Docker 容器 - Visual Studio 2022 调试版本中 https 端口没有响应

Question

我正在尝试将 aspnet 核心应用程序移动到 docker。不幸的是我无法让应用程序在端口 https 8081 上运行。我尝试了几件事（请参阅下面的配置），但是当尝试在浏览器中通过 https 打开应用程序时，没有任何反应（我什至在容器日志文件中没有看到错误）。

我设法让应用程序在端口 8080 的 http 上运行，但不能在 https 上运行

这是我到目前为止的配置：

Dockerfile：

我安装了额外的软件包，例如curl，以便能够获取有关正在运行的进程和端口8081上的内部http请求的更多详细信息。

#how to use the asp.net image as base

FROM mcr.microsoft.com/dotnet/aspnet:8.0 AS base
USER app
WORKDIR /app
EXPOSE 8081


FROM mcr.microsoft.com/dotnet/aspnet:8.0 AS base
#Install the .NET Core runtime
COPY --from=mcr.microsoft.com/dotnet/sdk:8.0 /usr/share/dotnet/sdk /usr/share/dotnet/sdk
# Instlling the required packages
RUN apt-get update && apt-get install -y procps telnet curl iproute2 wget

证书是使用 docker 镜像的 bash 通过 openssl 制作的，并添加到 kestrel 配置中。

红隼配置：

"Kestrel": {
  "Endpoints": {
    "Https": {
      "Url": "https://localhost:8081",
      "Certificate": {
        "Path": "/cert/localhost.crt",
        "KeyPath": "/cert/localhost.key"
      }
    }
  }
}

VisualStudio 2022 版本 17.11.0 中的我的启动设置：

 "SDir Docker": {
   "commandName": "Docker",
   "launchBrowser": false,
   "launchUrl": "{Scheme}://{ServiceHost}:{ServicePort}",
   "DockerfileRunArguments": "-p 5001:8081 -p 5000:8080 -v C:\\Users\\dumit\\.aspnet\\https\\:/cert:ro -v D:\\guis\\myservice2dev\\:/frontend:rw -v C:\\temp\\myservice\\database\\:/database:rw -v C:\\temp\\myservice\\plugins\\:/plugins:rw -v C:\\temp\\myservice\\logs\\:/logs:rw -v C:\\temp\\myservice\\secret\\:/secret:rw",
   "environmentVariables": {
     "ASPNETCORE_ENVIRONMENT": "Development",
     "ASPNETCORE_URLS": "https://+:8081;http://+:8080",
     "ASPNETCORE_HTTPS_PORT": "8081",
     "ASPNETCORE_HTTP_PORT": "8080"
   }
 },

在 VS 2022 调试模式下启动容器时，docker-compose 似乎没有效果，因为它使用某种快速模式，其中很多事情都会在后台自动完成。

docker-compose.yml：

services:
  myservice:
    build:
      context: ../../../
      dockerfile: MyServices/Backend/MyService/Dockerfile
      args:
        nuget_pat: ${AZURE_AUTH_TOKEN}
    ports:
      - "5001:8081"
      - "5000:8080"
    environment:
      ASPNETCORE_ENVIRONMENT: Development
      ASPNETCORE_HTTPS_PORT: "8081"
      ASPNETCORE_HTTP_PORT: "8080"
      ASPNETCORE_URLS: "https://+:8081;http://+:8080"
      ASPNETCORE_Kestrel__Certificates__Default__Path: "/cert/localhost.crt"
      ASPNETCORE_Kestrel__Certificates__Default__Password: "SomeFancyPassword"
    volumes:
      - ${APPDATA}\microsoft\UserSecrets\:/root/.microsoft/usersecrets
      - ${USERPROFILE}\.aspnet\\https\\:/https:ro
      - D:\\guis\\myService2dev\\:/frontend:rw
      - C:\\temp\\myService\\database\\:/database:rw
      - C:\\temp\\myService\\plugins\\:/plugins:rw
      - C:\\temp\\myService\\logs\\:/logs:rw"

容器启动时，端口配置为映射 5001 -> 8081：

构建 Docker 镜像后，我还执行了以下步骤：

# Copy SSL certificates to the container
copied the localhost.crt to /usr/local/share/ca-certificates/

# Update SSL certificates in the container bash

update-ca-certificates

启用证书后，我终于通过使用curl得到了回复：

root@9d7ee1765902:/# curl https://localhost:8081
<!doctype html>
<html lang="en" data-n-head="%7B%22lang%22:%7B%221%22:%22en%22%7D%7D">
  <head>
    ...some more html here...
  <script src="/52c0694.js"></script><script src="/77b5243.js"></script></body>
</html>
root@9d7ee1765902:/#

我已经在调试模式下启用了日志，并在curl请求后获得此输出：

有人对如何解决此问题有更多想法吗？

看来我的 Kestrel 部分不正确。我最终没有在网址中使用 https://localhost:8081 而是使用

"Kestrel": {
  "Endpoints": {
    "Https": {
      "Url": "https://+:8081"
    }
  },
  "Certificates": {
    "Default": {
      "Path": "/cert/localhost.crt",
      "KeyPath": "/cert/localhost.key"
    }
  }
}

现在在日志中我收到此消息：

info: Microsoft.Hosting.Lifetime[14]
      Now listening on: https://[::]:8081
