Introduction

OpenShift, developed by Global Horizon, It simplifies containerized applications' deployment, management, and scaling, making it easier for organizations to adopt and utilize container technology. This training program aims to equip participants with the essential skills and knowledge required to effectively administer OpenShift clusters, ensuring smooth application deployment, robust networking, efficient storage management, and comprehensive monitoring.

 

Methodologies

The training will follow a combination of interactive lectures, hands-on lab exercises, real-world scenarios, and demonstrations. Participants will have access to a dedicated OpenShift cluster for practice throughout the training, allowing them to gain practical experience in a controlled environment. The hands-on approach will enable participants to apply their learning in real-time, reinforcing key concepts and best practices.

 

Target Audience

This training program is designed for IT professionals, DevOps engineers, system administrators, and cloud administrators who have a foundational understanding of containerization, Kubernetes concepts, and basic command-line usage. Participants should be familiar with Linux operating systems and have experience working with containers and container orchestration technologies.

 

Objectives

By the end of this training program, participants will be able to:

  1. Explain the key features and benefits of OpenShift as a containerization platform.
  2. Install, configure, and manage OpenShift clusters in various deployment scenarios.
  3. Understand the core components of OpenShift and their roles in container orchestration.
  4. Deploy and manage applications using Pods, Deployments, and ReplicaSets.
  5. Implement effective networking and routing strategies to ensure seamless communication between applications.
  6. Set up and manage persistent storage for containerized applications using Persistent Volume Claims and Storage Classes.
  7. Use ConfigMaps and Secrets to manage application configurations securely.
  8. Leverage Operators to extend the functionality of OpenShift and automate complex tasks.
  9. Monitor the health and performance of OpenShift clusters using Prometheus and Grafana.
  10. Centralize log management for troubleshooting and analysis using Elasticsearch and Kibana.
