I agree but on the other hand I can't really deny how containery stuff offers a standard way of deploying and automation.

Maybe you want to run your application on Kubernetes? Nomad can just run an application directly, but I don't believe Kubernetes can.

In isolation there is no difference. In fact if rust or go apps are the only apps you deploy containers are probably overkill for you. But if you also deploy java/node/python/ruby then containers provide not just reproducible builds but a common deployment method that is language/framework agnostic. And the consistency is often worth it even if some of the deployments don't strictly need docker themselves.

Consistency is sometimes an underrated value but it can provide teams a lot of speedup when it's there.
