v1alpha1

Package v1alpha1 contains definition of the v1alpha1 configuration document.

Even though the machine configuration in Talos Linux is multi-document, at the moment this configuration document contains most of the configuration options.

It is expected that new configuration options will be added as new documents, and existing ones migrated to their own documents.

1 - Config

Config defines the v1alpha1.Config Talos machine configuration document.
version: v1alpha1
machine: # ...
cluster: # ...
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 controlplane 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.

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.

Used to provide static pod definitions to be run by the kubelet directly bypassing the kube-apiserver.
Static pods can be used to run components which should be started before the Kubernetes control plane is up.
Talos doesn’t validate the pod definition.
Updates to this field can be applied without a reboot.

disks[]MachineDisk
Used to partition, format and mount additional disks.Since the rootfs is read only with the exception of /var, mounts are only valid if they are under /var.
Note that the partitioning and formatting is done only once, if and only if no existing XFS partitions are found.
If size: is omitted, the partition is sized to occupy the full disk.
Show example(s)
disks:
    - device: /dev/sdb # The name of the disk to use.
      # A list of partitions to create on the disk.

files[]MachineFile
Allows the addition of user specified files.The value of op can be create, overwrite, or append.
In the case of create, path must not exist.
In the case of overwrite, and append, path must be a valid file.
If an op value of append is used, the existing file will be appended.
Note that the file contents are not required to be base64 encoded.
Show example(s)

registriesRegistriesConfig
Used to configure the machine’s container image registry mirrors.
Automatically generates matching CRI configuration for registry mirrors.

The mirrors section allows to redirect requests for images to a non-default registry,
which might be a local registry or a caching mirror.

The config section provides a way to authenticate to the registry with TLS client
identity, provide registry CA, or authentication information.
Authentication information has same meaning with the corresponding field in .docker/config.json.

See also matching configuration for CRI containerd plugin.

machine:
    network:

FieldTypeDescriptionValue(s)
enabledbool
Enable the KubeSpan feature.Cluster discovery should be enabled with .cluster.discovery.enabled for KubeSpan to be enabled.
advertiseKubernetesNetworksbool
Control whether Kubernetes pod CIDRs are announced over KubeSpan from the node.If disabled, CNI handles encapsulating pod-to-pod traffic into some node-to-node tunnel,
and KubeSpan handles the node-to-node traffic.
If enabled, KubeSpan will take over pod-to-pod traffic and send it over KubeSpan directly.
When enabled, KubeSpan should have a way to detect complete pod CIDRs of the node which
is not always the case with CNIs not relying on Kubernetes for IPAM.
allowDownPeerBypassbool
Skip sending traffic via KubeSpan if the peer connection state is not up.This provides configurable choice between connectivity and security: either traffic is always
forced to go via KubeSpan (even if Wireguard peer connection is not up), or traffic can go directly
to the peer if Wireguard connection can’t be established.
harvestExtraEndpointsbool
KubeSpan can collect and publish extra endpoints for each member of the clusterbased on Wireguard endpoint information for each peer.
This feature is enabled by default to help discover additional endpoints,
but with high number of peers (>50) in the KubeSpan network it can cause performance issues.
mtuuint32
KubeSpan link MTU size.Default value is 1420.
