VCPKG_OFFLINE_STRATEGY
Stand: 26. Dezember 2025
Version: v1.3.1
Kategorie: π Deployment
Plattformen: Windows, Linux, Docker, ARM/Raspberry Pi
ThemisDB nutzt vcpkg mit einer Offline-First Strategie fΓΌr reproduzierbare, netzwerk-unabhΓ€ngige Builds auf allen Plattformen.
β
Offline-fΓ€hig: Builds ohne Internet nach initialem Setup
β
Reproduzierbar: Identische Binaries durch versionierte Baseline
β
Schnell: ~50% schnellere Builds (keine Downloads)
β
CI/CD-ready: Cache zwischen Build-Agents teilbar
β
Air-Gapped: Enterprise/Government Compliance
β
Cross-Platform: Identischer Workflow fΓΌr Windows/Linux/ARM

# 2. Manifest-Mode: Dependencies analysieren
vcpkg install --triplet x64-windows --dry-run
# 3. Source-Archive herunterladen (ohne Build)
vcpkg x-download openssl rocksdb boost-asio boost-beast simdjson tbb arrow hnswlib ...
# 4. Multi-Triplet Support

}
# 5. Verifikation
Write-Host "β
vcpkg offline cache bereit: $(Get-ChildItem vcpkg/downloads | Measure-Object).Count Packages"Ergebnis:
-
vcpkg/downloads/enthΓ€lt ~130+ Source-Archive (~2.5 GB) - Alle zukΓΌnftigen Builds sind offline-fΓ€hig
- Cache kann zwischen Maschinen geteilt werden (USB/NAS/Git LFS)
# Windows
git clone https://github.com/makr-code/ThemisDB.git
cd ThemisDB
# vcpkg offline cache bereits im Repo (via Git LFS oder direkt committed)
# KEIN Internet nΓΆtig!
cmake -B build -DCMAKE_TOOLCHAIN_FILE=vcpkg/scripts/buildsystems/vcpkg.cmake
cmake --build build --config Release# GitHub Actions / GitLab CI
- name: Restore vcpkg cache
uses: actions/cache@v3
with:

key: vcpkg-downloads-${{ hashFiles('vcpkg.json') }}
- name: Build
run: |
cmake -B build -DCMAKE_TOOLCHAIN_FILE=vcpkg/scripts/buildsystems/vcpkg.cmake
cmake --build buildVorteil: Cache wird zwischen Runs wiederverwendet, ~10 Min Zeitersparnis.
# 1. Auf Maschine MIT Internet: Cache vorbereiten

- Empfohlen: 4+ GB RAM, SSD statt SD-Karte
Multi-Arch: linux/amd64, linux/arm64
# Nutzt vcpkg downloads/ als cache layer

RUN vcpkg install --triplet ${VCPKG_TRIPLET}Besonderheiten:
- Nur
downloads/in Image kopieren (~2.5 GB) - NICHT
packages/oderbuildtrees/kopieren - Multi-stage build spart ~8 GB Image-GrΓΆΓe
| Szenario | Mit Internet | Mit Cache | Ersparnis |
|---|---|---|---|
| Clean Build | 42 Min | 18 Min | 57% schneller |
| Rebuild | 38 Min | 15 Min | 61% schneller |
| CI Pipeline | 55 Min | 22 Min | 60% schneller |
| Build-Typ | Ohne Cache | Mit Cache | Ersparnis |
|---|---|---|---|
| Minimal | ~1.2 GB | 0 MB | 100% |
| LLM | ~1.8 GB | 0 MB | 100% |
| Full | ~2.5 GB | 0 MB | 100% |
# Nach vcpkg.json Γnderung: Neue Packages hinzufΓΌgen
.\scripts\update-vcpkg-cache.ps1
# Manuelle Verifikation
vcpkg x-download --dry-run# Unbenutzte Archive entfernen (spart ~500 MB)
.\scripts\cleanup-vcpkg-cache.ps1
# Kompletter Rebuild (bei Problemen)
Remove-Item -Recurse -Force vcpkg\buildtrees, vcpkg\packages
.\scripts\setup-vcpkg-offline.ps1# Binary cache aktivieren (experimentell)
$env:VCPKG_BINARY_SOURCES="clear;files,$PWD\vcpkg-binary-cache,readwrite"
# Erster Build: Erstellt binaries
cmake -B build -DCMAKE_TOOLCHAIN_FILE=vcpkg/scripts/buildsystems/vcpkg.cmake
cmake --build build
# Zweiter Build: Nutzt cached binaries (~5x schneller)
cmake -B build2 -DCMAKE_TOOLCHAIN_FILE=vcpkg/scripts/buildsystems/vcpkg.cmake
cmake --build build2Resultat: vcpkg-binary-cache/ (~600 MB komprimiert) kann geteilt werden.

Committe
vcpkg/downloads/ins Repository (Git LFS empfohlen) - Nutze identische vcpkg baseline fΓΌr alle Entwickler
- Teile Binary Cache im Team (Netzwerk-Share/S3)
- Aktiviere ccache (Linux) fΓΌr schnellere Rebuilds
- Verwende Docker Multi-Stage fΓΌr kleinere Images
-
Committe NICHT
vcpkg/packages/oderbuildtrees/(zu groΓ, platform-spezifisch) - Mixe NICHT verschiedene vcpkg-Versionen im Team
