tuppr

A Kubernetes controller for automated, orchestrated upgrades of Talos Linux and Kubernetes.

• You want the rollout orchestrated: health-gated, one plan at a time, with drain, reboot, and node-readiness verification handled for you.
• You want to keep the Kubernetes version in step through the same declarative flow.

When not to use it

• You need tuppr to pick a safe version for you. It upgrades to exactly the version you specify and does not enforce Talos’s sequential upgrade path - that is your…
