Upgrading Talos Linux - Sidero Documentation
This scheme retains the previous Talos kernel and OS image following each upgrade. If an upgrade fails to boot, Talos will roll back to the previous version. Likewise, Talos may be manually rolled back via API (or talosctl rollback), which will update the boot reference and reboot.

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

January 21, 2025 - Talos recommends using the talosctl upgrade-k8s command which automatically upgrades the entire cluster and has built in safety checks. They explain how to do it manually, but I chose Talos Linux partly based on the ease of ongoing maintenance and upgrades so I will be using the easy button here!

This command acts as a simple wrapper for talosctl upgrade-k8s. It only requires one node to initiate the upgrade process, after which it uses Talos discovery to locate all other nodes and upgrade them in sequence.
