透過私人端點私下執行 Bicep 部署指令碼
使用 Microsoft.Resources/deploymentScripts
資源 API 版本 2023-08-01
,您可以在 Azure 容器執行個體 (ACI) 內私下執行部署指令碼。
設定環境
在此設定中,部署指令碼所建立的 ACI 會在虛擬網路內執行,並取得私人 IP 位址。 然後,其會透過私人端點建立與新的或預先存在的儲存體帳戶連線。 containerSettings/subnetIds
屬性會指定必須在虛擬網路子網路中部署的 ACI。
若要私下執行部署指令碼,您需要下列基礎結構,如架構圖所示:
- 建立具有兩個子網路的虛擬網路:
- 私人端點的子網路。
- 一個子網路用於 ACI,這個子網路需要
Microsoft.ContainerInstance/containerGroups
委派。
- 建立没有公用網路存取權的儲存體帳戶。
- 在使用儲存體帳戶上
file
子資源所設定的虛擬網路內建立私人端點。 - 建立私人 DNS 區域
privatelink.file.core.windows.net
,並將私人端點 IP 位址註冊為 A 記錄。 將私人 DNS 區域連結至建立的虛擬網路。 - 在儲存體帳戶上建立具有
Storage File Data Privileged Contributor
權限的使用者指派受控識別,並在部署指令碼資源的identity
屬性中指定該受控識別。 若要指派身分識別,請參閱身分識別。 - 部署指令碼資源會自動建立 ACI 資源。

ACI 會從 Microsoft Container Registry 下載容器映像。 如果您使用防火牆,請允許列出 URL mcr.microsoft.com 以下載映像。 無法下載容器映像會導致 ACI 進入 waiting
狀態,最終造成逾時錯誤。
