Ultra-focused learning series combining practical challenges, concise theory, and visual explanations. Each path helps you build or sharpen a specific skill, such as working with Linux storage, running containers, or building images.
Start by learning how to limit process resources in Linux using cgroups—from the most basic, hands-on cgroupfs manipulation to the more convenient systemd-run command. Then, explore how Docker and Kubernetes leverage cgroups to control the resource usage of containers and pods.
Four hands-on challenges covering the full storage stack. Start with emptyDir, move to dynamic provisioning with StorageClass, explore static PV binding patterns including label selectors, bidirectional claimRef, and topology-aware local volumes, then finish with PV reclaim policies and data recovery.
Nine hands-on challenges split into two sections. The resource section covers how requests, QoS classes, priority, and namespace quotas shape scheduling decisions. The placement section covers how affinity, topology spread, and dedicated nodes control where pods land. HPA closes the path by showing how requests drive autoscaling.
Master database management on Kubernetes with KubeBlocks! This path covers setup, auto-tuning, deployment, upgrades, backups, monitoring, and optimization across five tutorials, all aligned with Operator Capability levels.
