- This intensive training offers a deep dive into the operational intricacies of Red Hat OpenShift, empowering IT professionals to confidently manage and maintain enterprise-grade Kubernetes environments. Moving beyond theoretical concepts, the curriculum is meticulously crafted to mirror real-world administrative challenges faced daily by organizations leveraging containerization. Participants will engage with a robust, interactive lab environment, providing unparalleled opportunities to implement, troubleshoot, and optimize OpenShift clusters from the ground up. The course emphasizes best practices for ensuring high availability, security, and scalability, critical for modern application delivery. Itβs an essential journey for those looking to master the leading hybrid cloud application platform.
- Requirements / Prerequisites
- Familiarity with Linux: Strong command-line proficiency on a Linux operating system is essential.
- Container Basics: A foundational understanding of container technology, Docker, or Podman concepts.
- Networking Fundamentals: Knowledge of IP addressing, DNS resolution, routing, and basic firewall rules.
- YAML/JSON Comprehension: Ability to read and understand configuration files written in YAML or JSON.
- Command-line Tools: Experience using common CLI tools for system administration tasks.
- Skills Covered / Tools Used
- OpenShift Cluster Provisioning: Explore various deployment strategies, including installer-provisioned infrastructure (IPI) on cloud platforms like AWS, Azure, and GCP, alongside user-provisioned infrastructure (UPI) for custom environments. Learn to prepare host systems and execute installation processes for robust, production-ready clusters.
- Core Platform Management: Master the
ocCLI for daily operations, manage OpenShift projects, user accounts, and group permissions with Role-Based Access Control (RBAC). Understand OpenShift’s internal registry and ImageStreams for consistent image management. - Advanced Application Deployment: Dive into sophisticated deployment patterns, including blue/green and canary deployments facilitated by Routes and Services. Leverage Operators from the OperatorHub to automate the lifecycle management of complex stateful applications.
- Persistent Storage Solutions: Configure and manage Persistent Volumes (PVs) and Persistent Volume Claims (PVCs) using various StorageClasses. Integrate OpenShift with external storage systems like NFS, Ceph Rados Block Device (RBD), and cloud-provider-specific CSI drivers (e.g., AWS EBS, Azure Disk) to support stateful workloads.
- Network Configuration & Policies: Gain expertise in OpenShift Software-Defined Networking (SDN), including OVN-Kubernetes and Open vSwitch. Implement granular network segmentation and isolation using NetworkPolicies, and configure Ingress Controllers for external application access.
- Security & Compliance: Enforce robust security postures with Security Context Constraints (SCCs), manage secrets and ConfigMaps securely, and integrate OpenShift with external identity providers (LDAP, OAuth) for streamlined user authentication.
- Monitoring, Logging & Alerting: Set up comprehensive cluster monitoring using OpenShift’s integrated Prometheus and Grafana stacks. Configure centralized logging with the EFK (Elasticsearch, Fluentd, Kibana) stack to analyze application and cluster events, and establish proactive alerting mechanisms.
- Resource Optimization & Scaling: Implement intelligent resource management with Quotas and LimitRanges. Configure Horizontal Pod Autoscalers (HPA) for demand-driven scaling and understand the principles behind Cluster Autoscaling for infrastructure elasticity.
- Troubleshooting & Diagnostics: Develop systematic approaches to diagnose and resolve common OpenShift operational issues. Utilize
oc debug, event logs, and metric data to pinpoint root causes and restore service efficiently. - Automation with OpenShift Pipelines: Introduction to OpenShift Pipelines (based on Tekton) for building robust CI/CD workflows, enabling automated application builds, testing, and deployments directly within the OpenShift ecosystem.
