## Uninstall
You can uninstall the Flux components with:
You can uninstall Flux with:
```sh
flux uninstall --crds
flux uninstall --namespace=flux-system
```
The above command will delete the custom resources definitions, the
controllers, and the namespace where they were installed.
The above command performs the following operations:
- deletes Flux components (deployments and services)
- deletes Flux RBAC (service accounts, cluster roles and cluster role bindings)
- removes the Kubernetes finalizers from Flux custom resources
- deletes Flux custom resource definitions and custom resources
- deletes the namespace where Flux was installed
If you've installed Flux in a namespace that you wish to preserve, you
can skip the namespace deletion with:
```sh
flux uninstall --namespace=infra --keep-namespace
```
!!! hint
Note that the `uninstall` command will not remove any Kubernetes objects
or Helm releases that were reconciled on the cluster by Flux.
