Starting a small Proof of Concept (PoC) with hybrid nodes can be challenging because hybrid nodes require network connectivity between the remote network (where you’re deploying your worker nodes) and the cluster Virtual Private Cloud (VPC). Additionally, you may have trouble finding enough physical hardware or virtual machines to adequately test hybrid nodes. To address these challenges, we created the containerized hybrid nodes project. The project is a proof of concept that allows you to quickly run a hybrid node as a container on a modestly equipped laptop. Connectivity between the remote network, i. e. your laptop, and the cluster VPC is established through a Tailscale network. For now, think of the Tailscale network as an encrypted peer to peer mesh network. Once network connectivity is established, you can run a containerized hybrid node and begin scheduling workloads onto it.
