Logical operators for container requirements?

Product support
1

I’m looking to support a multi-device type fleet, with a variety of raspberry pi and jetson nano devices.

I wanted to use container requirements to specify that:

jetson nanos should get container-t210
jetson xaviers should get container-t186
and everything else should get container-base

Using Optional containers, I was able to do the first two, but it seems like I need a “NOT” operator to specify the 3rd, base case? Is it possible to do this?

I’d want to specify something like:

version: '2'
services:
  container-nano:
    build: ./t210
    labels:
      io.balena.features.requires.hw.device-type: 'jetson-nano'
      io.balena.features.optional: '1'
  container-xavier:
    build: ./t186
    labels:
      io.balena.features.requires.hw.device-type: 'jetson-xavier-nx'
      io.balena.features.optional: '1'
  container-base:
    build: ./base
    labels:
      io.balena.features.requires.hw.device-type: !='jetson.*'
      io.balena.features.optional: '1'
