The Humanitec Platform Orchestrator allows for seamless integration with Kubernetes clusters without the need to make them public. For private clusters, the Humanitec Agent is utilized, which establishes a secure tunnel within the private network, ensuring no new port exposure. The Agent is easy to install and can be combined with the Humanitec Operator for secret storage within the private network. To learn more about this process, refer to the documentation or schedule a call with a platform architect.
