Constants

const ConfigTemplateAlphaV2 = `` /* 2352-byte string literal not displayed */

ConfigTemplateAlphaV2 is the kubadm config template for v1alpha2

NOTE: this is the v1.11 version of this API, breaking changes occurred in v1.12 vs v1.11, but v1.12 also has v1alpha3 which we use instead

see: https://github.com/kubernetes/kubernetes/tree/release-1.11/cmd/kubeadm/app/apis/kubeadm/v1alpha2

const ConfigTemplateAlphaV3 = `` /* 2771-byte string literal not displayed */

ConfigTemplateAlphaV3 is the kubadm config template for API version v1alpha3

const ConfigTemplateBetaV1 = `` /* 2774-byte string literal not displayed */

ConfigTemplateBetaV1 is the kubadm config template for API version v1beta1

const ConfigTemplateBetaV2 = `` /* 2773-byte string literal not displayed */

ConfigTemplateBetaV2 is the kubadm config template for API version v1beta2

const ObjectName = "config"

ObjectName is the name every generated object will have I.E. `metadata:\nname: config`

const Token = "abcdef.0123456789abcdef"

Token defines a dummy, well known token for automating TLS bootstrap process

Functions

func Config

func Config(data ConfigData) (config string, err error)

Config returns a kubeadm config generated from config data, in particular the kubernetes version

Types

type ConfigData

type ConfigData struct {
	ClusterName       string
	KubernetesVersion string
	// The ControlPlaneEndpoint, that is the address of the external loadbalancer
	// if defined or the bootstrap node
	ControlPlaneEndpoint string
	// The Local API Server port
	APIBindPort int
	// The API server external listen IP (which we will port forward)
	APIServerAddress string
	// ControlPlane flag specifies the node belongs to the control plane
	ControlPlane bool
	// The main IP address of the node
	NodeAddress string
	// The Token for TLS bootstrap
	Token string
	// The subnet used for pods
	PodSubnet string
	// The subnet used for services
	ServiceSubnet string
	// IPv4 values take precedence over IPv6 by default, if true set IPv6 default values
	IPv6 bool
	// DerivedConfigData is populated by Derive()
	// These auto-generated fields are available to Config templates,
	// but not meant to be set by hand
	DerivedConfigData
}

ConfigData is supplied to the kubeadm config template, with values populated by the cluster package

func (*ConfigData) Derive

func (c *ConfigData) Derive()

Derive automatically derives DockerStableTag if not specified

type DerivedConfigData

type DerivedConfigData struct {
	// DockerStableTag is automatically derived from KubernetesVersion
	DockerStableTag string
}

DerivedConfigData fields are automatically derived by ConfigData.Derive if they are not specified / zero valued
