What is Liqo?
Liqo is an open-source project that enables dynamic and seamless Kubernetes multi-cluster topologies, supporting heterogeneous on-premise, cloud and edge infrastructures.
What does it provide?
- Peering: automatic peer-to-peer establishment of resource and service consumption relationships between independent and heterogeneous clusters. No need to worry about complex VPN configurations and certification authorities: everything is transparently self-negotiated for you.
- Offloading: seamless workloads offloading to remote clusters, without requiring any modification to Kubernetes or the applications themselves. Multi-cluster is made native and transparent: collapse an entire remote cluster to a virtual node compliant with the standard Kubernetes approaches and tools.
- Network fabric: transparent multi-cluster pod-to-pod and pod-to-service connectivity, regardless of the underlying configurations and CNI plugins. Natively access the services exported by remote clusters, and spread interconnected application components across multiple infrastructures, with all cross-cluster traffic flowing through secured network tunnels.
- Storage fabric: support for remote execution of stateful workloads, according to the data gravity approach. Seamlessly extend standard (e.g., database) high availability deployment techniques to the multi-cluster scenarios, for increased guarantees. All without the complexity of managing multiple independent cluster and application replicas.
Quick start
Would you like to quickly join the fray and experiment with Liqo? Set up your playground and check out the getting started examples, which will guide you through a scenario-driven tour of the most notable features of Liqo:
- Quick Start: grasp a quick overview of what Liqo can do.
- Offloading with Policies: discover how to tune namespace offloading, and how to use policies to select which clusters may host each workload.
- Offloading a Service: learn how to create a multi-cluster service, and how to consume it from each connected cluster.
- Stateful Applications: find out how to deploy a database across a multi-cluster environment, leveraging the Liqo storage fabric.
- Global Ingress: discover how route external traffic to multi-cluster applications through a global ingress and automatic DNS configurations.
- Replicated Deployments: learn how to deploy an application by replicating it on multiple remote clusters.
- Provision with Terraform: explore Liqo Terraform provider capabilities.
