How to get this working on a raspberry pi

[Chief-T1]

Hi,

I've been trying to get this working on a raspberry pi. I've had numerous issues.
The first was related to the alpine linux version not working, related to this issue: nodejs/docker-node#1589.

I fixed this by changing the Dockerfiles build line to this: FROM node:18-alpine

I've now got issues with MongoDB not connecting and I am getting the following errors:

WARNING: MongoDB 5.0+ requires ARMv8.2-A or higher, and your current system does not appear to implement any of the common features for that!
  see https://jira.mongodb.org/browse/SERVER-55178
  see also https://en.wikichip.org/wiki/arm/armv8#ARMv8_Extensions_and_Processor_Features
  see also https://github.com/docker-library/mongo/issues/485#issuecomment-970864306
/usr/local/bin/docker-entrypoint.sh: line 414:    28 Illegal instruction     "${mongodHackedArgs[@]}" --fork

I've read online that I need to use an older version of MongoDB and so have changed the image in my docker compose file to use mongo:4.4. I'm still getting errors, can you please advise what else I need to change to get this to work?

The docker compose file I'm using is below:

version: "3.4"

services:
  mongo:
    image: mongo:4.4
    restart: always
    environment:
      MONGO_INITDB_ROOT_USERNAME: root
      MONGO_INITDB_ROOT_PASSWORD: root
    volumes:
      - mongo_db:/data/db

  backend:
    build:
      context: ./api
      dockerfile: ./Dockerfile
    volumes:
      - type: bind
        source: ./api
        target: /api
    depends_on:
      - "mongo"


  frontend:
    build:
      context: ./app
    depends_on:
      - "backend"


volumes:
  mongo_db:

Thank you

Hi there

What is the latest error message you are getting? I am not having any issues with the dockerfile as above 🤔

[Chief-T1]

I'm getting different variations of this error in a loop:

WARNING: MongoDB 5.0+ requires ARMv8.2-A or higher, and your current system does not appear to implement any of the common features for that! see https://jira.mongodb.org/browse/SERVER-55178 see also https://en.wikichip.org/wiki/arm/armv8#ARMv8_Extensions_and_Processor_Features see also https://github.com/docker-library/mongo/issues/485#issuecomment-970864306 /usr/local/bin/docker-entrypoint.sh: line 414: 28 Illegal instruction "${mongodHackedArgs[@]}" --fork

The variations are on the last line and are the following:

• '25 Illegal instruction'
• '26 Illegal instruction'
• '27 Illegal instruction'
• '28 Illegal instruction'

If I google it I come across issues like the below which seem to suggest the error is a result of mongo version 5 being unsupported on a raspberry pi. I've tried to change the compose file to use mongo:4.4 as the image but I'm not sure if there's anywhere else I should change this.

@Chief-T1,
Most likely this is due to the fact that MongoDB 5.0+ requires AVX instructions, have you tried removing optimizations for sandy bridge CPU's? You can look at my patch, where exactly this can be removed.

Hi @GermanAizek

Thank you for the help. I have to admit your page although very well written does look a bit too technical for me at first glance. I think I need a few days to really understand the process.

Just a couple quick questions:

• Is this a process I can move into docker? I get the impression that your how-to is aimed at installing on the host?
• Would sandy bridge optimisations still be an issue if I'm trying to use MongoDB 4.4 as my docker base image?

Thank you in advance.

@Chief-T1,
Thank you very much for idea, I can package this for you in dockerfile and build packages via Github Actions. I'll do it today, as soon as I notify you.

@GermanAizek,
Thank you so much, that would be really helpful! You're a legend!

I have the same problem. Did it work? How do I use this?

[GermanAizek]

@steiditi,
Use Dockerfile or rebuild with no-avx patch.

Hi all - apologies for the delay on this one - I have just released V2 of Recipe Buddy which removes the dependency on Mongo and should therefore run on a much wider range of devices - please do give it a go and let me know what you think :)
