示例1: MachineConfig
// MachineConfig returns information from the environment config that is
// needed for machine cloud-init (for non-state servers only).
// It is exposed for testing purposes.
// TODO(rog) fix environs/manual tests so they do not need to
// call this, or move this elsewhere.
func MachineConfig(st *state.State, machineId, nonce, dataDir string) (*cloudinit.MachineConfig, error) {
environConfig, err := st.EnvironConfig()
if err != nil {
return nil, err
}
// Get the machine so we can get its series and arch.
// If the Arch is not set in hardware-characteristics,
// an error is returned.
machine, err := st.Machine(machineId)
if err != nil {
return nil, err
}
hc, err := machine.HardwareCharacteristics()
if err != nil {
return nil, err
}
if hc.Arch == nil {
return nil, fmt.Errorf("arch is not set for %q", machine.Tag())
}
// Find the appropriate tools information.
env, err := environs.New(environConfig)
if err != nil {
return nil, err
}
tools, err := findInstanceTools(env, machine.Series(), *hc.Arch)
if err != nil {
