尝试在 ARM64 Apple M1 中构建时出现 Docker 错误：“无法解析当前可执行文件的完整路径 [/proc/self/exe]”

Question

我在 Apple M1 上构建 docker 容器时遇到问题 该项目使用与 arm64 架构不兼容的 sdk 2.2。因此，我将 sdk 和 aspnet 核心更改为 2.2-alpine3.8，它们似乎构建正常，但在需要发布时进程失败

docker 文件：

FROM mcr.microsoft.com/dotnet/core/sdk:2.2-alpine3.8 AS build-env
WORKDIR /app
# Copy csproj and restore as distinct layers
COPY . .
RUN dotnet publish src/admin/MyContainer.Admin.csproj -c Release -o ./publish

# Build runtime image
FROM mcr.microsoft.com/dotnet/core/aspnet:2.2-alpine3.8
WORKDIR /app
COPY --from=build-env /app/src/admin/publish .

# Copy script that allows waiting for the database on docker-compose
# As referenced here https://docs.docker.com/compose/startup-order/
# This was done because admin starts up very quickly on e2e env
# and the sqlserver container wasn't getting ready fast enough
COPY --from=build-env /app/docker-wait-for-it.sh .

EXPOSE 80
CMD ["dotnet", "MyContainer.Admin.dll"]

我使用的构建命令是：

docker buildx build --platform linux/arm64/v8 -t MyContainer.azurecr.io/admin-api-web:development ./backend -f ./backend/Admin.Api.Web.Dockerfile

日志输出为：

我发现这是因为核心 2.2 不支持 arm64。但是这个文件在英特尔 MacBook 上构建没有任何错误，但使用 M1 我无法克服构建错误。有什么想法吗？

Answer 1

这不是一个答案，而是对问题的跟进， 这可能会更清楚地说明这个问题。

我正在使用 aspnet:6，它通过了构建。

后面的问题是可运行的 .dll 抛出

cannot execute binary file: Exec format error

这似乎是一个平台问题，使用带有 M1 Silicon 芯片组的 Mac。

我对为 linux/amd64 制作的其他 docker 映像没有任何问题

Docker 守护进程似乎可以很好地处理这个问题（已安装 Rosetta2 和 M1 的最新 Docker 桌面） https://docs.docker.com/desktop/mac/apple-silicon/

您是否设法解决了问题并执行了 dll？
