Nodes on any network or cloud provider can securely join an existing cluster.
KubeSpan is integrated into Talos Linux, the operating system designed for Kubernetes. Talos Linux is secure, image based, immutable, and API managed. It installs hardened vanilla Kubernetes configured per the CIS guidelines.
Make your Kubernetes deployments secure, stable and simple with Talos Linux – and you’ll be ready for KubeSpan.
Unlike Cilium’s ClusterMesh, KubeSpan operates outside of Kubernetes and is deeply integrated within Talos itself. It works with any CNI or even no CNI. It works even when Kubernetes itself is broken. KubeSpan is a highly-reliable connectivity system with many layers of privacy and security built in, from the ground up.
If you are running your clusters on Talos Linux, extending them to other networks or cloud providers is as easy as enabling a configuration setting.
All cluster members will find each other, and securely and transparently establish full encryption. And you retain full control over your cluster!
