Clément Nussbaumer - TOPF: Open Sourcing PostFinance's Tool to Migrate and Manage Talos Linux Cl

"Join us as we walk through our migration journey from kubeadm to Talos Linux at PostFinance, and learn about the tooling we built and open-sourced along the way: TOPF (Talos Orchestrator by PostFinance). TOPF is a Go tool that manages the full lifecycle of Talos-based Kubernetes clusters - from bootstrapping and config management with pre-flight checks and dry-run diffs, to rolling Talos OS upgrades across nodes. Its layered YAML patch model keeps configuration DRY and makes pull request reviews straightforward, whether you're managing one cluster or many environments. We'll demo the tool, show how we use it in our GitLab pipelines for day-2 operations, and share honest lessons from an ongoing migration at a financial institution. Whether you're running a homelab or managing on-prem clusters at scale, you'll walk away with concrete ideas for bringing the same discipline to your infrastructure."
