## What it is
Flux v2 is an open and extensible continuous delivery solution for Kubernetes that keeps clusters in sync with Git repositories and OCI artifacts using the GitOps Toolkit. It is a CNCF graduated project built on Kubernetes API extensions, supporting multi-tenancy, Helm and Kustomize, and automated image updates.

## Use cases
- deploy applications to kubernetes with gitops
- keep kubernetes cluster config in sync with git
- automate helm releases on kubernetes
- set up progressive delivery with canary deployments
- automate container image updates to git
- manage kubernetes infrastructure declaratively
- bootstrap gitops on a kubernetes cluster

## When to choose
- you want declarative, auditable continuous delivery driven by Git pull requests
- you need multi-tenancy and syncing of many Git repositories or OCI artifacts
- you use Helm, Kustomize, and standard Kubernetes tooling and want pull-based reconciliation
- you want a CNCF graduated, production-proven GitOps solution with strong security practices

## When to avoid
- you need a push-based CI/CD pipeline with complex build pipelines rather than GitOps reconciliation
- you are not running Kubernetes
- you prefer a UI-first deployment tool over a declarative, CLI/API-driven workflow

## Facets
- artifact type: service
- maturity: stable
- function: deployment, ci-cd, infrastructure-as-code, container-orchestration, monitoring
- domain: cloud-computing, infrastructure-as-code
- platform: cloud, self-hosted, go, cli
- tags: gitops, continuous-delivery, kubernetes-operators, helm, kustomize, cncf-graduated, progressive-delivery, multi-tenancy, devops, containers, kubernetes, automation, docker
