Error starting up on raspberry pi

[theTisch21]

Hi, I am trying to set up mildred on my raspberry pi. Running docker-compose up in the directory of mildred results in Starting mildred ... done Attaching to mildred mildred | standard_init_linux.go:211: exec user process caused "exec format error" mildred exited with code 1

I'm not sure what to do here, I've set permissions on the mildred directory to 777 and tried running the docker command with sudo, and running it as root. Is there something I'm doing wrong? Or is mildred not compatible with ARM processers?

Thanks! -Sam

Hi Sam,

The dongyg/mildred image is based-on https://hub.docker.com/_/python

FROM python:3.8-slim-buster
...

Try to build yourselves image like below

FROM amd64/python:3.8-slim-buster

RUN pip install --no-cache-dir web.py==0.51 pyyaml==5.3.1 rsa==4.0 image==1.5.32 qrcode==6.1 docker==4.2.0 docker-compose==1.26.0;
ENV RUNNING_INSIDE_CONTAINER 1
# COPY code /mildred/code/
WORKDIR /mildred/code

Sorry for the very late response! My rapsberry pi broke, and it took me a while to get it working with docker again. I tested your dockerfile, and it gave me a dependency error. Here is my log, starting a minute or two before the error:

To fix this you could try to:
1. loosen the range of package versions you've specified
2. remove package versions to allow pip attempt to solve the dependency conflict

[dongyg]

It seems like pip was looking for a right version docker package for the docker server you have on your raspberry pi.

My suggestion is flow the log and remove the specific version for docker and docker-compose, like this:

FROM amd64/python:3.8-slim-buster

RUN pip install --no-cache-dir web.py==0.51 pyyaml==5.3.1 rsa==4.0 image==1.5.32 qrcode==6.1 docker docker-compose;
ENV RUNNING_INSIDE_CONTAINER 1
WORKDIR /mildred/code

[theTisch21]

One thing I forgot to mention, the amd64/ in the image tag cased another error. I switched to prefixing it with arm32v7 to make it work on my raspberry pi. When I tried to build the file in your most recent comment with the python image FROM arm32v7/python:3.8-slim-buster, It gets stuck trying to find compatible versions of all the dependencies for docker-compose. Are the dependencies only compatible with amd64 images?

[dongyg]

I am not sure if the docker-compose is compatible with arm32/64 platform. It is not mentioned on https://pypi.org/project/docker-compose.

Maybe you can try to remove the docker-compose dependency. The features about docker won't be impacted.

I can try to do some tests next week on an Apple M1 computer. I will tell you if I have any news.

Another option, you can wait for a while for the next release of the Mildred App. The new version will support the SSH connection. The docker-compose feature will not need the docker-compose package for python.

[agneevX]

Can you add support for Portainer connection?

[theTisch21]

@dongyg leaving out the docker-compose dependency causes there to be an error when building the pillow package for some reason. I've decided to wait for the next release of the app and use an SSH connection. If you'd like to, you may close this issue, or leave it open. Thanks for all the help!

[dongyg]

@theTisch21 I remove the package pillow. I also rebuild the docker image. Now the image supports amd64, arm64, armv7. https://hub.docker.com/r/dongyg/mildred/tags. The new version App will be launched soon with SSH support.

[theTisch21]

It appears to be working great with the new image! Thanks for all the help.
