arm & arm 64 build doesn't work

[bastilimbach]

I think you can't use FROM node:12-stretch in your Dockerfile for different architectures. With this line, it will pull the x86_64 image because the travis-runner has this architecture. So you have to use different images for every architecture, e.g. arm32v7/node:12-stretch for arm (with qemu).

Was researching this as I'm also having the same issue (docker on raspberry pi 3) and came across a thread that mentioned it could be showing this error due to the windows style line (CRLF) endings on the entrypoint script. Any chance that's causing the issue here?

See https://nickjanetakis.com/blog/fixing-exec-format-errors-with-docker-entrypoint-scripts-on-windows

[bastilimbach]

Mhh, maybe. We previously had some steps in the Dockerfile to transform the line endings but I removed it as I thought this was not necessary anymore. I’ll create a separate branch and test it. @jtuckr would you be able to test it as soon as I push a new version? I currently do not have a raspberry pi at hand.

[jtuckr]

Yes definitely.

[khassel]

Any chance that's causing the issue here?

no:

pi@raspberrypi:~ $ docker run --rm -it --entrypoint /bin/sh bastilimbach/docker-magicmirror:latest
standard_init_linux.go:211: exec user process caused "exec format error"

docker-entrypoint.sh is not involved here ...

[KamilLenica]

any news on this issue? I can test it right away on my RPi4

I've rebuilt the Dockerfile and it works! I've used FROM arm32v7/node:12-stretch and build image using docker build -t "arm-mmirror" .

[jtuckr]

That appears to have worked for me as well, but now having issues actually pulling up magic mirror where it is listening.

To summarize, here's what I did that got me this far:

1. git cloned the repo git clone https://github.com/bastilimbach/docker-MagicMirror.git
2. cd into the directory cd docker-MagicMirror
3. modified the Dockerfile using a text editor so the top line said FROM arm32v7/node:12-stretch and saved the file
4. Ran docker build -t arm-mmirror command (I had to run it as sudo, but otherwise it worked fine after some time)
5. Ran a version of the docker run command from the README, but in mine I referenced the arm-mmirror image I just built instead of bastilimbach/docker-magicmirror. Complete command I ran: docker run -d \ --publish 80:8181 \ --restart always \ --volume ~/magic_mirror/config:/opt/magic_mirror/config \ --volume ~/magic_mirror/modules:/opt/magic_mirror/modules \ --name magic_mirror \ arm-mmirror (note: I have a copy of the "sample" config.js located under ~/magic_mirror/config but I modified the port line to 8181 from its default of 8080)
6. then I inspected the logs by running docker logs magic_mirror and this is what I see in the output:

[05:26:18.582] [LOG] Starting MagicMirror: v2.10.0 [05:26:18.618] [LOG] Loading config ... [05:26:18.645] [LOG] Loading module helpers ... [05:26:18.653] [LOG] No helper found for module: alert.

[05:26:21.084] [LOG] Ready to go! Please point your browser to: http://localhost:8181

6. Open my browser and navigate to http://localhost:8181 and... "localhost refused to connect".

So i'm a bit at a loss on that last bit. Is there a firewall setting or something that I need to change? Before, running magic mirror on this same pi using pm2 would work fine, but it wasn't using serveronly mode I understand, so this is a little different. Any help or guidance would be appreciated!

"localhost refused to connect". I'm having the same issue, commenting here to check later for any solutions

[mkilinskidev]

According to localhost refused to conection I think there is an error in documentation. Use address: "0.0.0.0" in your config.js file. Did you changed in Docerfile EXPOSE line? If you are modyfing a docker port, I think you should change this line too. Here is my complete Dockerfile:

FROM arm32v7/node:12-stretch

RUN apt-get update

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 mm-docker-config.js docker-entrypoint.sh ./
RUN chmod +x ./docker-entrypoint.sh

EXPOSE 8889
ENTRYPOINT ["./docker-entrypoint.sh"]
CMD ["node", "serveronly"]

And then config.js file:

var config = {
  address: "0.0.0.0", // Address to listen on, can be:
  // - "localhost", "127.0.0.1", "::1" to listen on loopback interface
  // - another specific IPv4/6 to listen on a specific interface
  // - "", "0.0.0.0", "::" to listen on any interface
  // Default, when address config is left out, is "localhost"
  port: 8889,
  ipWhitelist: [], // Set [] to allow all IP addresses
  // or add a specific IPv4 of 192.168.1.5 :
  // ["127.0.0.1", "::ffff:127.0.0.1", "::1", "::ffff:192.168.1.5"],
  // or IPv4 range of 192.168.3.0 --> 192.168.3.15 use CIDR format :
  // ["127.0.0.1", "::ffff:127.0.0.1", "::1", "::ffff:192.168.3.0/28"],

   `docker run  -d \ --publish 80:8181 \  ...
1. Open my browser and navigate to http://localhost:8181 and...
   "localhost refused to connect".

The port outside on the host ist 80, so you have to navigate to http://localhost:80

[theiam79]

FWIW, I'm using Unraid as my host and it didn't work until I set both the host and container port to the same port number and configured that port in the config.js

[jtuckr]

@c0degeekPL I tried changing the config.js as you suggested but no luck. I think I'll need to try changing the EXPOSE line you suggested also and rebuild the image and container.

I tested accessing localhost:80 as well as localhost:8080 and 8181 and all had the same response. Will do some more tweaking and give it another shot later. Thanks all!

[jtuckr]

@c0degeekPL the EXPOSE line change worked! I used the port you gave in your dockerfile and config.js file just to try something unique to my configuration. That, with docker run -d \ --publish 8889:8889 in my docker run command fixed my issues.

Thanks everyone for all your help!

@KamilLenica Could you test the latest build? See #33

Not right now, I am away on bussiness trip without access to my Raspberry.

Will do as soon as possible, but no sooner than 18th of February

[bastilimbach]

I tested it on my raspberry pi. Works as expected 👍 Again thanks @khassel!
