Kubernetes is an open-source platform for automating the deployment, scaling, and management of containerized applications. For security, it can encrypt sensitive data, such as Secrets, at rest. This functionality relies on an external Key Management Service (KMS) to handle the encryption and decryption. When integrated with the ESKM, Kubernetes can leverage a centralized and secure service for these cryptographic operations. This ensures enhanced security and helps meet regulatory compliance requirements for sensitive data within your cluster.
