Kubernetes Upgrade

[!WARNING] Make sure to upgrade the Talos CLI before proceeding. “It is advisable to use the same version of talosctl as the version of the boot media used.” - Talos Docs

Upgrade Path

  1. From 1.30.3 to 1.30.5
  2. From 1.30.5 to 1.31.1

[!NOTE] To trigger a Kubernetes upgrade, issue a command specifying the version of Kubernetes to upgrade to, such as: talosctl –nodes upgrade-k8s –to 1.30.0 Note that the –nodes parameter specifies the control plane node to send the API call to, but all members of the cluster will be upgraded. To check what will be upgraded you can run talosctl upgrade-k8s with the –dry-run flag

k cnp maintenance set --all-namespaces
kubent
talosctl --nodes $TALOS_CP -e $TALOS_CP upgrade-k8s --to 1.31.1 --dry-run
talosctl --nodes $TALOS_CP -e $TALOS_CP upgrade-k8s --to 1.31.1
