What's New in Talos 1.4
See also upgrade notes for important changes.
Talos now starts a text-based UI dashboard on virtual console
/dev/tty2 and switches to it by default upon boot.
Kernel logs remain available on
To switch between virtual TTYs, use the
You can disable this new feature by setting the kernel parameter
The dashboard is disabled by default on SBCs to limit resource usage.
The output to the serial console is not affected by this change.
Interactive Dashboard on QEMU VM
Talos now ships with the latest Linux LTS kernel 6.1.x.
GRUB Menu Wipe Options
Talos ISO GRUB menu now an includes an option to wipe completely a Talos installed on a system disk.
Talos GRUB menu for a system disk boot now includes an option to wipe
EPHEMERAL partition returning the
machine to the maintenance mode.
Talos now automatically loads kernel drivers built as modules. If any system extensions or the Talos base kernel build provides kernel modules and if they matches the system hardware (via PCI IDs), they will be loaded automatically. Modules can still be loaded explicitly by defining it in machine configuration.
At the moment only a small subset of device drivers is built as modules, but we plan to expand this list in the future.
Kernel Modules Tree
Talos now supports re-building the kernel modules dependency tree information on upgrades.
This allows modules of same name to co-exist as in-tree and external modules.
System Extensions can provide modules installed into
extras directory and when loading it’ll take precedence over the in-tree module.
Talos now supports passing environment variables via
talos.environment kernel argument.
Talos now supports specifying a list of system partitions to be wiped in the
talos.experimental.wipe kernel argument.
Bond Device Selectors
Bond links can now be described using device selectors instead of explicit device names:
machine: network: interfaces: - interface: bond0 bond: deviceSelectors: - hardwareAddr: '00:50:56:*' - hardwareAddr: '00:50:57:9c:2c:2d'
VLAN Machine Configuration
Strategic merge config patches now correctly support merging
.vlans sections of the network interface.
Talos adds new APIs to make it easier to perform etcd maintenance operations.
These APIs are available via new
talosctl etcd sub-commands:
talosctl etcd alarm list|disarm
talosctl etcd defrag
talosctl etcd status
See also etcd maintenance guide.
talosctl logs -k and
talosctl containers -k now support and output container display names with their ids.
This allows to distinguish between containers with the same name.
A dashboard now shows same information as interactive console (see above), but in a remote way over the Talos API:
talosctl dashboard CLI
Previous monitoring screen can be accessed by using
An issue was fixed which might lead to the log output corruption in the CLI under certain conditions.
Talos API was extended to support retrieving a list of network connections (sockets) from the node and pods.
talosctl netstat command was added to retrieve the list of network connections.
Talos now supports resetting user disks through the Reset API,
the list of disks to wipe can be passed using the
--user-disks-to-wipe flag to the
talosctl reset command.
Registry Mirror Catch-All Option
Talos now supports a catch-all option for registry mirrors:
machine: registries: mirrors: docker.io: - https://registry-1.docker.io/ "*": - https://my-registry.example.com/
Talos now supports a new
os:operator role for the Talos API.
This role allows everything
os:reader role allows plus access to maintenance APIs:
rebooting, shutting down a node, accessing packet capture, etcd alarm APIs, etcd backup, etc.
