Multi-cloud networking for Kubernetes, simplified.
Galactic connects Kubernetes workloads across multiple clouds and regions as if they were on a single, unified network. It provides secure, isolated Virtual Private Clouds (VPCs) that span cloud boundaries—without vendor lock-in or complex configuration.
Modern organizations run workloads everywhere: AWS, Azure, GCP, on-premises, and edge locations. Each environment brings its own networking model, APIs, and constraints. The result is fragmented networks, operational complexity, and cloud provider lock-in.
Galactic provides the SRv6 data plane that makes multi-cloud VPC connectivity work at the kernel level. It runs as a DaemonSet agent on every node, managing SRv6 routes and VRF isolation, and as a CNI plugin that attaches pods to the correct virtual network. VPC and VPCAttachment definitions are managed by a companion operator; Galactic acts on the identifiers that operator assigns.
Under the hood, Galactic uses Segment Routing over IPv6 (SRv6) for efficient, deterministic routing and Virtual Routing and Forwarding (VRF) for true network isolation at the kernel level. BGP is used to distribute SRv6 routes between agents across nodes and clusters.
For Developers — Attach to a VPC with a single annotation. No networking code, no cloud-specific APIs.
For Platform Teams — Manage multi-cloud networking from Kubernetes using GitOps workflows and standard tooling.
For Organizations — Move workloads between providers without network redesign. One networking model instead of N cloud-specific implementations.
Two ContainerLab environments are available under lab/:
lab/network/— Standalone SRv6 underlay lab (FRR + GoBGP, no Kubernetes). Good starting point for understanding the routing layer.lab/gvpc/— Three Kind clusters wired over an SRv6 transit mesh. The full GVPC multi-cluster environment.
See the DevContainer for development environment setup.
This project uses Task as its build tool. All build, test, lint, and lab operations are defined in Taskfile.yaml files at the repo root and under each lab/ subdirectory.
