Longhorn In Action: A Mini Course on Kubernetes Storage Solutions

Video Description

📌 Welcome to "Longhorn in Action: A Mini Course on Kubernetes Storage Solutions"! In this hands-on tutorial, we'll walk you through everything you need to know about using Longhorn to manage persistent storage on Kubernetes. This mini-course will cover everything from architecture to backup and restore scenarios for real-world applications. First, we dive into Longhorn's architecture to understand how it works in a Kubernetes environment. Next, we walk through the installation of Longhorn on a live Kubernetes cluster. Afterward, we set up a real application with Longhorn volumes, and get familiar with essential features that Longhorn offers, such as: Replicas: How to manage and update volume replicas for redundancy. Data Locality: Ensuring data is placed efficiently to reduce latency. Replica Auto Balance: Automatically distributing replicas across the cluster. Snapshot Data Integrity: Protecting the integrity of your data through snapshots. Trim Filesystem: Improving storage efficiency by trimming unused blocks in the filesystem. Node/Disk/Zone Level Soft Anti-Affinity: Optimizing volume placement for fault tolerance. Finally, we dive into a real-world backup and restore scenario, where we simulate data destruction and then restore it from a Longhorn volume backup, showcasing Longhorn's powerful backup and restore capabilities. --- ⏰ Timestamps for Easy Navigation: 00:00 Overview of Longhorn Architecture 03:51 Installing Longhorn on Kubernetes Cluster 12:55 Setting Up a Real Application with Persistent Volumes 19:13 Updating Volume Replicas 21:44 Understanding Data Locality in Longhorn Volumes 23:10 Understanding Snapshot Data Integrity in Longhorn Volumes 25:17 Understanding Replicas Auto Balance in Longhorn Volumes 27:30 Understanding Trimming in Longhorn Volumes 28:42 Understanding Node/Disk/Zone Level Soft Anti-Affinity in Longhorn Volumes 32:22 Backup and Restore with Longhorn: A Real-World Scenario --- 📌 Subscribe to CodeOpsByMo for more hands-on DevOps tutorials. 👍 Like the video if you found it helpful, and let us know your thoughts in the comments!
