We are excited to announce the soft release of Sylva V1.2, an open-source reference implementation designed for managing large volumes of Kubernetes clusters. The Sylva stack utilizes a declarative approach for managing the lifecycle of different kubernetes distributions, through ClusterAPI and FluxCD. It enables seamless deployment, upgrading, and scaling of Kubernetes clusters without the need for extensive scripting. Our GITOPS workflow ensures guaranteed target deployments.
Key Highlights of Sylva V1.2:
Production Readiness
Sylva V1.2 continues our commitment to production deployment quality, thanks to a good level of testing in multiple CI environments (Openstack, VMWare emulated Bare Metal hosted at Equinix). It aligns with Kubernetes Release V1.29 to ensure support from the CNCF community and IT vendors. This release has been developed collaboratively by a dedicated team of 50 developers.
Operational Enhancements
This release addresses many improvements on operational tooling, it integrates a federated view of logging and monitoring using Loki, Thanos, Grafana, and Prometheus for effective management of Kubernetes clusters and Bare Metal environments.
Improved Documentation
We have increased our documentation especially to provide a better onboarding experience for newcomers. Explore the updated resources.
Advanced Security Features
Sylva is committed to implementing advanced security mechanisms in line with DevSecOps design as described by the SLSA framework and EUCS recommendations. This release integrates security enforcement and introduces enhanced integrity verification for the container registry artifacts (OCI artifacts), with a particular focus on OS images, container images, Helm charts.
New Features
In response to the growing convergence of IT and network functions, Sylva V1.2 enhances lifecycle management for Kubevirt, supporting both virtual machines and containers through GitOps deployment and upgrades.
Additionally, our Workgroup-04 on Sustainability, led by Huamin Chen from Red Hat, has tested Kepler to monitor energy consumption across network functions. Now it is fully incorporated into Sylva’s lifecycle management and monitoring.
Future Developments
Looking ahead, we are excited to announce the integration of OpenShift OKD as a new Kubernetes distribution alongside K8S Vanilla and RKE2, allowing for automatic spawning of OpenShift clusters. Future releases will include upgrade and scaling capabilities.
