It can be very helpful for complex deployments.

For example, if you want to deploy a distributed TensorFlow training on kubernetes with multiple parameter servers and task servers, it is a nightmare to do just with kubernetes yaml templates. Helm and it's go templating makes it much much easier.

We've standardized on helm for prod deploys. Perhaps it's not a huge value, but it is a convenient way to bundle together a set of configs, templatize them and manage them.

Seconded. We use Helm to deploy OpenStack (and various supporting services) on Kubernetes: https://github.com/sapcc/helm-charts and https://github.com/sapcc/openstack-helm

I don't think we could live without helm charts. There are so many moving parts, and developers, it really makes life far easier.

Of course I made this comment today, and have spent the last hour trying to fix an issue. Funny how life works like that :)
