运行netcore react应用程序时出现docker compose错误

当我不使用docker compose构建应用程序时:

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

docker容器运行正常。但当我尝试运行它时,使用 docker-compose up ,图像生成成功,但网站在加载时给了我错误。

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"
