Course Overview
Welcome to Kubernetes Storage (K8S-STO-106): 1500 Questions, an unparalleled, intensive deep-dive into the complex world of data persistence within cloud-native environments. This course is meticulously designed to transform your understanding from foundational concepts to expert-level mastery, focusing exclusively on the critical aspects of Kubernetes storage. Unlike typical instructional programs, K8S-STO-106 challenges learners with 1500 diverse questions, scenarios, and problem-solving exercises, ensuring a robust, hands-on learning experience that solidifies knowledge and builds practical troubleshooting acumen. You will embark on a comprehensive journey to master persistent volumes, persistent volume claims (PVCs), and the indispensable Container Storage Interface (CSI) drivers, which are the backbone of modern Kubernetes storage solutions. The curriculum extensively covers dynamic provisioning, allowing you to automate storage allocation efficiently, alongside vital data protection strategies including robust backup solutions, snapshot capabilities, and advanced recovery techniques. This course is not just about understanding storage components; it’s about architecting, implementing, and, crucially, troubleshooting resilient storage infrastructures for your applications running on Kubernetes.The “1500 Questions” methodology underpins the entire course, offering a unique pedagogical approach that moves beyond passive learning. Each question and its accompanying solution or discussion are crafted to expose you to real-world challenges, corner cases, and best practices, pushing you to think critically and apply your knowledge in various simulated environments. This intensive format prepares you not only for technical certifications but, more importantly, for the practical demands of managing production-grade Kubernetes clusters. From understanding the nuances of different storage classes to diagnosing elusive volume attachment issues, you will gain the confidence to handle any storage-related obstacle. This course specifically aims to equip you, as one of the 15 focused students, with an exhaustive skill set in managing application data lifecycle, ensuring high availability, data integrity, and performance across diverse storage backends.
Requirements / Prerequisites
To maximize your learning experience in K8S-STO-106, a foundational understanding of Kubernetes core concepts is essential. This includes familiarity with fundamental objects such as Pods, Deployments, Services, and Namespaces, as well as a basic grasp of how applications are deployed and managed within a Kubernetes cluster. Proficiency with the Linux command line interface (CLI) is a non-negotiable requirement, as much of the interaction with Kubernetes and its underlying infrastructure occurs via `kubectl` and other command-line tools. A basic understanding of networking concepts, including IP addresses, ports, and DNS, will also be beneficial when troubleshooting connectivity issues between pods and storage targets. While not strictly mandatory, prior exposure to a cloud provider (e.g., AWS, GCP, Azure) or experience with virtualized environments will provide a useful context for understanding various storage backend integrations. Most importantly, a strong willingness to engage with challenging problems and to learn through extensive practice is crucial, given the course’s question-intensive format.
Skills Covered / Tools Used
- Core Kubernetes Storage APIs: In-depth understanding and practical application of PersistentVolume (PV), PersistentVolumeClaim (PVC), and StorageClass resources for declaring, requesting, and provisioning storage.
- Container Storage Interface (CSI) Drivers: Comprehensive knowledge of the CSI specification, deploying and managing various CSI drivers for different storage technologies, including cloud-provider specific drivers (e.g., AWS EBS CSI, Azure Disk CSI, GCE PD CSI), network file systems (NFS), iSCSI, and distributed storage solutions like Ceph/Rook.
- Dynamic Storage Provisioning: Mastering the configuration and utilization of StorageClasses to automate volume creation based on specific performance, access mode, and retention policies, significantly streamlining storage operations.
- Static Storage Provisioning: Understanding scenarios where manual PV creation is necessary, and effectively managing the lifecycle of statically provisioned volumes.
- Volume Management Operations: Performing crucial administrative tasks such as online and offline volume expansion, resizing existing volumes, managing volume deletion policies, and understanding volume reclaim strategies.
- Data Protection and Recovery: Implementing robust backup and restore strategies for Kubernetes applications using tools like Velero, Kasten K10, or custom scripting solutions. Gaining proficiency in creating and managing Kubernetes volume snapshots for point-in-time recovery.
- Advanced Storage Concepts: Exploring specialized topics like local persistent volumes, topology-aware volume provisioning, volume populators, and understanding the implications of shared storage solutions in a Kubernetes context.
- Troubleshooting Kubernetes Storage: Developing expert-level diagnostic skills for identifying and resolving common and complex storage-related issues, utilizing `kubectl describe`, `kubectl logs`, event monitoring, and understanding underlying storage system logs.
- Performance Optimization: Learning to benchmark storage performance, understand metrics like IOPS, latency, and throughput, and make informed decisions on storage class selection and configuration for optimal application performance.
- Security Best Practices: Implementing access control (RBAC) for storage operations, understanding storage encryption at rest and in transit, and securing sensitive data within persistent volumes.
- Tools Utilized: Extensive use of `kubectl` for all Kubernetes interactions, specific CSI driver command-line interfaces, Velero CLI for backup/restore, cloud provider CLIs (e.g., `aws cli`, `gcloud`), and potentially Prometheus/Grafana for monitoring storage metrics.
