Dockerfile:COPY static Swagger没有这样的文件或目录错误

Question

Docker找不到我的静态Swagger文件。我的代码在localhost上运行，但当我尝试在临时服务器上运行时，我在AWS CodePipeline中遇到以下错误：

COPY failed: stat /var/lib/docker/overlay2/ebbaca51ed1994dce1148a3fdcdbb80dafa1f3266bad100393bbd2d27413b607/merged/app/TimeProject.Beta.Nswag/specification: no such file or directory` 

我的docker文件：

FROM mcr.microsoft.com/dotnet/core/sdk:3.1 AS build
ARG asmver=1.0.0.0
WORKDIR /source
COPY . .
RUN dotnet restore --configfile Application.Startup/NuGet.Config Application.Startup/Application.Startup.csproj
RUN dotnet publish -c Release -o /app Application.Startup/Application.Startup.csproj /p:AssemblyVersion=$asmver
COPY Application.Startup/cert.pfx /app/cert.pfx
FROM mcr.microsoft.com/dotnet/core/aspnet:3.1 AS runtime
WORKDIR /app
# https://github.com/dotnet/runtime/issues/30667 -> To be fixed in .Net 5.0
RUN sed -i "s|DEFAULT@SECLEVEL=2|DEFAULT@SECLEVEL=1|g" /etc/ssl/openssl.cnf
RUN mkdir ../TimeProject.Beta.Nswag
RUN mkdir ../TimeProject.Beta.Nswag/specification
COPY --from=build /app .
COPY --from=build /app ./
RUN pwd
RUN dir
COPY --from=build /app/TimeProject.Beta.Nswag/specification/ ../TimeProject.Beta.Nswag/specification
ENTRYPOINT ["dotnet", "Application.Startup.dll"]

CodeBuild-Docker.yaml:

version: 0.2
phases:
install:
runtime-versions:
docker: latest
dotnet: 3.1
pre_build:
commands:
- $(aws ecr get-login --no-include-email --region $AWS_DEFAULT_REGION)
build:
commands:
- echo $RELEASE_VERSION
- cd src/app
- docker build . -f Application.Startup/Dockerfile -t $IMAGE_REPO_NAME:$RELEASE_VERSION --build-arg asmver=$RELEASE_VERSION
- docker tag $IMAGE_REPO_NAME:$RELEASE_VERSION $AWS_ACCOUNT_ID.dkr.ecr.$AWS_DEFAULT_REGION.amazonaws.com/$IMAGE_REPO_NAME:$RELEASE_VERSION
post_build:
commands:
- docker push $AWS_ACCOUNT_ID.dkr.ecr.$AWS_DEFAULT_REGION.amazonaws.com/$IMAGE_REPO_NAME:$RELEASE_VERSION

通过删除解决

COPY Application.Startup/cert.pfx /app/cert.pfx

和

COPY --from=build /app .

，并通过添加

EXPOSE 5001
