docker 构建卡在 dotnet 恢复上

Question

我正在尝试创建 .NET 6 项目的 docker 图像，但在使用 +12GB RAM 时卡在 dotnet restore 期间。

我的项目结构是：

- backend/
- frontend/

我只是 cd 在 backend/ 和运行 docker build .

这是当前控制台的输出：

这是我的 Dockerfile：

# syntax=docker/dockerfile:1
FROM mcr.microsoft.com/dotnet/sdk:6.0 AS build-env
WORKDIR /app

ARG Config=Debug
ENV ASPNETCORE_URLS=http://*:5000

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

# Copy everything
COPY . .

# Publish
RUN dotnet publish -c ${Config} -o /app/publish

# Build runtime image
FROM mcr.microsoft.com/dotnet/aspnet:6.0
WORKDIR /app
COPY --from=build-env /app/publish .
ENTRYPOINT ["dotnet", "myapp.dll"]

已解决，问题出在我的.csproj

 <ItemGroup>
    <Watch Include="..\**\*.env" />
  </ItemGroup>

我改成了：

  <ItemGroup>
    <Watch Include="..\**\*.env" Condition="'$(DOTNET_RUNNING_IN_CONTAINER)' != 'true'" />
  </ItemGroup>
