docker打包镜像bug记录

项目场景：

Dockerfile：

FROM mcr.microsoft.com/dotnet/core/sdk:3.1-buster AS base
RUN echo "Asia/Shanghai" > /etc/timezone && \
    ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime && \
    sed -i s@/deb.debian.org/@/mirrors.aliyun.com/@/g /etc/apt/sources.list && \
    apt update && \
    apt install -y curl && \
    apt clean && \
    rm -rf /var/lib/apt/lists/*  

HEALTHCHECK --interval=1m --retries=3 --timeout=20s CMD \
    curl -f -s http://127.0.0.1:8080/api/Healthy/Test
WORKDIR /app
EXPOSE 8080

FROM mcr.microsoft.com/dotnet/core/sdk:3.1-buster AS base
WORKDIR /app
RUN ls -l && pwd
COPY BenanUtilities.Jiabao.TestTool.TestServer.sln .
COPY BenanUtilities.Jiabao.TestTool.TestServer.csproj .
RUN dotnet restore
COPY . .
RUN dotnet build

FROM build AS publish
RUN dotnet publish -c Release -o ./publish

FROM base AS final
WORKDIR /app
COPY --from=publish /app/publish .
ENTRYPOINT ["dotnet", "test-server.dll"]

问题1：

docker引擎找不到build，

FROM mcr.microsoft.com/dotnet/core/sdk:3.1-buster AS base   

将build写成了base。

问题2：

 仔细检查，发现

sed -i s@/deb.debian.org/@/mirrors.aliyun.com/@/g /etc/apt/sources.list

 该位置多写了一个斜杠。

问题3：

error MSB1003: Specify a project or solution file. The current working directory does not contain a project or solution file.

 由于在脚本文件里错写了一句“cd publish”, 导致找不到sln或csproj文件，触发此错误。
