Can a Helm Install create a container from a dockerfile?
No. A helm chart is a templated set of kubernetes manifests. There will usually by a manifest for a Pod, Deployment, or Daemonset. Any of those will have a reference to a docker image (either hard coded or a parameter). That image will usually be in a container registry like dockerhub. You'll need to build your image using the docker file, push it to a registry, reference this image in a helm chart, then install or update helm.
