docker与asp.net核心错误dockerfile运行dotnet发布

Question

当我使用docker构建时，我收到这个错误：错误图像

我已经将docker文件上的相对路径更改为绝对路径，将--from=build-env更改为bin/Release/netcoreapp3.1/publish/，但当我使用docker时，错误再次显示

Dockerfile

FROM mcr.microsoft.com/dotnet/core/sdk:3.1 AS build-env
WORKDIR /app
# 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 mcr.microsoft.com/dotnet/core/aspnet:3.1
WORKDIR /app
COPY --from=build-env /app/out .
ENTRYPOINT ["dotnet", "SmartSchool.WebAPI.dll"]

我添加了使用vscode命令ctrl + shift + p和docker: add docker files to workspace 创建的dockerigno

我用过这个。dockerignore在下面

**/.classpath
**/.dockerignore
**/.env
**/.git
**/.gitignore
**/.project
**/.settings
**/.toolstarget
**/.vs
**/.vscode
**/*.*proj.user
**/*.dbmdl
**/*.jfm
**/azds.yaml
**/bin
**/charts
**/docker-compose*
**/Dockerfile*
**/node_modules
**/npm-debug.log
**/obj
**/secrets.dev.yaml
**/values.dev.yaml
