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: # ...

FieldTypeDescriptionValue(s)
versionstringIndicates the schema used to decode the contents.v1alpha1
debugbool
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.

FieldTypeDescriptionValue(s)
typestring
Defines the role of the machine within the cluster.
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.

This node type was previously known as “join”; that value is still supported but deprecated.

worker
tokenstring
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.
Show example(s)
token: 328hom.uqjzh6jnn2eie9oi
caPEMEncodedCertificateAndKey
The root certificate authority of the PKI.It is composed of a base64 encoded crt and key.
