Dockerfile compatibility with Raspberry Pi?

7/1/2019

I have built the image from the following Dockerfile in my Rpi Kubernetes cluster. However, I was getting status of CrashLoopBackOff for my Pods.

After a bit of search on the internet, I realized that the problem maybe is with the Dockerfile's compatibility with RPi. I get following error when I run docker logs CONTAINER_ID

standard_init_linux.go:190: exec user process caused "exec format error"

The 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"]

Moreover, I get the following error on Rpi if I build the same image on Pi:

EDIT: the problem seems to be at git and also at apt-get install git or because running both separately give me the following error:

Solved the problem with a few changes in the Dockerfile. The problem was with spacing I think and I had to put RUN for some commands plus -y tag helped at some places for the reasons I don't know. Would like if someone could explain more.
