Ich habe festgestellt, dass die Installation von Pandas und Numpy (Abhängigkeit) in einem Docker-Container unter Verwendung des Basisbetriebssystems Alpine vs. CentOS oder Debian viel länger dauert. Ich habe unten einen kleinen Test erstellt, um den Zeitunterschied zu demonstrieren. Abgesehen von den wenigen Sekunden, die Alpine benötigt, um die Build-Abhängigkeiten für die Installation von Pandas und Numpy zu aktualisieren und herunterzuladen, warum dauert die Datei setup.py etwa 70-mal länger als bei der Installation von Debian?
Gibt es eine Möglichkeit, die Installation mit Alpine als Basis-Image zu beschleunigen, oder gibt es ein anderes Basis-Image von vergleichbarer Größe wie Alpine, das für Pakete wie Pandas und Numpy besser geeignet ist?
