Getting Started with Red Hat OpenShift Container Platform for Developers

Introduction

As organizations move toward cloud-native development, developers are expected to build applications that are scalable, reliable, and fast to deploy. Red Hat OpenShift Container Platform is designed to simplify this process. Built on Kubernetes, OpenShift provides developers with a robust platform to deploy and manage containerized applications — without getting bogged down in infrastructure details.

In this blog, we’ll explore the architecture, key terms, and how you, as a developer, can get started on OpenShift — all without writing a single line of code.

What is Red Hat OpenShift?

OpenShift is an enterprise-grade container application platform powered by Kubernetes. It offers a developer-friendly experience by integrating tools for building, deploying, and managing applications seamlessly. With built-in automation, a powerful web console, and enterprise security, developers can focus on building features rather than infrastructure.

Core Concepts and Terminology

Here are some foundational terms that every OpenShift developer should know:

Project: A workspace where all your application components live. It's similar to a folder for organizing your deployments, services, and routes.

Pod: The smallest unit in OpenShift, representing one or more containers that run together.

Service: A stable access point to reach your application, even when pods change.

Route: A way to expose your application to users outside the cluster (like publishing your app on the web).

Image: A template used to create a running container. OpenShift supports automated image builds.

BuildConfig and DeploymentConfig: These help define how your application is built and deployed using your code or existing images.

Source-to-Image (S2I): A unique feature that turns your source code into a containerized application, skipping the need to manually build Docker images.

Understanding the Architecture

OpenShift is built on several layers that work together:

Infrastructure Layer

Runs on cloud, virtual, or physical servers.

Hosts all the components and applications.

Container Orchestration Layer

Based on Kubernetes.

Manages containers, networking, scaling, and failover.

Developer Experience Layer

Includes web and command-line tools.

Offers templates, Git integration, CI/CD pipelines, and automated builds.

Security & Management Layer

Provides role-based access control.

Manages authentication, user permissions, and application security.

Setting Up the Developer Environment (No Coding Needed)

OpenShift provides several tools and interfaces designed for developers who want to deploy or test applications without writing code:

✅ Web Console Access

You can log in to the OpenShift web console through a browser. It gives you a graphical interface to create projects, deploy applications, and manage services without needing terminal commands.

✅ Developer Perspective

The OpenShift web console includes a “Developer” view, which provides:

Drag-and-drop application deployment

Built-in dashboards for health and metrics

Git repository integration to deploy applications automatically

Access to quick-start templates for common tech stacks (Java, Node.js, Python, etc.)

✅ CodeReady Containers (Local OpenShift)

For personal testing or local development, OpenShift offers a tool called CodeReady Containers, which allows you to run a minimal OpenShift cluster on your laptop — all through a simple installer and user-friendly interface.

✅ Preconfigured Templates

You can select application templates (like a basic web server, database, or app framework), fill in some settings, and OpenShift will take care of deployment.

Benefits for Developers

Here’s why OpenShift is a great fit for developers—even those with minimal infrastructure experience:

🔄 Automated Build & Deploy: Simply point to your Git repository or select a language — OpenShift will take care of the rest.

🖥 Intuitive Web Console: Visual tools replace complex command-line tasks.

🔒 Built-In Security: OpenShift follows strict security standards out of the box.

🔄 Scalability Made Simple: Applications can be scaled up or down with a few clicks.

🌐 Easy Integration with Dev Tools: Works well with CI/CD systems and IDEs like Visual Studio Code.

Conclusion

OpenShift empowers developers to build and run applications without needing to master Kubernetes internals or container scripting. With its visual tools, preconfigured templates, and secure automation, it transforms the way developers approach app delivery. Whether you’re new to containers or experienced in DevOps, OpenShift simplifies your workflow — no code required.
