无法构建 docker 容器：无法将文件 <file> 添加到 tar: io: read/write on closed pipe
Unable to build docker container: Can't add file <file> to tar: io: read/write on closed pipe
我正在尝试通过 ssh 从 mac 在 raspberry pi 上构建容器。我将 DOCKER_HOST 设置为 ssh://root@192.168.1.11（192.168.1.11 是我 raspberry pi 的 IP）。
docker 构建命令失败并显示以下错误消息：
ERRO[0000] Can't add file /Users/brian/git/github/proj/backend/apps/accounts/managers.py to tar: io: read/write on closed pipe
ERRO[0000] Can't close tar writer: io: read/write on closed pipe

我 mac 上的 docker 版本是：
docker --version
Docker version 20.10.7, build f0df350
我的 raspberry pi 上的 docker 版本是：
docker --version
Docker version 20.10.7, build 20.10.7-0ubuntu1~20.04.1
我正在尝试构建的容器使用此 Docker 文件：
FROM --platform=linux/amd64 python:3.9
ENV PYTHONUNBUFFERED 1
ENV PYTHONDONTWRITEBYTECODE 1
RUN mkdir /code
WORKDIR /code
ADD requirements.txt /code/
RUN pip3 install -r requirements.txt
ADD . /code/
RUN useradd -m app
USER app
我可以在我的 mac 和 raspberry pi.
上使用这个 Docker 文件构建图像
我在 SO/GitHub 上发现了其他一些可能相关的问题：
- Docker "Can't add file <path> to tar: readlink <path> The system cannot find the file specified"
以下是来自 raspberry pi 的更多信息：
ubuntu@ubuntu:~$ df -h

关于 raspberry pi 我无法从失败的构建命令中查找日志。如果我在 raspberry pi 上重新启动 docker：
sudo systemctl restart docker
然后获取日志：
sudo journalctl -fu docker.service
然后 运行 再次执行 docker 构建命令，当我再次 运行 sudo journalctl -fu docker.service 时我没有看到任何新日志。
还有其他方法可以调试失败的 docker 构建命令吗？

我已经解决了最初的问题，但我现在面临着关于平台兼容性的评论中提出的一个单独的问题。我不得不在基本图像中从 Python 3.9 切换到 Python 3.8，并且还在基本图像中指定了 --platform="linux/arm64"：
