Run Docker containers inside Proxmox LXC with full performance. Covers nesting, overlay2 on ZFS, privileged vs unprivileged tradeoffs, cgroup resource limits, and security hardening for production homelab workloads.
Configure Docker logging drivers, set up log rotation limits, and deploy a centralized log pipeline with Loki and Grafana Alloy. Practical configurations to prevent disk-full disasters and enable real-time container observability in your homelab.
Hardening systemd service units in your homelab isn’t just for production servers — it’s how you prevent one compromised service from taking down your entire host. This guide covers sandboxing, capability drops, filesystem isolation, and resource limits with real unit files you can use today.
Set deterministic ZFS ARC limits, add L2ARC without wasting RAM on metadata, and tune recordsize and compression for your Proxmox homelab VMs.
Complete Proxmox VE PCIe passthrough guide — GPU for Jellyfin transcoding, NVMe direct access, SAS HBA for NAS VMs. Kernel configs, vfio-pci, IOMMU groups, and working Proxmox VM settings.
Practical Docker container resource limits guide for homelabs — CPU quota/pinning, memory hard/soft limits, swap control, block I/O throttling, cgroup v2 differences, and Docker Compose examples.
Complete Linux sysctl kernel tuning guide for homelab servers. Network buffers, BBR congestion control, OOM management, fs.inotify limits, and Docker-specific sysctl configs.
Docker Hub rate-limits anonymous pulls to 100 per 6 hours (200 for authenticated users). In a homelab with frequent rebuilds, multiple hosts, or CI-style workflows, you’ll hit that limit fast. Even if you don’t, pulling the same nginx:alpine image ten times across ten containers wastes bandwidth and time. A local Docker registry mirror fixes both: it acts as a pull-through cache. First pull is from Docker Hub (or any upstream). Every subsequent pull from any host in your lab hits the local cache instead. ...
