Build your home data center using Docker Swarm Mode!

This article provides a detailed overview of the complete process and core concepts for building a Docker Swarm cluster. First, by configuring hostnames, installing Docker, and initializing the Swarm cluster, it addresses Overlay Network compatibility issues in vSphere environments, successfully establishing a highly available architecture with either one manager and two workers or all managers. Next, it deploys the open-source graphical interface Swarmpit for intuitive cluster state management and provides an in-depth analysis of the hierarchical relationships and interaction logic among Stack, Service, Task, Node, Volume, and Network. The article offers command-line management tips for these core resources, including deployment, monitoring, log viewing, and node maintenance operations. Finally, it demonstrates how to quickly deploy real-world business applications using YAML files, introduces solutions for implementing automated HTTPS with Caddy and building shared storage with GlusterFS, and provides a Systemd service script to ensure nodes automatically come online after a reboot, offering comprehensive and practical guidance for container orchestration in production environments.
