Types

type Bootstrapper

type Bootstrapper interface {
	Script() (string, error)
}

Bootstrapper can be implemented to generate a bootstrap script that uses the params from the Bootstrap type for a specific bootstrapping method. Examples are the Bottlerocket config and the eks-bootstrap script

type Bottlerocket

type Bottlerocket struct {
	Options
}

func (Bottlerocket) Script

func (b Bottlerocket) Script() (string, error)

type BottlerocketConfig

type BottlerocketConfig struct {
	SettingsRaw map[string]interface{} `toml:"settings"`
	Settings    BottlerocketSettings   `toml:"-"`
}

BottlerocketConfig is the root of the bottlerocket config, see more here https://github.com/bottlerocket-os/bottlerocket#using-user-data

func NewBottlerocketConfig

func NewBottlerocketConfig(userdata *string) (*BottlerocketConfig, error)

func (*BottlerocketConfig) MarshalTOML
