Upgrade aplikace Service Fabric

Tento ukázkový skript upgraduje spuštěnou instanci aplikace Service Fabric na verzi 1.3.0. Skript zkopíruje nový balíček aplikace do úložiště imagí clusteru, zaregistruje typ aplikace a odebere nepotřebný balíček aplikace. Skript spustí monitorovaný upgrade a průběžně kontroluje stav upgradu, dokud se upgrade neskončí nebo se nevrátí zpět. Podle potřeby upravte parametry.

V případě potřeby nainstalujte modul PowerShellu pro Service Fabric se sadou Service Fabric SDK.
