Kubernetes: The platform Flux delivers into
Overview
What Flux does
Flux is a set of continuous delivery tools for Kubernetes built on the GitOps model: the desired state of a cluster lives in Git, and controllers running inside the cluster continuously reconcile reality against it. The security argument is the strong one. In a push-based pipeline, CI holds cluster credentials, so anyone who compromises CI reaches production. With Flux the cluster pulls, and no external system needs write access to it. Drift is also corrected automatically, because reconciliation is continuous rather than a one-off deploy.
What people use it for
- Removing cluster credentials from CI systems
- Keeping many clusters consistent with a single declared state
- Automatically correcting configuration drift rather than discovering it later

The honest half
Where it falls short
Concrete and checkable, so you can decide whether any of them matter to you. This is the half of a review a vendor will not write about Flux.
- No user interface of its own: observing what Flux is doing means CLI or a third-party dashboard
- Debugging a stuck reconciliation is harder than reading a pipeline log, because failure is asynchronous
- Everything must be in Git, which is awkward for secrets and needs a sealed-secrets or external-secrets approach
- GitOps is a workflow change, not just a tool, and teams used to imperative deploys find the adjustment real

Questions people ask
Each answer names the page it came from, so you can check it rather than take our word for it.
Is Flux free?
Yes, open source and CNCF-graduated.
Flux or Argo CD?
Both implement GitOps. Argo CD ships a strong web UI and is often preferred for visibility; Flux is more modular and composes as controllers, which suits platform teams.
Why is pull-based safer?
Because the cluster reaches out to Git rather than CI reaching into the cluster. No external system needs write credentials to production.
