I assume OP meant something like this, building the image on the remote host directly using a docker context (which is different from a build context)

  docker context create my-awesome-remote-context --docker "host=ssh://user@remote-host"

  docker --context my-awesome-remote-context build . -t my-image:latest

This way you end up with `my-image:latest` on the remote host too. It has the advantage of not transferring the entire image but only transferring the build context. It builds the actual image on the remote host.

This is exactly what I do, make a context pointing to the remote host, use docker compose build / up to launch it on the remote system.
