Self-host Immich: I measured what Google Photos replacement actually costs in RAM

Описание и применение

Самостоятельный хостинг Immich требует более 4 ГБ свободной оперативной памяти и ~5 ГБ диска. При запуске стек использует ~2,4 ГБ RAM, а ML‑поиск работает на CPU за 2,2 с. Удаление сервиса ML экономит память, но убирает поиск и распознавание лиц.

Задача

Deploying a self-hosted Google Photos replacement that requires significant RAM and disk, making it unsuitable for low-resource environments.

Результат

Immich’s total working set is ~2.4 GB RAM (server 962 MB, ML 928 MB, Postgres 465 MB, Valkey 14 MB). Disk usage for 5 photos is 4.7 GB. ML search runs on CPU in ~2.2 s. The stack requires 4 GB+ free RAM and ~5 GB disk before photos, making it unsuitable for very small VPS or free-tier PaaS options.

Рабочий процесс

• Download official docker‑compose.yml and example.env from Immich releases
• Edit .env: set DB_PASSWORD to an alphanumeric value, set TZ, and set UPLOAD_LOCATION to a large disk
• Run docker compose up -d to pull images (~4.7 GB) and start containers
• Create admin account via http://localhost:2283 and complete onboarding
• Upload photos via API or mobile backup
• Use ML smart search and face recognition features

Доказательства

Immich is a four-container stack that wants gigabytes.

Special characters in DB_PASSWORD break the connection string — the env file warns you; believe it.
