Thanks, hadn't heard of that.

Seems pretty active per its commit activity: https://github.com/hashicorp/nomad/graphs/commit-activity

But the fact that I hadn't heard of it before makes it sound not very popular, at least not for the bubble I live in :).

Does anyone have any practical experiences to share about it?

Yes have a few Nomad clusters in production and it's been great.

You'll certainly want to combine it with Consul and use Consul templates and service discovery though.

I'd say the difficulty and complexity level is between Kubernetes and Docker Swarm, not having to use YML too is a big benefit imho.
