Curriculum
Module 1: Introduction to OpenShift & Container Fundamentals
This foundational module introduces the core concepts of Red Hat OpenShift and the principles of containerization. We'll explore what OpenShift is, its relationship to Kubernetes, and its value in enterprise environments. Lectures will cover Docker/Podman basics, creating and managing container images, understanding OCI standards, and an overview of OpenShift's unique features. You'll learn about Projects, Users, and Roles, and gain initial hands-on experience navigating the OpenShift Web Console and CLI.
Module 2: OpenShift Cluster Architecture & Components
Delve into the architectural blueprint of an OpenShift cluster. This section covers the master and worker nodes, control plane components like API Server, etcd, Scheduler, and Controller Manager, along with data plane elements such as Kubelet and Kube-proxy. Understand the role of Operators, CRI-O container runtime, and the underlying Linux operating system (CoreOS). We'll discuss the lifecycle of a pod and the interactions between different OpenShift services.
Module 3: Deploying & Managing Applications
Learn the practicalities of deploying and managing applications on OpenShift. This module details deploying applications using various methods: from existing images, source-to-image (S2I), and Helm charts. Topics include managing deployments, StatefulSets, DaemonSets, Jobs, and CronJobs. We'll cover scaling applications, rolling updates, rollbacks, and advanced deployment strategies like blue/green and canary deployments. Understanding application health checks and readiness probes is also a key focus.
Module 4: Networking in OpenShift
Master OpenShift's robust networking capabilities. This module explores internal and external networking, including the OpenShift SDN (Software-Defined Network), network policies, and understanding different SDN modes. You'll learn how to expose applications using Routes, Ingress, and Load Balancers. We'll also cover service discovery, DNS within the cluster, and managing network traffic for multi-tenant environments, ensuring secure and efficient communication.
Module 5: Storage Management
Address the critical aspect of persistent storage in OpenShift. This section covers various storage options, including Persistent Volumes (PVs), Persistent Volume Claims (PVCs), and Storage Classes. We'll explore dynamic provisioning, different storage backends (e.g., NFS, Ceph, iSCSI, cloud-provider specific storage), and best practices for attaching and managing storage for stateful applications, ensuring data durability and availability.
Module 6: Security & Access Control
Fortify your OpenShift clusters with comprehensive security measures. This module deep dives into OpenShift's security context constraints (SCCs), role-based access control (RBAC), and managing users and groups. We'll examine image security, vulnerability scanning, managing secrets, config maps, and integrating with external identity providers (LDAP, OAuth). Best practices for securing container images, namespaces, and overall cluster hardening are also covered.
Module 7: Monitoring, Logging & Troubleshooting
Equip yourself with the tools and techniques for effective monitoring, logging, and troubleshooting. Learn to leverage OpenShift's integrated monitoring stack (Prometheus, Grafana) for cluster and application metrics. We'll explore logging solutions (Elasticsearch, Fluentd, Kibana - EFK stack) for centralized log collection and analysis. This module also provides practical strategies for diagnosing and resolving common OpenShift cluster and application issues.
Module 8: Scaling & Resource Management
Optimize resource utilization and ensure application performance through intelligent scaling. This section covers horizontal pod autoscaling (HPA) and cluster autoscaling. We'll discuss resource quotas, limit ranges, and managing compute resources (CPU, memory) for pods and containers. Understand how to design for high availability, fault tolerance, and implement effective resource governance policies across your OpenShift environment.
Module 9: Cluster Maintenance & Upgrades
Understand the operational aspects of maintaining a healthy OpenShift cluster. This module covers node management, backing up and restoring etcd, and performing routine maintenance tasks. We'll also delve into the process of upgrading OpenShift clusters, patch management, and ensuring minimal downtime during operational procedures. Best practices for disaster recovery and business continuity are also discussed.
Module 10: OpenShift Certification Preparation & Practice
