const NonceFile = "nonce.txt"

NonceFile is written by cloud-init as the last thing it does. The file will contain the machine's nonce. The filename is relative to the Juju data-dir.

Functions

func AddAptCommands

func AddAptCommands(
	proxySettings proxy.Settings,
	aptMirror string,
	c *cloudinit.Config,
	addUpdateScripts bool,
	addUpgradeScripts bool,
)

AddAptCommands update the cloudinit.Config instance with the necessary packages, the request to do the apt-get update/upgrade on boot, and adds the apt proxy and mirror settings if there are any.

func MaybeAddCloudArchiveCloudTools

func MaybeAddCloudArchiveCloudTools(c *cloudinit.Config, series string)

MaybeAddCloudArchiveCloudTools adds the cloud-archive cloud-tools pocket to apt sources, if the series requires it.

Types

type MachineConfig

type MachineConfig struct {
	// Bootstrap specifies whether the new machine is the bootstrap
	// machine. When this is true, StateServingInfo should be set
	// and filled out.
	Bootstrap bool

	// StateServingInfo holds the information for serving the state.
	// This must only be set if the Bootstrap field is true
	// (state servers started subsequently will acquire their serving info
	// from another server)
	StateServingInfo *params.StateServingInfo

	// MongoInfo holds the means for the new instance to communicate with the
	// juju state database. Unless the new machine is running a state server
	// (StateServer is set), there must be at least one state server address supplied.
	// The entity name must match that of the machine being started,
	// or be empty when starting a state server.
	MongoInfo *mongo.MongoInfo

	// APIInfo holds the means for the new instance to communicate with the
	// juju state API. Unless the new machine is running a state server (StateServer is
	// set), there must be at least one state server address supplied.
	// The entity name must match that of the machine being started,
	// or be empty when starting a state server.
	APIInfo *api.Info

	// InstanceId is the instance ID of the machine being initialised.
	// This is required when bootstrapping, and ignored otherwise.
	InstanceId instance.Id

	// HardwareCharacteristics contains the harrdware characteristics of
	// the machine being initialised. This optional, and is only used by
	// the bootstrap agent during state initialisation.
	HardwareCharacteristics *instance.HardwareCharacteristics

	// MachineNonce is set at provisioning/bootstrap time and used to
	// ensure the agent is running on the correct instance.
	MachineNonce string

	// Tools is juju tools to be used on the new machine.
	Tools *coretools.Tools

	// DataDir holds the directory that juju state will be put in the new
	// machine.
	DataDir string

	// LogDir holds the directory that juju logs will be written to.
	LogDir string

	// Jobs holds what machine jobs to run.
	Jobs []multiwatcher.MachineJob

	// CloudInitOutputLog specifies the path to the output log for cloud-init.
	// The directory containing the log file must already exist.
	CloudInitOutputLog string

	// MachineId identifies the new machine.
	MachineId string

	// MachineContainerType specifies the type of container that the machine
	// is.  If the machine is not a container, then the type is "".
	MachineContainerType instance.ContainerType

	// Networks holds a list of networks the machine should be on.
	Networks []string

	// AuthorizedKeys specifies the keys that are allowed to
	// connect to the machine (see cloudinit.SSHAddAuthorizedKeys)
	// If no keys are supplied, there can be no ssh access to the node.
	// On a bootstrap machine, that is fatal. On other
	// machines it will mean that the ssh, scp and debug-hooks
	// commands cannot work.
	AuthorizedKeys string

	// AgentEnvironment defines additional configuration variables to set in
	// the machine agent config.
	AgentEnvironment map[string]string

	// WARNING: this is only set if the machine being configured is
	// a state server node.
	//
	// Config holds the initial environment configuration.
	Config *config.Config

	// Constraints holds the initial environment constraints.
	Constraints constraints.Value

	// DisableSSLHostnameVerification can be set to true to tell cloud-init
	// that it shouldn't verify SSL certificates
	DisableSSLHostnameVerification bool

	// Series represents the machine series.
	Series string

	// MachineAgentServiceName is the init service name for the Juju machine agent.
	MachineAgentServiceName string

	// ProxySettings define normal http, https and ftp proxies.
	ProxySettings proxy.Settings

	// AptProxySettings define the http, https and ftp proxy settings to use
	// for apt, which may or may not be the same as the normal ProxySettings.
	AptProxySettings proxy.Settings

	// AptMirror defines an APT mirror location, which, if specified, will
	// override the default APT sources.
	AptMirror string

	// PreferIPv6 mirrors the value of prefer-ipv6 environment setting
	// and when set IPv6 addresses for connecting to the API/state
	// servers will be preferred over IPv4 ones.
	PreferIPv6 bool

	// The type of Simple Stream to download and deploy on this machine.
	ImageStream string

	// CustomImageMetadata is optional custom simplestreams image metadata
	// to store in environment storage at bootstrap time. This is ignored
	// in non-bootstrap machines.
	CustomImageMetadata []*imagemetadata.ImageMetadata

	// EnableOSRefreshUpdate specifies whether Juju will refresh its
	// respective OS's updates list.
	EnableOSRefreshUpdate bool

	// EnableOSUpgrade defines Juju's behavior when provisioning
	// machines. If enabled, the OS will perform any upgrades
	// available as part of its provisioning.
	EnableOSUpgrade bool
}

MachineConfig represents initialization information for a new juju machine.

func (*MachineConfig) HasNetworks

func (cfg *MachineConfig) HasNetworks() bool

HasNetworks returns if there are any networks set.

type UserdataConfig

type UserdataConfig interface {
	// Configure is a convenience function that updates the cloudinit.Config
	// with appropriate configuration. It will run ConfigureBasic() and
	// ConfigureJuju()
	Configure() error
	// ConfigureBasic updates the provided cloudinit.Config with
	// basic configuration to initialise an OS image.
	ConfigureBasic() error
	// ConfigureJuju updates the provided cloudinit.Config with configuration
	// to initialise a Juju machine agent.
	ConfigureJuju() error
	// Render renders the cloudinit/cloudbase-init userdata needed to initialize
	// the juju agent
	Render() ([]byte, error)
}

func NewUserdataConfig

func NewUserdataConfig(cfg *MachineConfig, c *cloudinit.Config) (UserdataConfig, error)
