MongoDB not supported by CPU

Is this a new feature request?

Wanted change

I tried switching to Unifi Network Application, and tried to set up MongoDB. Unfortunately at bootup I get the message, that MongoDB is not supported by my CPU:

WARNING: MongoDB 5.0+ requires a CPU with AVX support, and your current system does not appear to have that!
  see https://jira.mongodb.org/browse/SERVER-54407
  see also https://www.mongodb.com/community/forums/t/mongodb-5-0-cpu-intel-g4650-compatibility/116610/2
  see also https://github.com/docker-library/mongo/issues/485#issuecomment-891991814

Are there any other way to use the new controller docker?

My server is around 3-4 years old. I think there must be more people unable to run MongoDB. Maybe consider supporting other databases.

Reason for change

I can't be the only one with this issue.

Proposed code change

You're not the only one but it is what it is. It's a mongodb restriction and the links provided in the log entry explain what it is. Nothing we can do.

For anyone else encountering this issue on ARM (specifically I am running on a Raspberry Pi 4), the version 4.4.18 of MongoDB still runs and seems to be compatible with UniFi Network Application. The message on ARM is the following

WARNING: MongoDB requires ARMv8.2-A or higher, and your current system does not appear to implement any of the common features for that!
  applies to all versions ≥5.0, any of 4.4 ≥4.4.19

It seems that arm64v8/mongo:4.4.18 works fine. Here's my full docker compose for the stack (with omitted password and init-mongo.js):

On my X64 machine I used docker tag mongo:4.4.6 to make it work in the end. This seems to be the last version without required AVX support as far as I heard.

WOW thanks,m this worked on my Raspberry Pi 4 2gb running Raspberry Pi OS 64 bit,

[ramonpaolo]

The MongoDB now can be run in the Raspberry Pi 5(with 4GB or 8GB), because the processor of Raspberry Pi 5 is the ARM Cortex-76, that are the ArmV8.2 that supports the AVX
