Meningkatkan aplikasi Service Fabric

Skrip sampel ini meningkatkan instans aplikasi Service Fabric yang berjalan ke versi 1.3.0. Skrip menyalin paket aplikasi baru ke penyimpanan gambar kluster, mendaftarkan jenis aplikasi, dan menghapus paket aplikasi yang tidak perlu. Skrip memulai pemutakhiran yang dipantau dan terus memeriksa status pemutakhiran hingga pemutakhiran selesai atau kembali bergulir. Sesuaikan parameter sesuai kebutuhan.

Jika diperlukan, instal modul Service Fabric PowerShell dengan SDK Service Fabric.
