# What is Flux CD?

Flux CD, Easy (Beginner), Concepts. https://k8wiz.com/uquiz/what-is-flux-cd

- A. A container runtime that replaces containerd on every node
- B. A GitOps tool that syncs a cluster with configuration stored in Git or OCI
- C. A service mesh that routes and encrypts traffic between pods
- D. A CI system that builds and tests container images from Git

**Answer:** A GitOps tool that syncs a cluster with configuration stored in Git or OCI

**Explanation:** Flux is a set of Kubernetes controllers that pull the desired state from sources such as Git repositories, OCI artifacts and Helm repositories, and apply it to the cluster. It keeps checking, so changes made directly in the cluster are put back to what the source declares.
