Question

当我不使用docker-compose构建我的应用程序时：

docker build -t aspnetapp .
docker run -d -p 8080:80 --name myapp aspnetapp

docker容器运行正常。但是，当我尝试使用docker-compose up运行它时，图像可以成功构建，但是网站在加载时给我错误。

dockerfile：

FROM microsoft/dotnet:sdk AS build-env
WORKDIR /app

RUN curl -sL https://deb.nodesource.com/setup_10.x |  bash -
RUN apt-get install -y nodejs

# 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/dotnet:aspnetcore-runtime
WORKDIR /app
COPY --from=build-env /app/out .
ENTRYPOINT ["dotnet", "app.dll"]

docker-compose：

version: '3.4'

  services:
    app:
      image: aspnetapp     
      build: ./app
      ports:
        - "8080:80"

您的Dockerfile是在0.04183992052616166还是./中？如果在./app中，请将docker-compose.yml更改为./

编辑

我刚刚意识到您在docker-compose.yml中同时指定了build: ./和image；摆脱build。
