What’s Actually Running in My Homelab? (50+ Self-Hosted Services)

Key Takeaways

• The homelab infrastructure is built on Proxmox for virtualization and TrueNAS for storage, with Kubernetes clusters managed by Rancher for orchestration of services.
• Network segmentation is achieved using three primary VLANs (IoT, Main, Cameras) plus a management network, enhancing security by isolating different device types.
• High availability is prioritized at the service level (e.g., HA Postgres with Patroni) rather than relying on Proxmox's HA features for VMs and LXCs.
• Certain high-traffic or public-facing services, like the documentation site, have been moved to a colocation facility for better performance and reliability.
• TrueNAS Scale is now the primary platform for internal applications, leveraging Docker Compose and ZFS for data management, snapshots, and local data access.
• The decision between Docker Compose on TrueNAS for home services and Kubernetes in colocation for public services is based on the intended use and exposure of the application.
• Data management on TrueNAS emphasizes ZFS features like snapshots, quick reverts, and offsite replication, applied consistently across both data and application storage.
• The homelab utilizes a layered approach, with Proxmox and TrueNAS forming the base, Kubernetes for orchestration, and specific applications running on top, all within a segmented network.
