Definition

Submariner is an open-source tool designed to facilitate network connectivity between Kubernetes clusters across different networks, such as those in different cloud providers or on-premises environments. It enables seamless communication between services in separate clusters by creating a secure overlay network, allowing for multi-cluster service discovery and communication without requiring complex network configurations.
