**Introduction**  
OpenShift is a powerful Kubernetes-based platform designed to accelerate the development, deployment, and management of containerized applications. Built by Red Hat, it provides developers with self-service capabilities while giving IT teams the tools to ensure security, compliance, and operational efficiency.

Organizations can use OpenShift for:

- **Developing modern applications** with built-in CI/CD pipelines.
- **Streamlining DevOps workflows** by standardizing Kubernetes-based infrastructure.
- **Managing hybrid or multi-cloud environments** with ease and scalability.

If you’re looking to deploy OpenShift on-premises using Red Hat Enterprise Linux, follow the steps below to set up your cluster.

### **Prerequisites**

1. **Hardware Requirements** (minimum):

2. **Software Requirements** :

3. **Download OpenShift Components** :

4. **Networking Requirements** :

* * *

### **Step 1: Prepare RHEL on All Nodes**

1. **Update Your System** :  
Ensure all nodes are running the latest updates.

2. **Install Required Packages** :

3. **Enable NTP for Time Synchronization** :

4. **Disable Swap** (required for Kubernetes):

5. **Enable Kernel Modules** :

6. **Configure Firewall Rules** :
