通过 ARM 模板部署时的 Azure 函数暂存槽交换错误答案

【问题标题】：Azure function staging slot swap bug when deployed via ARM template通过 ARM 模板部署时的 Azure 函数暂存槽交换错误
【发布时间】：2018-08-22 04:38:15
【问题描述】：

我使用 ARM 模板创建了一个 Azure 函数应用（消费计划）。在我部署代码并执行交换操作（VSTS 任务）后，生产槽和暂存槽都有新代码。但是我希望在交换操作之后暂存槽有旧代码，这是 Azure 函数中的一个已知错误吗？还是我需要做任何额外的事情

【解决方案1】：

嗯，我知道要在功能应用程序中交换插槽，需要将应用程序设置 WEBSITE_CONTENTSHARE 更改为插槽特定设置。

有关此解决方案和其他有关多插槽的 ARM 问题，请查看 Gary Lumsden 的博客
