raspberry pi - install & use magicmirror under docker

[lpt2007]

I used raspbian-desktop from this link:
https://www.raspberrypi.org/downloads/raspbian/

I enabled ssh with:

sudo systemctl enable ssh

I update host system:

sudo apt-get -y update
sudo apt-get -y upgrade

run raspi-config:
sudo raspi-config

go to -> "Interfacing Options" -> "Camera" -> Enable,
go to -> "Advanced Options" -> "Memory Split" -> 256
go to -> "Finish" -> "Reboot"

I installed docker:

curl -fsSL get.docker.com -o get-docker.sh && sh get-docker.sh
sudo usermod -aG docker pi

I Installed x11docker:

wget https://raw.githubusercontent.com/mviereck/x11docker/master/x11docker -O /tmp/x11docker
sudo bash /tmp/x11docker --update
rm /tmp/x11docker

I create folders:

mkdir /home/pi/docker
mkdir /home/pi/docker/magicmirror

create and edit Dockerfile:
nano /home/pi/docker/magicmirror/Dockerfile

add this:

FROM hypriot/rpi-node:latest

ENV NODE_ENV production

WORKDIR /opt/magic_mirror

RUN git clone --depth 1 -b master https://github.com/MichMich/MagicMirror.git .

RUN cp -R modules /opt/default_modules
RUN cp -R config /opt/default_config
RUN npm install --unsafe-perm --silent

COPY docker-entrypoint.sh /opt
RUN apt-get update \
  && apt-get -qy install dos2unix \
  && dos2unix /opt/docker-entrypoint.sh \
  && chmod +x /opt/docker-entrypoint.sh

RUN apt-get -y install libgtk-3-0
RUN apt-get -y install libx11-xcb-dev
RUN apt-get -y install libxtst6
RUN apt-get -y install libxss1
RUN apt-get -y install libgconf-2-4
RUN apt-get -y install libnss3
RUN apt-get -y install libasound2

EXPOSE 8080
CMD ["npm start"]
ENTRYPOINT ["/opt/docker-entrypoint.sh"]

create and edit Dockerfile:
nano /home/pi/docker/magicmirror/docker-entrypoint.sh

add this:

#!/bin/bash

if [ ! -f /opt/magic_mirror/modules ]; then
    cp -Rn /opt/default_modules/. /opt/magic_mirror/modules
fi

if [ ! -f /opt/magic_mirror/config ]; then
    cp -Rn /opt/default_config/. /opt/magic_mirror/config
fi

$@

build docker container:
sudo docker build -t magicmirror /home/pi/docker/magicmirror

from ssh I run this:

sudo x11docker --user=root --xorg magicmirror
