将 WEBSITE_CONTENTAZUREFILECONNECTIONSTRING 设置为防火墙后的存储时,具有 VNet 集成的函数应用部署失败
Function App with VNet Integration Failing Deployment When Setting WEBSITE_CONTENTAZUREFILECONNECTIONSTRING to Storage Behind Firewall
部署以下 ARM 模板:虚拟网络、网络安全组、存储帐户、应用服务计划、功能应用
当省略 WEBSITE_CONTENTAZUREFILECONNECTIONSTRING
和 WEBSITE_CONTENTSHARE
的设置(注释掉)时,部署成功但函数应用程序配置显示警告。
启用这两个设置时,部署失败并显示 403 禁止消息。

我在 NSG 上尝试过多种设置,添加服务标签,允许 IP 与函数应用相关联。我还尝试在存储帐户防火墙上允许 IPRules。唯一有效的设置是使用 'Allow access from all networks' 完全禁用存储帐户防火墙,这对于网络来说是不可接受的设置。

部署到现有资源组的命令:

解决方案是添加另一个名为 WEBSITE_CONTENTOVERVNET

。
