Description

Introduction

This course is designed for developers, administrators, and DevOps engineers who want to become proficient with the OpenShift Command Line Interface (CLI), known as oc. The CLI offers powerful capabilities for managing and automating tasks in OpenShift clusters. You’ll learn to create projects, deploy apps, scale resources, inspect logs, and perform essential cluster operations—all from the terminal.

Prerequisites

• Basic understanding of OpenShift or Kubernetes concepts (pods, deployments, services)

• Familiarity with terminal/command-line usage

• oc CLI installed and configured (e.g., using CRC or OpenShift sandbox)
