This is partially true. If the only feature you care about Kubernetes is container scheduling, then yes, Nomad is simpler. The same could probably be said about Docker Swarm. However, if you want service discovery, load balancing, secret management, etc., you'll probably need Nomad+Vault+Consul+Fabio/similar to get all the basic features. Want easy persistent storage provisioning? Add CSI to the mix.

Configuring these services to work together is not all trivial either (considering proper security, such as TLS everywhere) and there aren't many solutions available from the community (or managed) that package this in an easy way.

While this is not false, I don't think many of the posts critical of K8s hitting the front page are advertising for Nomad, or focusing on drawbacks that don't apply to Nomad.
