summary

PostFinance built TOPF (Talos Orchestrator by PostFinance), a Go CLI that migrates kubeadm clusters to Talos and manages lifecycle tasks: bootstrapping, Go templating for per-node patches, secrets handling with in-place encryption plus Vault/1Password support, and rolling OS upgrades with parallelism (used on a ~100-node fleet with “5 at once” or percentage flags). It runs in GitLab pipelines, manages 35 production clusters (oldest seven years), shows one-minute bootstraps in live demo, and successfully completed ongoing migrations.
