Constants ¶
const ( // 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. NonceFile = "nonce.txt" )
const UserDataScript = `` /* 1515-byte string literal not displayed */
Variables ¶
var ( // UbuntuGroups is the set of unix groups to add the "ubuntu" user to // when initializing an Ubuntu system. UbuntuGroups = []string{"adm", "audio", "cdrom", "dialout", "dip", "floppy", "netdev", "plugdev", "sudo", "video"} // CentOSGroups is the set of unix groups to add the "ubuntu" user to // when initializing a CentOS system.

MachineCloudInitDir is for testing purposes.
Functions ¶
func CloudConfigByVersionFunc ¶
func CloudConfigByVersionFunc(series string) cloudConfigTranslateFunc
CloudConfigByVersionFunc returns the correct function to translate container-inherit-properties to cloud-init data based on series.
func GetMachineCloudInitData ¶
GetMachineCloudInitData returns a map of all cloud init data on the machine.
func SetUbuntuUser ¶
func SetUbuntuUser(conf cloudinit.CloudConfig, authorizedKeys string)
SetUbuntuUser creates an "ubuntu" use for unix systems so the juju client can access the machine using ssh with the configuration we expect. On precise, the default cloudinit version is too old to support the users option, so instead rely on the default user being created and adding keys. It may make sense in the future to add a "juju" user instead across all distributions.
Types ¶
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
// ConfigureCustomOverrides updates the provided cloudinit.Config with
// user provided cloudinit data. Data provided will overwrite current
// values with three exceptions: preruncmd was handled in ConfigureBasic()
// and packages and postruncmd were handled in ConfigureJuju().
ConfigureCustomOverrides() error
}
UserdataConfig is the bridge between instancecfg and cloudinit It supports different levels of configuration for instances
func NewUserdataConfig ¶
func NewUserdataConfig(icfg *instancecfg.InstanceConfig, conf cloudinit.CloudConfig) (UserdataConfig, error)
NewUserdataConfig is supposed to take in an instanceConfig as well as a cloudinit.cloudConfig and add attributes in the cloudinit structure based on the values inside instanceConfig and on the series
