Docker-compose 无法访问 .NET Core [英] Docker-compose with .NET Core unreachable

问题描述

我是 Docker 的新手，我正在尝试设置 2 个容器，一个运行 mongoDB，一个运行 Web 应用程序.

问题是我无法通过 localhost:5000 或 0.0.0.0:5000 访问我的 .NET 核心应用程序.

Mongo 运行良好.

这是我的 docker-compose.yml

版本:'3'服务:网络:建造: .端口:- 5000:5000"蒙戈:构建:../../../docker/wishare-mongo/卷:- ../../../docker/wishare-mongo:/data/db端口:- 27017:27017"

用于 .NET Core 应用程序的 Dockerfile

FROM microsoft/aspnetcore-build:2.0 AS build-env工作目录/应用程序ENV ASPNETCORE_URLS="http://*:5000"# 复制 csproj 并恢复为不同的层复制 *.csproj ./运行 dotnet 还原# 复制其他所有内容并构建复制 ../运行 dotnet publish -c Release -o out# 构建运行时镜像从微软/aspnetcore:2.0工作目录/应用程序复制 --from=build-env/app/out .曝光 5000入口点 ["dotnet", "Wishare-Integration-Api.dll"]

docker-compose build 和 docker-compose up 运行没有错误，这导致了 web 容器:

<块引用>

web_1 |托管环境:生产web_1 |内容根路径:/app web_1 |现在听:

有什么想法吗?

解决方案

看起来 .NET 在生产中使用端口 80，所以当我更改 docker 文件并导出端口 80 而不是 5000 并且也在 docker 中将端口 5000 更改为端口 80 时-撰写它按预期工作.

所以我假设为了在端口 5000 上运行它，它需要在 .NET 端进行一些配置.

Im new to Docker and im trying to set up 2 containers, one running mongoDB and one running the web application.

The problem is that I can not access my .NET core application via localhost:5000 or 0.0.0.0:5000.

Mongo is running fine.

Here is my docker-compose.yml

version: '3'
services:
  web:
    build: .
    ports:
     - "5000:5000"
  mongo:
    build: ../../../docker/wishare-mongo/
    volumes:
     - ../../../docker/wishare-mongo:/data/db
    ports:
     - "27017:27017"

Dockerfile for .NET Core app

FROM microsoft/aspnetcore-build:2.0 AS build-env
WORKDIR /app
ENV ASPNETCORE_URLS="http://*:5000"

# 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 .
EXPOSE 5000
ENTRYPOINT ["dotnet", "Wishare-Integration-Api.dll"]

The docker-compose build and docker-compose up runs without an error with this resulting for web container:

web_1 | Hosting environment: Production web_1 | Content root path: /app web_1 | Now listening on: http://[::]:80 web_1 | Application started. Press Ctrl+C to shut down.

And this is the result of docker ps, port 5000 should be exported based on docker ps result.

Any ideas?

解决方案

Looks like .NET uses port 80 in production, so when Ive changed docker file and exported port 80 instead of 5000 and also changed port 5000 to port 80 in docker-compose it works as supposed.

So I assume in order to run it on port 5000 it will need some configuration on .NET side.
