 ## Pre-Requirements
 
 * [OpenShift cluster](https://www.redhat.com/en/technologies/cloud-computing/openshift)
 * Admin access to OpenShift cluster
-* [kubectl installed](https://kubernetes.io/docs/tasks/tools/install-kubectl) and configured to access OpenShift cluster
+* [kubectl](https://kubernetes.io/docs/tasks/tools/install-kubectl) or [oc](https://github.com/openshift/oc) installed and configured to access OpenShift cluster
 * [Helm installed](https://helm.sh/docs/intro/install)
 
-## Install Red Hat OpenShift Logging operator 
+> [!NOTE] Note
+> You can replace every `kubectl` command in this guide with `oc`. They are interchangeable in most cases on OpenShift clusters.
 
-[Cluster logging operator](https://github.com/openshift/cluster-logging-operator) is a logging solution to support aggregated cluster logging. It is using [Vector](https://vector.dev/) for logs collection and shipping to remote storage.
+## Overview
 
-In order to install the operator, navigate to the OpenShift web console and select the `Operators` tab. Then, click on `OperatorHub` and search for `Red Hat OpenShift Logging`. Click on the `Red Hat OpenShift Logging` operator and then click on `Install`.
+To collect OpenShift logs, we're going to:
 
-![Install logging operator](install-oc-logging-operator.webp)
+1. [Install VictoriaLogs](https://docs.victoriametrics.com/guides/collecting-openshift-logs-with-victoria-logs/#install-victoria-logs) in the OpenShift Cluster
+2. [Configure a service account](https://docs.victoriametrics.com/guides/collecting-openshift-logs-with-victoria-logs/#rbac-configuration) to access the logs

-Alternatively, you can use OpenShift console to create the service account and cluster role binding. 
-Navigate to `ServiceAccounts` and click on `Create Service Account`. Fill in the name `victorialogs` and namespace `openshift-logging` and click on `Create`. 
-Then, navigate to `RoleBindings` and create a binding for each `ClusterRole` for subject `victorialogs` in `openshift-logging` namespace.
+Install the roles in OpenShift with:
 
-
-## Install Victoria Logs
-
-Add Victoria Metrics Helm [repository](https://github.com/VictoriaMetrics/helm-charts):
-```bash
-helm repo add vm https://victoriametrics.github.io/helm-charts/
+```shell
+kubectl apply -f vl-rbac.yml
 ```
 
-Minimal configuration for VictoriaLogs running in OpenShift:
-```yaml
-securityContext:
-  enabled: true
-  allowPrivilegeEscalation: false
-  capabilities:
-    drop:
-      - ALL
-  readOnlyRootFilesystem: true
+Alternatively, you can use the OpenShift web console to create the service account and cluster role binding. To do this:
 
-podSecurityContext:
-  enabled: true
-  runAsNonRoot: true
-```
-Save the configuration to `vl.yaml`.
+1. Navigate to **ServiceAccounts**.
+2. Click on **Create Service Account**.
+3. Fill in the name `victorialogs` and namespace `openshift-logging`.
+4. Click on **Create**. 
+5. Navigate to **RoleBindings**.
+6. Create a binding for each `ClusterRole` for subject `victorialogs` in `openshift-logging` namespace.
 
-> Note, that depending on the OpenShift cluster configuration, additional security settings might be required.
+## Install Red Hat OpenShift Logging operator 
 
-Create namespace for VictoriaLogs:
-```bash
-kubectl create namespace vl
-```
+The [Cluster logging operator](https://github.com/openshift/cluster-logging-operator) is a logging solution to support aggregated cluster logging. It is using [Vector](https://vector.dev/) for log collection and shipping to remote storage.
 
-Install VictoriaLogs with the following command:
-```bash
-helm upgrade --namespace vl --install vl vm/victoria-logs-single -f vl.yaml
-```
+To install the operator:
+
+1. Navigate to **Ecosystem** > **Software Catalog**
+2. Search for "OpenShift Logging" and select the operator.
+    ![Screenshot of OpenShift web console](software-catalog-openshift-logging-1.webp)
+3. Press **Install**.
+4. Confirm the settings and press **Install** again.

 ## Configure logs forwarding
 
-Cluster logging operator uses `ClusterLogForwarder` resource for logs forwarding configuration.
+We need to create a `ClusterLogForwarder` resource to forward logs from the OpenShift Logging operator to VictoriaLogs.
 
-Here is an example configuration to forward all cluster logs to VictoriaLogs:
-```yaml
+Run the following command to create the resource file:
+
+```shell
+cat <<EOF > vl-forwarder.yml
 apiVersion: observability.openshift.io/v1
 kind: ClusterLogForwarder

-It is also possible to configure logs forwarding using OpenShift console. Navigate to `Operators` tab and click on `Installed Operators`. Then, click on `Red Hat OpenShift Logging` and navigate to `ClusterLogForwarders`. Click on `Create ClusterLogForwarder`.

+## Verify logs ingestion
+
+We can verify that logs are being collected using the VictoriaLogs VMUI.
+
+First, find the service name for the VMUI with:
+
+```shell
+kubectl get svc -n vl -l app.kubernetes.io/instance=vl
+```
+
+You should get a result similar to this. Note the name of the service:
+
+```text
+NAME                             TYPE        CLUSTER-IP   EXTERNAL-IP   PORT(S)    AGE
+vl-victoria-logs-single-server   ClusterIP   None         <none>        9428/TCP   113s
+```
+
+Then, port-forward the VMUI service console with:
+
+```shell
+kubectl -n vl port-forward svc/vl-victoria-logs-single-server 9428:9428
+```
+
+Open your browser in `http://localhost:9428/select/vmui/#/overview` and verify that logs are being collected. This overview page shows the number of log entries being consumed in real time.
+
+![Screenshot of VMUI for VictoriaLogs](vmui-overview.webp)
+<figcaption style="text-align: center; font-style: italic;">Overview pane in VMUI</figcaption>
+
+You can query your logs in the **Query** tab, found in `http://localhost:9428/select/vmui`. 
+You can filter streams on the left side pane to filter logs and use [LogsQL](https://docs.victoriametrics.com/victorialogs/logsql/) to search for entries. Note that logs will have `log_type` attached to them to distinguish between different types of logs.
