The document discusses using Gluster Storage to provide storage for containerized applications in a Kubernetes cluster. It outlines the challenges of replatforming an ecommerce site to use open source technologies, applying RAS(S) principles, and having a scalable and fault-tolerant solution. The plan is to use Docker containers, Kubernetes for orchestration, and GlusterFS storage. GlusterFS provides highly available, replicated storage across all Kubernetes nodes to support the storage needs of containerized applications.

3. Our story...

4. The Challenge
To re-platform our existing Ecommerce website from .NET to Java.

5. The Direction
• Use open source technologies
• Apply principles of the RAS(S) model
• Scalable solution
• Eliminate single points of failure
• Automate, automate, automate
RAS(S) model
• Reliable
• Available
• Serviceable
• (Secure)

6. The Plan
• Multiple tiered environment
• Containerized applications in all layers
• Use Docker as the container format
• Kubernetes for Docker orchestration
• Jenkins for continuous integration & deployment

7. Storage Requirements
• Highly available
• Replicated data
• Redundant mount paths
• Available across all nodes in a Kubernetes cluster
• Supported in Docker containers
• Simple to setup and maintain

8. Storage Architecture

9. Kubernetes Architecture
Technologies:
• Kubernetes
• Docker
• flanneld
• etcd
• HAProxy
• Keepalived
• GlusterFS

10. Gluster Storage Use Cases
• Presentation layer – Site optimization tools that cache static content to disk
allowing shared content across containers
• Caching layer – Cache session state data and persist the cache to disk
• Application layer – centralized application logging
