FeaturesConfig describes individual Talos features that can be switched on or off. machine: features: rbac: true # Enable role-based access control (RBAC). # # Configure Talos API access from Kubernetes pods. # kubernetesTalosAPIAccess: # enabled: true # Enable Talos API access from Kubernetes pods.

December 15, 2025 - Talos machine configuration is fully documented: https://docs.siderolabs.com/talos/v1.12/reference/configuration/overview

March 3, 2026 - # Extract machine config from a control plane node # talosctl get returns a COSI resource wrapper, so use yq to extract the spec # (the actual machine config) for a file that can be re-applied later talosctl get machineconfig --nodes <cp-node-ip> -o yaml | yq eval '.spec' - > cp-node-1-config.yaml # Extract from a worker node talosctl get machineconfig --nodes <worker-node-ip> -o yaml | yq eval '.spec' - > worker-node-1-config.yaml

May 6, 2026 - Documentation for the talos.machine.getConfiguration function with examples, input properties, output properties, and supporting types.

It can be configured in the machine config like the following: machine: network: interfaces: - interface: br0 bridge: stp: enabled: true interfaces: - eth0 - eth1 · See documentation for more details.

machine_secrets (Attributes) The secrets for the talos cluster (see below for nested schema) machine_type (String) The type of machine to generate the configuration for

April 17, 2026 - First, let’s consider configuration using *talosctl*. Before applying the config, ensure it includes network settings for your node; otherwise, after reboot, the node won’t configure networking. During installation, the bootloader is written to disk and does not contain the `ip` option for kernel autoconfiguration. Here’s an example of a config patch containing the necessary values: ``` graf # node1.yaml machine: install: disk: /dev/sda network: hostname: node1 nameservers: - 1.1.1.1 - 8.8.8.8 interfaces: - interface: eno2np0 addresses: - 10.0.0.131/24 routes: - network: 0.0.0.0/0 gateway: 10.0.0.1

mkdir data docker run --rm -t -v $PWD/data:/app/data:ro \ -p 8080:8080 ghcr.io/siderolabs/talos-remote-config:latest · In a separate terminal run booter to PXE boot machines configured to use your host as a remote config endpoint.

May 13, 2025 - Before the cluster can form it needs to be bootstrapped - I applied the node configuration to the first node and then bootstrapped the cluster. Again talhelper gives the command we need: talhelper gencommand apply --extra-flags --insecure talosctl apply-config --talosconfig=./clusterconfig/talosconfig --nodes=192.168.1.1 --file=./clusterconfig/home-cluster-cp1.yaml; talhelper gencommand bootstrap talosctl bootstrap --talosconfig=./clusterconfig/talosconfig --nodes=192.168.1.1;

March 3, 2026 - # View the full effective configuration talosctl get machineconfig --nodes 192.168.1.10 -o yaml # Check a specific section talosctl get machineconfig --nodes 192.168.1.10 -o yaml | grep -A 20 "apiServer"

To make it even better, deploy a self-hosted instance of Omni to manage the Talos nodes. Gives you a nice interface to handle rolling out config patches, rolling Talos and k8s updates, scaling up and down, and integrating with infrastructure providers to automatically provision machines.

March 3, 2026 - At its simplest, talosctl gen config takes two required arguments: a cluster name and the Kubernetes API endpoint URL. # Generate machine configurations talosctl gen config my-cluster https://192.168.1.100:6443

March 6, 2025 - $ talosctl gen secrets --from-controlplane-config controlplane.yaml · This will generate a secrets.yaml file which you can then use to generate a new talosconfig file. Note that the cluster name and endpoint don’t matter here - they’re only used for generating machine configs.
