dotnet core app api不会继续在kubernetes上运行

Question

我正在将一个dotnet核心应用程序设置为kubernetes集群,我收到错误"无法启动红隼".

Dockerfile在本地计算机上运行正常.

Unable to start Kestrel.

我的dockerfile:

[...build step]
FROM microsoft/dotnet:2.1-aspnetcore-runtime
COPY --from=build-env /app/out ./app
ENV PORT=5000
ENV ASPNETCORE_URLS=http://+:${PORT}
WORKDIR /app
EXPOSE $PORT
ENTRYPOINT [ "dotnet", "Gateway.dll" ]

我期望应用程序成功启动,但我收到此错误"无法启动红隼".

[ 更新 ]

我从应用程序中删除了https端口并在没有https的情况下再次尝试,但现在应用程序只是启动和停止而没有任何错误或警告.容器日志波纹管:

使用dotnet运行本地运行或构建映像并从容器运行,一切正常.应用程序刚关闭到kubernetes.

我使用的是dotnet core 2.2

[ 更新 ]

我已经生成了一个证书,在项目中添加,在kestrel中设置,我得到了相同的结果.Localhost使用docker imagem它工作,但在kubernetes(谷歌云),它只是在它启动后立即关闭.

本地主机:

$ docker run --rm -it -p 5000:5000/tcp -p 5001:5001/tcp juooo:latest

Answer 1

我发现一个事件日志，其中包含 kubernetes 错误，指出 kubernetes 无法命中 (:5000/)。所以我尝试创建一个针对根应用程序的控制器（因为它是一个 api，所以没有像网络应用程序那样的根）并且它起作用了。
