Unsupported platform when deploying via docker swarm

I'm receiving an error from docker swarm when this container starts.

no suitable node (unsupported platform)

The nodes are running intel x64 processors w/ an x64 kernel on debain 10. Before taking a deep dive into the container, I was wondering if you've run into this as well.

Here's my compose file, for reference, if you want to try it yourself. (Since, presumably, most of us run a similar cpu/kernel.) I believe the issue is specific to docker swarm, after digging a bit.
