Service Fabric uygulamasını yükseltme

Bu örnek betik, çalışan bir Service Fabric uygulama örneğini 1.3.0 sürümüne yükseltir. Betik, yeni uygulama paketini küme görüntü deposuna kopyalar, uygulama türünü kaydeder ve gereksiz uygulama paketini kaldırır. Betik izlenen bir yükseltme başlatır ve yükseltme tamamlanana veya geri dönene kadar yükseltme durumunu sürekli denetler. Parametreleri gereken şekilde özelleştirin.

Gerekirse, Service Fabric SDK’sı ile Service Fabric PowerShell modülünü yükleyin.
