9	Assisted Installer	Bare metal, Edge, Disconnected	Simplified UI-based deployment	⚠️ Semi-automated	Via Red Hat Hybrid Cloud Console
10	Disconnected / Air-Gapped	On-prem, secure networks	Secure/regulated environments	⚠️ Manual + Mirroring	Requires local registry, image/catalog mirroring
11	Single Node OpenShift (SNO)	Bare metal or VM (single node)	Edge deployments, limited resource use cases	✅ Automated	All OpenShift services on one node (master, infra, and worker)

❓ Can you install and use OpenShift Container Platform (OCP) without buying it?

✅ Yes, you can install and use OCP temporarily without buying it, but with limitations.

---

🔓 Here’s how you can use OpenShift without buying it:

---

✅ 1. Use the 60-day Free Trial (OCP Evaluation License)

Red Hat allows you to:

• Install the full OpenShift Container Platform
• Use it for 60 days
• Get full access to features (like the web console, monitoring, operators, etc.)

👉 You need to:

• Register at Red Hat Customer Portal
• Download the installer
• Get a pull secret for access

🔗 Get started here

---

✅ 2. Use OKD (The Free & Open-Source Version of OCP)

Think of OKD as the “community edition” of OpenShift.

• It has most features of OpenShift
• 100% free and open source
• No license or subscription needed
• Great for learning, development, and testing

---

✅ 3. Use OpenShift Local (formerly CodeReady Containers)

A lightweight OpenShift cluster that runs on your laptop (single-node)

• Good for learning and testing
• Works on Linux, macOS, Windows
• Also requires a pull secret, but it’s free to use

🔗 OpenShift Local

---

⚠️ Limitations if you don’t pay:

Option	Limitation
OCP Trial	60 days, after which support and access may stop
OKD	No official Red Hat support or enterprise features
OpenShift Local	Single-node only, limited to ~8GB RAM, dev use only

---

🏁 Conclusion

Use Case	Recommended Option
Learn & experiment	✅ OKD or OpenShift Local
Short-term evaluation	✅ OCP 60-day Trial
Production / Enterprise	❌ Need paid subscription to Red Hat OCP

Here is a comprehensive list of deployment methods for OpenShift, covering both OpenShift Container Platform (OCP) and OpenShift OKD (community version):

---

🧩 1. Installer-Provisioned Infrastructure (IPI)

• Description: Red Hat OpenShift installer provisions the infrastructure and installs OpenShift.
• Best for: Automated deployment in supported cloud environments.
• Supported Platforms:
  • AWS
  • Azure
  • GCP
  • vSphere (full stack automation)
• Use Case: Quick start in production or staging with minimal manual setup.

---

🧱 2. User-Provisioned Infrastructure (UPI)

• Description: User manually provisions the infrastructure; OpenShift is installed on top.
• Best for: Customized infrastructure setups or unsupported cloud/on-prem environments.
• Supported Platforms:
  • Bare metal
  • OpenStack
  • VMware vSphere
  • Cloud platforms with manual setup (AWS, Azure, etc.)
• Use Case: When infrastructure needs full control and customization.

---

🧪 3. OpenShift Local (Formerly CodeReady Containers)

• Description: Single-node OpenShift cluster for local development.
• Best for: Developers testing or building apps locally.
• Platform:
  • Windows
  • macOS
  • Linux
• Use Case: Lightweight, personal development environments.

---

🧪 4. OKD (The Community Distribution of Kubernetes for OpenShift)

• Description: Open-source version of OpenShift (upstream for OCP).
• Deployment:
  • OKD IPI/UPI (similar to OCP)
  • OpenShift on Bare Metal using Fedora CoreOS
• Use Case: Community, testing, or cost-sensitive environments.

---

☁️ 5. OpenShift Dedicated (SaaS)

• Description: Fully-managed OpenShift clusters by Red Hat.
• Platform:
  • AWS
  • GCP
• Use Case: Enterprises wanting managed Kubernetes without managing infrastructure.

---

☁️ 6. Azure Red Hat OpenShift (ARO)

• Description: Jointly managed OpenShift offering by Microsoft and Red Hat.
• Platform: Microsoft Azure
• Use Case: Native Azure integration with OpenShift.

---

🧠 7. Red Hat OpenShift Service on AWS (ROSA)

• Description: Managed OpenShift on AWS, jointly operated by AWS and Red Hat.
• Use Case: Seamless OpenShift and AWS ecosystem integration.

---

🏭 8. OpenShift on IBM Cloud

• Description: Managed OpenShift clusters on IBM Cloud.

🔁 9. Assisted Installer (for Bare Metal & Hybrid)

• Description: UI/UX based assisted deployment of OpenShift via the Red Hat Hybrid Cloud Console.
• Use Case: Easier deployment for edge, bare metal, and disconnected environments.

---

🚢 10. Disconnected / Air-Gapped Deployment

• Description: Deploy OpenShift in environments without internet access.
