Types

type CloudConfig 

type CloudConfig struct {
	SSHAuthorizedKeys []string `yaml:"ssh_authorized_keys"`
	Coreos            struct {
		Etcd   EtcdEnvironment
		Fleet  FleetEnvironment
		OEM    OEMRelease
		Update UpdateConfig
		Units  []system.Unit
	}
	WriteFiles        []system.File `yaml:"write_files"`
	Hostname          string
	Users             []system.User
	ManageEtcHosts    EtcHosts `yaml:"manage_etc_hosts"`
	NetworkConfigPath string
	NetworkConfig     string
}

CloudConfig encapsulates the entire cloud-config configuration file and maps directly to YAML

func NewCloudConfig 

func NewCloudConfig(contents string) (*CloudConfig, error)

NewCloudConfig instantiates a new CloudConfig from the given contents (a string of YAML), returning any error encountered. It will ignore unknown fields but log encountering them.

func ParseMetaData added in v0.8.0 

func ParseMetaData(contents string) (*CloudConfig, error)

ParseMetaData parses a JSON blob in the OpenStack metadata service format, and converts it to a partially hydrated CloudConfig.

func (CloudConfig) String

type CloudConfigFile added in v0.7.0 

type CloudConfigFile interface {
	// File should either return (*system.File, error), or (nil, nil) if nothing
	// needs to be done for this configuration option.
	File(root string) (*system.File, error)
}

CloudConfigFile represents a CoreOS specific configuration option that can generate an associated system.File to be written to disk

type CloudConfigUnit added in v0.7.0 

type CloudConfigUnit interface {
	Units(root string) ([]system.Unit, error)
}

CloudConfigUnit represents a CoreOS specific configuration option that can generate associated system.Units to be created/enabled appropriately

type Environment struct {
	// contains filtered or unexported fields
}

func NewEnvironment 

func NewEnvironment(root, configRoot, workspace, netconfType, sshKeyName string, substitutions map[string]string) *Environment
