Configuration

Package v1alpha1 configuration file contains all the options available for configuring a machine.

To generate a set of basic configuration files, run:

talosctl gen config --version v1alpha1 <cluster name> <cluster endpoint>

This will generate a machine config for each node type, and a talosconfig for the CLI.

Config

Config defines the v1alpha1 configuration file.

version: v1alpha1
persist: true
machine: # ...
cluster: # ...

version string

Indicates the schema used to decode the contents.

Valid values:

  • v1alpha1

debug bool

Enable verbose logging to the console. All system containers logs will flow into serial console.

Note: To avoid breaking Talos bootstrap flow enable this option only if serial console can handle high message throughput.

Valid values:

  • true

  • yes

  • false

  • no

persist bool

Indicates whether to pull the machine config upon every boot.

Valid values:

  • true

  • yes

  • false

  • no

machine MachineConfig

Provides machine specific configuration options.

cluster ClusterConfig

Provides cluster specific configuration options.

MachineConfig

MachineConfig represents the machine-specific config values.

Appears in:

type: controlplane
# InstallConfig represents the installation options for preparing a node.
install:
    disk: /dev/sda # The disk used for installations.
    # Allows for supplying extra kernel args via the bootloader.
    extraKernelArgs:
        - console=ttyS1
        - panic=10
    image: ghcr.io/talos-systems/installer:latest # Allows for supplying the image used to perform the installation.

    # diskSelector:
    #     size: 4GB # Disk size.
    #     model: WDC* # Disk model `/sys/block/<dev>/device/model`.

type string

Defines the role of the machine within the cluster.

Init

Init node type designates the first control plane node to come up. You can think of it like a bootstrap node. This node will perform the initial steps to bootstrap the cluster – generation of TLS assets, starting of the control plane, etc.

Control Plane

Control Plane node type designates the node as a control plane member. This means it will host etcd along with the Kubernetes master components such as API Server, Controller Manager, Scheduler.

Worker

Worker node type designates the node as a worker node. This means it will be an available compute node for scheduling workloads.

Valid values:

  • init

  • controlplane

  • join

token string

The token is used by a machine to join the PKI of the cluster. Using this token, a machine will create a certificate signing request (CSR), and request a certificate that will be used as its’ identity.

Warning: It is important to ensure that this token is correct since a machine’s certificate has a short TTL by default.

Examples:

token: 328hom.uqjzh6jnn2eie9oi

ca PEMEncodedCertificateAndKey

The root certificate authority of the PKI. It is composed of a base64 encoded crt and key.

Examples:

ca:
    crt: TFMwdExTMUNSVWRKVGlCRFJWSlVTVVpKUTBGVVJTMHRMUzB0Q2sxSlNVSklla05DTUhGLi4u
    key: TFMwdExTMUNSVWRKVGlCRlJESTFOVEU1SUZCU1NWWkJWRVVnUzBWWkxTMHRMUzBLVFVNLi4u

certSANs []string
