The 2-4GB RAM isn’t a hard requirement in my experience. I initially had the whole Docker compose stack running on a single $5 DigitalOcean droplet, and didn’t experience any issues for personal usage. Since they also distribute it to you as Docker containers, you can also set resource limits, specifically for the MSSQL container, to prevent it from hogging all the RAM.
I currently have my Bitwarden instance hosted on my Docker swarm cluster, which is just 3 $5 DO droplets and 1 with like 2GB and RAM and 2vCPUs. But, a quick look shows that currently all the BW containers are running on the $5 ones. I have the MSSQL container’s RAM limited to 1GB as well.
As for the x86 requirement, that’s likely the case, I’m assuming you mentioned it because you’d like to run it on some ARM device like a RPi. I haven’t tried running their containers on an ARM device so I can’t say they’ll be compatible, but I know docker’s ARM compatibility has improved so maybe someone has got them running on some ARM device.
