Talos and k8s version mismatch preventing upgrades

I'm running talos 1.7.6 and kubernetes 1.32.0. I know talos 1.7.6 ships with kubernetes 1.30.3 and to be honest I have no idea how I got myself on 1.32.0. I'm almost certain I haven't run talosctl upgrade-k8s or anything similar although I accept there's good evidence to the contrary. More on github.com

How to update proxy settings for running cluster?

There's a caveat here - kube-proxy is a bootstrap manifest, it lives fully in Kubernetes. Talos by default doesn't update them, so you need to run talosctl upgrade-k8s to the same Kubernetes version to get things updated. More on github.com

r/kubernetes on Reddit: Upgrade cluster Talos

April 1, 2025 -

Hello everyone!
For those who have Talos clusters, how do you upgrade the installer?
I managed to upgrade from 1.7.6 to 1.7.7, but when upgrading from 1.7.7 to 1.8.0, the ETCD of the control planes no longer synchronizes correctly. I randomly lose access to the API across all my nodes.

Are you using a VIP for the API server? How many control plane nodes?

In my experience there are three things to keeping talos updated. Talos CLI (not sure if this is what you mean by upgrading the installer?) The node images and configuration Kubernetes 1. To update talosctl itself I use this: # removes old version of talos cli sudo rm /usr/local/bin/talosctl # download latest version of talos cli and installs it curl -sL https://talos.dev/install | sh 2. To patch the nodes with new images I use talosctl upgrade Here is an example with powershell to loop through selected nodes in the order that I like. The variable $mgmtVMs is just a list of vms from a csv file. # upgrade each node in the mgmt cluster to a new image, starting with control plane and then workers $upgradeList = $mgmtVMs | % { $p = "./node-patches/{0}/version.yaml" -f $_.Role $y = ConvertFrom-yaml (Get-Content $p -Raw) $IsoUrl = $y.machine.install.image [PSCustomObject]@{ IP = $_.IP Name = $_.Name IsoURL = $IsoUrl Role = $_.Role } } $upgradeList | Out-ConsoleGridView | Sort-Object Role, Id | % { "VM {0} started at {1} -- upgrade to {2}" -f $_.Name, (get-date -f 'HH:mm:ss'), $_.IsoURL talosctl upgrade --image $_.IsoURL --nodes $_.IP "{0} finished at {1}" -f $_.Name, (get-date -f 'HH:mm:ss') start-sleep 1 } Here is what that looks like if you are curious. https://i.imgur.com/KZbY2Wp.png 3. And of course to update kubernetes I would just use talosctl upgrade-k8s
