+description: Install the Redis Enterprise for Kubernetes version 7.8.Wisconsin using helm charts.
+linkTitle: Helm
+weight: 11
+---
+
+Helm charts provide a simple way to install the Redis Enterprise for Kubernetes operator in just a few steps. For more information about Helm, go to [https://helm.sh/docs/](https://helm.sh/docs/).
+
+{{<note>}} This feature is currently in public preview and is not supported on production workloads. Only new installations of the Redis operator are supported at this time. The steps for [creating the RedisEnterpriseCluster (REC)]({{<relref "operate/kubernetes/deployment/quick-start/#create-a-redis-enterprise-cluster-rec">}}) and other custom resources remain the same.{{</note>}}
+
+## Prerequisites
+
+- A [supported distribution]({{< relref "/operate/kubernetes/reference/supported_k8s_distributions.md" >}}) of Kubernetes.
+- At least three worker nodes.
+- [Kubernetes client (kubectl)](https://kubernetes.io/docs/tasks/tools/).
+- [Helm 3.10 or later](https://helm.sh/docs/intro/install/).
+
+## Install
+
+1. Add the `redis-enterprise-helm` repository.
+
+    ```sh
+    helm repo add redis-enterprise-helm https://helm.redis.io/
+    ```
+
+1. Install the Helm chart into a new namespace.
+
+    ```sh
+    helm install <operator-name> redis-enterprise-helm/redis-enterprise-operator \
+        -- version <release-name> \
+        -- namespace <namespace-name> \
+        -- create-namespace
+    ```
+
+To install with Openshift, add `--set openshift.mode=true`.
+
+To monitor the installation add the `--debug` flag. The installation runs several jobs synchonously and may take few minutes to complete.

+
+## Configuration
+
+See [`values.yaml`](https://github.com/RedisLabs/redis-enterprise-operator/blob/master/deploy/helm/redis-enterprise-operator/values.yaml) for the default values.
+
+### Install with values file
+
+1. View configurable values with `helm show values`.
+
+2. Create a YAML file with the values you wish to configure.
+
+3. Install the chart with the `--values` option.
+
+    ```sh
+    helm install <operator-name> redis-enterprise-helm/redis-enterprise-operator \
+        -- version <release-name> \
+        -- namespace <namespace-name> \
+        -- create-namespace
+        -- values <path-to-values-file>
+    ```
+
+### Install and override specific default values
+
+## Uninstall
+
+1. Delete any custom resources managed by the operator. See [Delete custom resources]({{<relref "content/operate/kubernetes/re-clusters/delete-custom-resources.md">}}) for detailed steps. Custom resources must be deleted in the correct order to avoid errors.
+
+1. Uninstall the helm chart.
+
+    ```sh
+    helm uninstall <release-name>
+    ```
+
+This removes all Kubernetes resources associated with the chart and deletes the release.
