Kubernetes Entrypoint

The kubernetes-entrypoint image is built from ContainerFiles/kubernetes-entrypoint. Security patches are applied by scripts/kubernetes-entrypoint-cve-patching.sh.

This container packages the Kubernetes Entrypoint service for use in the stack. The build installs the required packages, applies security updates and configuration, and prepares the service for integration.
