 `minikubecluster` in my environment resolves to the IP address of the minikube's VM which you can get using `minikube ip` command.
-The port numbers in these commands are the `node ports` defined as part of the service spec which map to the internal container ports and to which they forward all the requests. For more information about Node Ports see https://kubernetes.io/docs/concepts/services-networking/service/#type-nodeport.

+# OpenShift Deployment
+
+OpenShift (and other clusters enforcing the `restricted` Pod Security Standard) has stricter security requirements than default Kubernetes. Specifically, it blocks containers that attempt to run as root or use `hostPath` volumes.
+
+SeaweedFS can be deployed on OpenShift by using a specialized Helm values file that overrides the defaults to comply with the `restricted` Security Context Constraints (SCC).
+
+## Steps
+
+1. Use the generic SeaweedFS Helm chart but provide the `openshift-values.yaml` overrides file. This file (located in the chart directory) configures the pods to:
+   - Use `PersistentVolumeClaims` instead of `hostPath`.
+   - Set `runAsNonRoot: true` and omit specific UIDs (allowing OpenShift to automatically assign a valid UID from the namespace's allocated range).
+   - Drop all Linux capabilities and disable privilege escalation.
+   - Use the `RuntimeDefault` seccomp profile.
+
+2. Install the Helm chart with the OpenShift overrides:
+
+```bash
+helm install seaweedfs seaweedfs/seaweedfs \
+  -n seaweedfs --create-namespace \
+  -f https://raw.githubusercontent.com/seaweedfs/seaweedfs/master/k8s/charts/seaweedfs/openshift-values.yaml
+```
+
+*Note: If you have already cloned the repository, you can reference the local file: `-f k8s/charts/seaweedfs/openshift-values.yaml`.*
+
+For more details on the specific settings, see the comments within [openshift-values.yaml](https://github.com/seaweedfs/seaweedfs/blob/master/k8s/charts/seaweedfs/openshift-values.yaml).
