The document provides a detailed guide on setting up a Docker Swarm cluster with Multidimensional Scaling (MDS) using Couchbase services across multiple nodes. It explains how to initiate three Ubuntu instances on EC2, configure Docker with experimental features, and assign specific labels to each node to optimize resource allocation for different Couchbase services, such as Index, Data, and Query. The guide further describes enabling Swarm Mode, creating a cluster with one manager and two worker nodes, and deploying Couchbase services with constraints that match the labels assigned to each node. It concludes with verifying the successful distribution of services across the nodes, ensuring each service runs on the appropriate host, thereby providing a comprehensive database solution for various applications.
