Installing Mealie on Raspberry Pi

[palaplan]

I am trying to run a Docker image of Mealie on my Raspberry Pi 4 Model B. I copied Raspberry Pi OS on a Micro SD card using the Raspberry Pi Imager (the default version is the 32 bits OS). I then installed Docker following these instructions but was not able to run

docker run \
    -p 9925:80 \
    -v `pwd`:'/app/data/' \
    hkotel/mealie:latest

the error I got was

docker: no matching manifest for linux/arm/v7 in the manifest list entries. 

I then found the Docker image of the version 0.4.3 that support linux/arm/v7 and was able to run it running the following:

docker run \
    -p 9925:80 \
    -v `pwd`:'/app/data/' \
    hkotel/mealie:v0.4.3

So it runs nicely now but the version is now almost 2 years old.

I am assuming that the Docker images now only support 64 bit systems and that I will need to install the 64 bits version of the Raspberry Pi OS in order to use the latest version, is this correct?

That's correct. arm/v7 builds were very unpredictable and would fail all the time for seemingly no reason and would eat up developer time so we dropped support. Others have reported that using a 64bit OS on the Pi works great.

For folks already using their RPI to serve other apps, upgrading to 64 bit OS is not ideal. I encountered the error mentioned here when installing docker-compose on the RPI, but workaround was just to use --only-binary=cryptography . Could similar approach be used to fix the CI/CD so that we can restore availability of armv7 mealie images?

Edit: I suppose you may have tried already --only-binary flag , but since you use Poetry I am guessing due to this issue you don't have ability for this simple workaround that you would have if you used Pip instead
