docker - docker-compose无法连接到asp.net核心站点

Question

我正在尝试根据Windows Server 2016上的https://docs.docker.com/get-started/part3为ASP.NET Core应用程序运行docker-compose。

Docker文件

FROM microsoft/aspnetcore-build:2.0 AS build-env
WORKDIR /app
EXPOSE 80

# Copy csproj and restore as distinct layers
COPY *.csproj ./
RUN dotnet restore

# Copy everything else and build
COPY . ./
RUN dotnet publish -c Release -o out

# Build runtime image
FROM microsoft/aspnetcore:2.0
WORKDIR /app
COPY --from=build-env /app/out .
ENTRYPOINT ["dotnet", "Community.dll"]

docker-compose.yml

version: "3"
services:
  web:
    image: linuxchata/community-app:v1
    deploy:
      replicas: 1
      resources:
        limits:
          memory: 500M
      restart_policy:
        condition: on-failure
    ports:
      - "80:4000"
    networks:
      - webnet
networks:
  webnet:

通过运行以下命令已创建服务

docker stack deploy -c docker-compose.yml community

docker service ls命令

ID                  NAME                MODE                REPLICAS            IMAGE                         PORTS
t5jsy98xkl5p        community_web       replicated          1/1                 linuxchata/community-app:v1   *:80->4000/tcp

http://127.0.0.1:4000/， http://localhost:4000/和 http://servername:4000/无法通过浏览器使用。但是，运行单个容器按预期运行(通过docker run命令)。

您能告诉我这里可能是个问题吗？更多细节如下。

正确的Docker撰写文件

version: "3.5"

services:
  web:
    image: linuxchata/community-app:v1
    restart: on-failure
    ports:
      - "4000:80"
    networks:
      - webnet
networks:
  webnet:

运行docker compose docker-compose -f docker-compose.yml up -d的命令
