Mulai Cepat: Membuat Azure Firewall dengan beberapa alamat IP publik - Bicep

Dalam mulai cepat ini, Anda menggunakan file Bicep untuk menyebarkan Azure Firewall dengan beberapa alamat IP publik dari awalan alamat IP publik. {i>Firewall

Diagram memperlihatkan konfigurasi jaringan untuk mulai cepat ini.

Bicep adalah bahasa pemrogram khusus domain (DSL) yang menggunakan sintaks deklaratif untuk menyebarkan sumber daya Azure. Bicep menyediakan sintaks ringkas, keamanan jenis yang andal, dan dukungan untuk penggunaan kembali kode. Bicep menawarkan pengalaman penulisan terbaik untuk solusi infrastructure-as-code di Azure.

Untuk informasi selengkapnya tentang Azure Firewall dengan beberapa alamat IP publik, lihat Menerapkan Azure Firewall dengan beberapa alamat IP publik menggunakan Azure PowerShell.

Beberapa sumber daya Azure yang ditentukan dalam templat:

Menerapkan file Bicep

  1. Simpan file Bicep sebagai main.bicep ke penyimpanan lokal komputer Anda.

  2. Sebarkan file Bicep menggunakan Azure CLI atau Azure PowerShell.

    az group create --name exampleRG --location eastus
    az deployment group create --resource-group exampleRG --template-file main.bicep --parameters adminUsername=<admin-username>
    

    Catatan

    Ganti <nama pengguna admin> dengan nama pengguna admin untuk server backend.

    Anda akan diminta untuk memasukkan kata sandi admin.

    Setelah penyebaran selesai, Anda akan melihat pesan yang menunjukkan penyebaran berhasil.

Memvalidasi penyebaran

Di portal Microsoft Azure, tinjau sumber daya yang diterapkan. Perhatikan alamat IP publik {i>firewall

Gunakan Sambungan Desktop Jauh untuk tersambung ke alamat IP publik {i>firewall.

Membersihkan sumber daya

Jika Anda tidak lagi membutuhkan sumber daya yang Anda buat dengan {i>firewallfirewall

Untuk menghapus grup sumber daya tersebut, hubungi Remove-AzResourceGroup cmdlet:

Remove-AzResourceGroup -Name "exampleRG"
