	// ClusterToken is a unique string that can be used to distinguish different clusters on networks with multiple clusters.
	ClusterToken string `yaml:"cluster_token,omitempty" json:"cluster_token,omitempty"`

	// ControlPlaneHost is a host that all nodes can resolve and use for node registration.

	// Role informs the sdk what kind of installation to manage on this device.
	Role Role `yaml:"role,omitempty" json:"role,omitempty"`

	// Options are arbitrary values the sdk may be interested in.  These values are not validated by Kairos and are simply forwarded to the sdk.

}

type ClusterPlugin

type ClusterPlugin struct {
	Provider ClusterProvider
}

ClusterPlugin creates a cluster plugin from a `ClusterProvider`. It calls the cluster provider at the appropriate events and ensures it configuration is written where it will be executed.

func (ClusterPlugin) Run

func (p ClusterPlugin) Run() error

type ClusterProvider

type ClusterProvider func(cluster Cluster) yip.YipConfig

ClusterProvider returns a yip configuration that configures a Kubernetes engine. The yip config may use any elemental stages after initramfs.

type Config

type Config struct {
	Cluster *Cluster `yaml:"cluster,omitempty" json:"cluster,omitempty"`
}

type Role

type Role string

func (*Role) MarshalJSON

func (n *Role) MarshalJSON() ([]byte, error)

func (*Role) MarshalYAML

func (n *Role) MarshalYAML() (interface{}, error)

func (*Role) UnmarshalJSON

func (n *Role) UnmarshalJSON(val []byte) error

func (*Role) UnmarshalYAML

func (n *Role) UnmarshalYAML(unmarshal func(interface{}) error) error
