Here is your business justification: K8s / Helm charts have become the de-facto standard for packaging applications for on-premise deployments. If you choose any other deployment option on a setup/support contract, the supplier will likely charge you for additional hours.
This is also what we observe while building Distr. ISVs are in need for a container registry to hand over these images to their customers. Our container registry will be purpose build for this use-case.
