Helm

Helm packages Kubernetes apps as charts: templates plus a values file, installed as a release you can upgrade or roll back. You will install a public chart, write your own, use hooks and subcharts, then look at signing, OCI registries, and what GitOps controllers actually render. Helm will not stop a privileged pod unless you add policy, and a values file is still a config surface.
