Python implementation of the Kubernetes KRM Function Interface

Kubed KRM

A python Implementation of KRM function by Kustomize and Google.

Random

Generate a random string or number and stamp it into target resource fields. Configure keepers and the value is deterministically derived from the keeper field values — same inputs, same output — like Terraform's random_string. Useful for getting a Job name that only changes when upstream values actually change (a workaround for Kustomize hashing ConfigMap names after all transformers have run).
