+# ingresscontroller
+
+  ## Description
+
+  Configures the IngressController object.
+
+This Helm Chart is configuring the IngressController and can set a replica, nodeSelector and tolerations.
+
+## Dependencies
+
+This chart has the following dependencies:
+
+| Repository | Name | Version |
+|------------|------|---------|
+
+It is best used with a full GitOps approach such as Argo CD does. For example, https://github.com/tjungbauer/openshift-clusterconfig-gitops (see folder cluster/management-cluster/ingresscontroller)

+## Example values
+
+```yaml
+---
+---
+# -- Define ingressControllers
+# Multiple might be defined.
+ingresscontrollers:
+    # -- Name of the IngressController. OpenShift initial IngressController is called 'default'.
+  - name: default
+
+    # -- Enable the configuration
+    # @default -- false
+    enabled: true
+
+    # -- Number of replicas for this IngressController
+    # @default -- 2
+    replicas: 3
+
+    # -- Bind IngressController to specific nodes
+    # Here as example for Infrastructure nodes.
+    # @default -- empty
+    nodePlacement:
+
+      # NodeSelector that shall be used.
+      nodeSelector:
+        key: node-role.kubernetes.io/infra
+        value: ''
+
+      # -- Tolerations, required if the nodes are tainted. 
+      tolerations:
+        - effect: NoSchedule
+          key: node-role.kubernetes.io/infra
+          operator: Equal
+          value: reserved
+        - effect: NoExecute
+          key: node-role.kubernetes.io/infra
+          operator: Equal
+          value: reserved
+```
+
+## Installing the Chart
+
+To install the chart with the release name `my-release`:
+
+```console
+helm install my-release tjungbauer/<chart-name>>
+```
+
+The command deploys the chart on the Kubernetes cluster in the default configuration.
+
+## Uninstalling the Chart
+
+To uninstall/delete the my-release deployment:
+
+```console
+helm delete my-release
+```
+
+The command removes all the Kubernetes components associated with the chart and deletes the release.
