问题描述
当我创建后端池并将其设置为以App Service为目标时，下拉列表仅显示应用服务"myAppService"。但没有列出任何其他插槽"myAppService-dev"和"myappService-staging"。
When I create a Backend Pool and set it to target an App Service, the drop down list only shows the app service "myAppService" but does not list any of the other slots "myAppService-dev" and "myappService-staging".
我之前设置了一个应用程序网关，它在我设置后端池时向我显示了所有插槽的名称。从那时起，我已经删除了App Gateway，以防它在我想要连接新App Gateway的插槽上保留。
I had previously set up an Application Gateway that had revealed to me the names of all the slots when I set up a backend Pool. Since then, I have deleted that App Gateway in case it had a hold on the slot I want to connect the new App Gateway to.
我运行App Gateway的连接故障排除>来源dev-myAG>目的地>
手动指定> myappservice-dev.azurewebsites.net，端口80 >
检查：状态返回OK已通过100/100探测。 ;我不知道为什么后端池不会向我提供开发和暂存槽。
I ran the App Gateway's Connection troubleshoot > Source dev-myAG > Destination >
specify manually > myappservice-dev.azurewebsites.net, port 80 >
Check: Status returns OK 100/100 probes passed. I am at a loss as to why the backend pool will not offer the dev and staging slots to me.
推荐答案
据我所知，应用程序网关不支持部署插槽作为后端池。
as far as I know, the application gateway does not support deployment slots as backend pool.
also there is a vote about this: https://feedback.azure.com/forums/34192--general-feedback/suggestions/35365912-application-gateway-web-app-slot-support-as-backen
我刚检查了我的应用程序网关，它只列出了邮件部署，而不是部署插槽。
I just checked my Application Gateway and it lists only the mail deployment, not the deployment slots.
但是既然您看到了以前的应用程序网关，那么就列出了部署插槽，您可以打开票证并让我们知道答案
but since you saw your previous application gateway it was listed the deployment slots you can open a ticket and let us know the answer
