Submariner enables direct networking between pods and services in different Kubernetes clusters, either on-premise or in the cloud.

Why Submariner?

As Kubernetes gains adoption, teams are finding they must deploy and manage multiple clusters to facilitate features like geo-redundancy, scale, and fault isolation for their applications. With Submariner, your applications and services can span multiple cloud providers, data centers, and regions.

Submariner is completely open source and designed to be network- plugin (CNI) agnostic.

What Submariner provides:

Cross-cluster L3 connectivity using encrypted VPN tunnels
Service discovery across clusters
subctl, a friendly deployment tool
Support for interconnecting clusters with overlapping CIDRs
Oleg Chunikhin, Co-Founder and CTO at Kublr, will present an overview and a demo of the submariner project.
