Core Concepts

The cluster is organized: Sites → Nodes → Containers

• Users & Groups — Accounts, groups, LDAP authentication
• Sites — Network configuration, DHCP, DNS
• External Domains — Public domains with automatic SSL/TLS
• Nodes — Proxmox VE servers within a site
• Containers — LXC instances on nodes (user guide)

Setup order: Users & Groups → Sites → External Domains (optional) → Nodes → Containers
