enhanced health checking. ❤️ Big thanks to the Helm maintainers for their work on Helm v4 and for collaborating with us to ensure a smooth integration with Flux! fluxcd.io/blog/2026/02...

We've implemented #GitOps actions in the latest Flux Operator Web UI. You can reconcile, pull latest source, and suspend/resume, with more actions to come. Check it out: fluxoperator.dev/web-ui/ ♥️ Big thanks to the #FluxCD users for the feedback that shaped this UI release.

29 Jan

Actions map to custom #Kubernetes RBAC verbs giving cluster admins fine-grained control. User actions are tracked in the Flux Operator audit log, and the Web UI shows you which of your teammates has suspended a reconciliation. Docs here: fluxoperator.dev/docs/web-ui/...

I made a tiny macOS app to help me organise and monitor all the Kubernetes clusters I run #FluxCD tests on. I have lots of these on my laptop, homelab and clouds, so my kubeconfig is always a mess. Give it a try: github.com/stefanprodan...

23 Jan

Last time I developed an app for macOS was years ago in Objective-C. To not spend ages on KSwitch, I went with a spec-driven approach: wrote the features I wanted in markdown and the data models in Swift, then fired off Claude Code and iterated over it for a couple of days.
