docker - Azure Web App + Docker + Linux：必须指定服务器错误 Host.DestinationHostUrl

Question

在 Azure Web App docker 容器日志中看到以下错误：

2019-09-10T22:09:56.042029809Z Unhandled Exception: System.InvalidOperationException: Host.DestinationHostUrl must be specified either as an environment variable or as a command-line switch.

请注意，这是在 linux docker 映像上运行的。不确定这是内部问题还是我的 docker 映像有问题。Dockerfile 非常简单：

FROM node:lts

# Copying source files
ARG BUILDDIR=.
ADD $BUILDDIR/foo .

# Installing dependencies
RUN npm install

# Building app
RUN npm run build

# Running the app
CMD [ "npm", "start" ]

感谢有关如何解决此问题的任何指示。
