Docker 组合端口转发 Linux asp.net 核心

Question

我有几个 docker 图像，它们运行除了端口总是 5000（默认值，在 asp.net 核心），无论我做什么它们没有改变，有什么想法，如何进一步修复或调试？

容器运行宁 Linux (Debian 9) 托管在 Linode

开始构建

docker-compose -f docker-compose.yml向上

Docker-compose.yml

#Api  Service
API:
 build:
  context: .
  #Use the DockerFile in that Directory
  dockerfile: Dockerfile
  #This Service Depends on the database service specifed above
  depends_on:
  - database
#Map port 8888 in the docker container to port 80 in the Api
ports:
  - "5000:80"
restart: always
#Specify Environment Variables for the Api Service
environment:
  - DBHOST=database
  - ASPNETCORE_ENVIRONMENT=Production

Docker文件

FROM mcr.microsoft.com/dotnet/aspnet:5.0 AS base
WORKDIR /app
EXPOSE 80/tcp

FROM mcr.microsoft.com/dotnet/sdk:5.0 AS build

WORKDIR /src
COPY ["TestApi.csproj", "./"]
RUN dotnet restore "TestApi.csproj"
COPY . .
WORKDIR "/src/."
RUN dotnet build "TestApi.csproj" -c Release -o /app/build

FROM build AS publish
RUN dotnet publish "TestApi.csproj" -c Release -o /app/publish


FROM base AS final
WORKDIR /app
COPY --from=publish /app/publish .
ENTRYPOINT ["dotnet", "TestApi.dll"]

docker-compose.debug.yml

version: '3.4'

services:
  testapi:
    image: testapi
    build:
      context: .
      dockerfile: ./Dockerfile
    ports:
      - 80
      - 5000
    environment:
      - ASPNETCORE_ENVIRONMENT=Production
      - ASPNETCORE_URLS=http://+:80
    volumes:
      - ~/.aspnet/https:/https:ro

默认情况下，ASP.NET 核心应用运行在端口 5000（或 5001 用于 TLS）上。您可以通过几种方式更改它，最简单的方法是设置 ASPNETCORE_URLS 环境变量，例如如果你想运行在更典型的 HTTP/S 端口 80/443:

environment:
  - ASPNETCORE_URLS=https://+:443;http://+:80

就是说，我看不出您有任何理由要这样做。为什么不直接绑定到容器上的端口 5000？例如。使用 5000:5000 而不是 5000:80。可能值得阅读文档 here.
