这是我的Dockerfile

FROM microsoft/aspnetcore-build as build-stage
ARG source=.
WORKDIR /app
COPY $source/sample-api.csproj .
RUN dotnet restore
COPY $source .
RUN dotnet publish -o /publish

FROM microsoft/aspnetcore
WORKDIR /sample-api
COPY --from=build-stage /publish .
EXPOSE 3000
ENTRYPOINT dotnet sample-api.dll

这将创建2张图片

REPOSITORY     TAG          IMAGE ID
sample-api     latest       
<none>         <none>

是否可以<none>从第二阶段删除第一阶段图像？执行第二阶段的COPY后不再需要COPY --from=build-stage /publish .
