I just see that we can make a rpi cluster with docker swarm.
Like it’s not possible to make my own selfhosted server with discourse and a single raspberry 3 because discourse need 2 Gb of RAM… is that possible to install discourse on this kind of config? For example with 2 or 4 rpi3?
Is that a function of a cluster?

You could potentially split Discourse up into enough little pieces, but you’d need to build your own ARM-based Docker image, as we only ship (and support) an amd64-based image.
