Another step toward seamless multi-cluster Kubernetes!

The fourth major release of Liqo is out and includes new exciting features:

• Reduced infrastructure requirements for easier peering. All the Liqo control plane traffic can flow through the Liqo-managed VPN tunnel already established between clusters at the beginning of the peering process. This leads to reduced infrastructure-level requirements and improved security, avoiding the necessity to expose the API Server on the public Internet, while supporting clusters behind NATs and/or firewalls (e.g., at the edge). The entire configuration is supported by a brand new liqoctl connect command.
• Introduce the support for cross-cluster persistent storage. Liqo is able to offload workloads that require persistent volumes, leveraging a custom virtual storage class. It abstracts the creation of the real PVCs in the remote clusters, and it ensures that mounting pods will be scheduled in the appropriate location. Additionally, liqoctl offers the possibility to easily move these volumes to a different cluster, hence facilitating stateful pod migration across clusters.
• Improved UX. Forget about long, hard-to-remember alphanumeric identifiers for remote clusters. A simplified naming system allows to easily correlate nodes and resources with the underlying clusters. Furthermore, new liqoctl commands simplify the interaction with Liqo, while providing at the same time richer feedback to the user.
