🌐 Create an Internet-Accessible Managed OpenShift Cluster Using the Azure Portal
Azure Red Hat OpenShift (ARO) gives you a fully managed, enterprise-grade OpenShift cluster running natively on Microsoft Azure. It combines the power of OpenShift with the reliability and scalability of Azure—all while being supported jointly by Microsoft and Red Hat.
In this article, we’ll walk through how to create an internet-accessible OpenShift cluster using the Azure portal, and how to inspect the Azure resources that make it work behind the scenes.
🚀 What You'll Accomplish
🛠️ Prerequisites
Before you begin, make sure you have:
You don’t need to install the Azure CLI or OpenShift CLI for this walkthrough.
📦 Step 1: Create the ARO Cluster via Azure Portal
🌍 Access the OpenShift Console
Once deployed, go to the ARO cluster overview page in the Azure portal.
🔍 Inspecting Azure Resources Behind the Cluster
ARO provisions several Azure resources in the background. Here's what gets created:
1. Virtual Network and Subnets
2. Route Tables and Network Security Groups
3. Managed Resource Group
You should not modify resources in the managed group directly, as it's controlled by ARO.
4. Monitoring & Logs
🧠 Good to Know
✅ Summary
With just a few clicks, you can deploy a secure, highly available, internet-facing OpenShift cluster in Azure using ARO. It's fully managed, production-ready, and integrated with Azure services. By exploring the underlying resources, you gain better visibility into how OpenShift operates in the cloud.
