Modern environments aim to support today's security needs. Container orchestration frameworks offer the provisioning of software proxy servers and gateways that expose the service; for example, Kubernetes ingress resources, as well as OpenShift routes support TLS encryption for cluster-external traffic.

In order to provide secret values such as credentials or private keys, orchestration frameworks offer the functionality of secrets. As seen previously, this enables us to separately provide secret configurations into the environment. Chapter 5, Container and Cloud Environments with Java EE examined how this is realized.

This enables applications, as well as the configuration in general, to use secret values. The secrets can be injected into the container runtimes, if needed.
