# Migration: Steps needed between the versions
|
|
|
|
## v3.0 to v3.1
|
|
|
|
### Kubernetes Provider RBACs
|
|
|
|
Starting with v3.1, the Kubernetes Providers now use the [EndpointSlices API](https://kubernetes.io/docs/concepts/services-networking/endpoint-slices/) (Kubernetes >=v1.21) to discover service endpoint addresses.
|
|
|
|
Therefore, in the corresponding RBACs (see [KubernetesIngress](../routing/providers/kubernetes-ingress.md#configuration-example), [KubernetesCRD](../reference/dynamic-configuration/kubernetes-crd.md#rbac), and [KubernetesGateway](../reference/dynamic-configuration/kubernetes-gateway.md#rbac) provider RBACs),
|
|
the `endpoints` right has to be removed and the following `endpointslices` right has to be added.
|
|
|
|
```yaml
|
|
...
|
|
- apiGroups:
|
|
- discovery.k8s.io
|
|
resources:
|
|
- endpointslices
|
|
verbs:
|
|
- list
|
|
- watch
|
|
...
|
|
```
|
|
|
|
#### Gateway API: KubernetesGateway Provider
|
|
|
|
In v3.1, the KubernetesGateway Provider is no longer an experimental feature.
|
|
It can be enabled without the associated `experimental.kubernetesgateway` option, which is now deprecated.
|
|
|
|
??? example "An example of the experimental `kubernetesgateway` option"
|
|
|
|
```yaml tab="File (YAML)"
|
|
experimental:
|
|
kubernetesgateway: true
|
|
```
|
|
|
|
```toml tab="File (TOML)"
|
|
[experimental]
|
|
kubernetesgateway=true
|
|
```
|
|
|
|
```bash tab="CLI"
|
|
--experimental.kubernetesgateway=true
|
|
```
|
|
|
|
##### Remediation
|
|
|
|
The `kubernetesgateway` option should be removed from the experimental section of the static configuration.
|
|
To configure `kubernetesgateway`, please check out the [KubernetesGateway Provider documentation](../providers/kubernetes-gateway.md).
