Bringing LTS To Kubernetes: Lessons From the Field
Talkat Open Source Summit Japan + AI_dev: Open Source GenAI & ML Summit + Automotive Linux Summit 2025 · 2025-12-08..12-10·
summary
Canonical packages upstream Kubernetes, releases an LTS every six upstream versions, and promises 10–15 years of security patches under Ubuntu Pro plus legacy, with FIPS-enabled Kubernetes and follow-the-sun SLAs for telco and regulated customers. Upgrades follow upstream GA, five interim releases are short-term maintainable, and there is a one-year grace period after a new LTS to migrate; managed upgrades and MicroK8s-to-Canonical-Kubernetes migration paths are offered and partner integrations (NVIDIA, BT, VMware) are already in production.
