Is it possible to run duffle bundles on my kubernetes cluster right now? Couldn't find any docs. Thanks!

Yea absolutely. Check out the hellohelm bundle for a simple example: https://github.com/deislabs/bundles/tree/master/hellohelm and the Bitnami Wordpress + Amazon RDS bundle for one with multiple components: https://github.com/bitnami/cnab-bundles/tree/master/wordpres...

What would be the advantage over just using helm directly? (not a criticism, I'm not a big helm user for now, just kubectl but would like to know the difference for future project). Do you plan to integrate CNAB into kubernetes directly so we can bypass helm in the future?

If you're only using Kubernetes, straight Helm might be a better fit.

But imagine you need to run your Helm chart on Kubernetes environment that doesn't have access to your container images. You could build a thick bundle from your Helm chart, put it on USB stick, sneaker-net it over to a disconnected Kubernetes cluster, hydrate a container registry and run the Helm chart with full fidelity in the new environment.

This is just one thing CNAB enables..
