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
1 - Config
Config defines the v1alpha1.Config Talos machine configuration document.

type | string | 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. | controlplaneworker |
token | string | The Using this token, a machine will create a certificate signing request (CSR), and request a certificate that will be used as its’ identity. | |
ca | PEMEncodedCertificateAndKey | The root certificate authority of the PKI.It is composed of a base64 encodedcrt and key.Show example(s) | |
acceptedCAs | []PEMEncodedCertificate | The certificates issued by certificate authorities are accepted in addition to issuing ‘ca’.It is composed of a base64 encoded `crt``. | |
certSANs | []string | Extra certificate subject alternative names for the machine’s certificate.By default, all non-loopback interface IPs are automatically added to the certificate’s SANs.Show example(s) | |
controlPlane | MachineControlPlaneConfig | Provides machine specific control plane configuration options. Show example(s) | |
kubelet | KubeletConfig | Used to provide additional options to the kubelet. Show example(s) | |
pods | []Unstructured | 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. See https://kubernetes.io/docs/tasks/configure-pod-container/static-pod/. Show example(s) | |
network | NetworkConfig | Provides machine specific network configuration options. Show example(s) | |
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) | |
install | InstallConfig | Used to provide instructions for installations.Note that this configuration section gets silently ignored by Talos images that are considered pre-installed. To make sure Talos installs according to the provided configuration, Talos should be booted with ISO or PXE-booted. Show example(s) | |
files | []MachineFile | Allows the addition of user specified files.The value ofop 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) | |
env | Env | The All environment variables are set on PID 1 in addition to every service. | GRPC_GO_LOG_VERBOSITY_LEVELGRPC_GO_LOG_SEVERITY_LEVELhttp_proxyhttps_proxyno_proxy |
time | TimeConfig | Used to configure the machine’s time settings. Show example(s) | |
sysctls | map[string]string | Used to configure the machine’s sysctls. Show example(s) | |
sysfs | map[string]string | Used to configure the machine’s sysfs. Show example(s) | |
registries | RegistriesConfig | 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 clientidentity, 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. Show example(s) | |
systemDiskEncryption | SystemDiskEncryptionConfig | Machine system disk encryption configuration.Defines each system partition encryption parameters.Show example(s) | |
