When editing clusters, clusters that are [launched using RKE]({{< baseurl >}}/rancher/v2.x/en/cluster-provisioning/rke-clusters/) feature more options than clusters that are imported or hosted by a Kubernetes provider. The headings that follow document options available only for RKE clusters.
### Upgrading ingress-nginx
### Updating ingress-nginx
For RKE v0.1.8+, the `ingress-nginx` YAML does not contain an `updateStrategy`. Therefore, the `updateStrategy` is the default value that is set by the Kubernetes API version. For example, the default `updateStrategy` for Kubernetes v1.13 was `onDelete`. When RKE v0.3.2 began supporting Kubernetes v1.16, the `updateStrategy` for `ingress-nginx` became `RollingUpdate` by default for RKE clusters with Kubernetes 1.16. This policy allows the daemonset to restart the pods.
For RKE prior to v0.1.8, the `updateStrategy` directive in the `ingress-nginx` YAML was set to `OnDelete` because RKE did not yet support updating ingress and addons. In that case, you will need to delete these pods to get the correct version for your deployment.
Clusters that were created before Kubernetes 1.16 will have an `ingress-nginx` `updateStrategy` of `OnDelete`. Clusters that were created with Kubernetes 1.16 or newer will have `RollingUpdate`.
If the `updateStrategy` of `ingress-nginx` is `OnDelete`, you will need to delete these pods to get the correct version for your deployment.
