Raspbery Pi4 B mongoDB requires ARMv8.2-A or higher

[KohPilot]

What features would you like to see added?

Hi, I tried to install libreChat on my Umbrel server since it was available on the App store and it seems it's not working on my raspberry Pi 4b 8Gb. After analyzing logs, it seems mongoDB requires ARMv8.2-A or higher.

Since I'm not a linux Guru, and because I don't want to destroy my umbrel config i was wondering if it was possible to add a feature to detect on which architecture the umbrel server is running and adapt the MongoDB version accordingly (mongo:4.4.18 for Raspberry Pi 4b according to this article : #93).

Thanks !

Thanks for the suggestion, you're right about the MongoDB ARM compatibility issue on Pi 4B.

We can explore creating platform-specific Docker Compose files as a solution:

• docker-compose.yml (default for x86_64)
• docker-compose.arm.yml (ARM version with mongo:4.4.18)

This maybe could allow Umbrel's app store to automatically detect Pi hardware and use the appropriate compose configuration, giving you a working setup out of the box.

In the meantime, you can manually override the MongoDB version by using a docker-compose.override.yml file:

services:
  mongodb:
    image: mongo:4.4.18

I'll try it out now. Thanks !

Ok since Umbrel version create volumes with the Mongodb 5 version during the install, even though I add the override file I still get some errors. I tried to delete the umbrel/app-data/librechat/data/db files killed the container and restarted it but didn't work out.

I guess i'll wait for your fix so everything works from the install.
