Pi Zero - Unable to deploy with docker-compose

When trying to use docker-compose on a Raspberry Pi Zero it fails due not having a supported image.

Output of trying to run:

pi@raspberrypi:~/standard-notes/syncing-server $ docker-compose up -d

Happy to perform any tests, or if there's no plans for armv6 image that's okay as well.
