Rancher Labs Submariner Project Links Kubernetes Clusters

March 12, 2019 / SDxCentral

Rancher Labs bolstered its open source credentials with the launch of its Submariner project aimed at providing network connectivity between Kubernetes clusters. This includes clusters running across cloud environments and on private, on-premises infrastructure. Sheng Liang, CEO and co-founder of Rancher Labs, explained that Submariner creates the necessary tunnels and routes between Kubernetes clusters that allow for direct connections regardless of their location. It can be deployed into existing Kubernetes clusters with the addition of Layer-3 network connectivity between pods in different clusters. The project also secures those connection paths using IPSec tunnels, though Rancher Labs does plan to add different interconnectivity plugins. Liang said this includes additional remote connectivity plugins for WAN-optimized or SD-WAN technologies.
