Specifying basing on i386/i686 container in Dockerfile for usage in Docker on amd64
Distros, e.g. Ubuntu, do offer base images in multiple architectures; in fact, the specification of multi-arch images is now part of docker manifest file format.
Anyway, for CI builders, I'd need to automatedly build and run an 32bit docker image on a 64 bit machine.
I just can't seem to figure out how to specify in a Dockerfile that I want the i686 architecture variant of the ubuntu base in my FROM ubuntu:18.04 line.
(same, by the way, goes for Fedora images.)
For clarification: I'm not looking for info like FROM i386/ubuntu, or that I can build FROM scratch and ADD a 32bit tar.
I want to know how I can tell FROM that I mean the xyz architecture of a multiarch Dockerhub repo, so, I'm looking for something that does (I hope I get the idea across)
FROM ubuntu:18.04:arch=xyz
docker dockerfile 32bit-64bit
