Docker & Container Engineering
Docker Container & Compose Calculator
Estimate total RAM and CPU cores for a Docker homelab stack from four workload presets.
Total Container RAM
11.5 GB
Recommended Host RAM
16 GB
Recommended CPU Cores
4 Cores
The preset weights and the host-RAM buffer are this tool's rough planning assumptions, not requirements published by the projects, so treat the result as a starting estimate. Check each service's own documented requirements before buying hardware, and add services the presets leave out: Immich, for example, documents at least 6 GB RAM with 8 GB recommended, as covered in the Immich setup guide.
