docker - Dockerfile是否与Raspberry Pi兼容？

Question

我已经从Rpi Kubernetes集群中的以下Dockerfile中构建了镜像。但是，我的Pod的状态为CrashLoopBackOff。

在互联网上进行了一些搜索之后，我意识到问题可能出在Dockerfile与RPi的兼容性。
运行docker logs CONTAINER_ID时出现以下错误
standard_init_linux.go:190: exec user process caused "exec format error"
Dockerfile:

FROM ubuntu:18.04

RUN apt-get update && apt-get install -y \
    git \
    software-properties-common \ 
    python3-pip git
RUN add-apt-repository universe \
    && apt-get update
RUN pip3 install tornado sqlalchemy construct==2.5.5-reupload
RUN git clone https://github.com/majadoon/empower-runtime.git
RUN cd empower-runtime \
    && mkdir deploy

EXPOSE 8000 4433

WORKDIR /empower-runtime

CMD ["./empower-runtime.py"]

此外，如果我在Pi上构建相同的镜像，则会在Rpi上收到以下错误:

编辑:问题似乎是在git和apt-get install git上，或者因为分别运行两个给我以下错误:

通过在Dockerfile中进行一些更改解决了该问题。我认为问题在于间距，我不得不将RUN用于某些命令，加上-y标签在某些地方有所帮助，原因是我不知道。想知道是否有人可以解释更多。
