示例1: ConfigureBootstrapMachine
// ConfigureBootstrapMachine adds the initial machine into state. As a part
// of this process the environmental constraints are saved as constraints used
// when bootstrapping are considered constraints for the entire environment.
func ConfigureBootstrapMachine(
st *state.State,
cons constraints.Value,
datadir string,
jobs []state.MachineJob,
instId instance.Id,
characteristics instance.HardwareCharacteristics,
) error {
logger.Debugf("setting environment constraints")
if err := st.SetEnvironConstraints(cons); err != nil {
return err
}
logger.Debugf("create bootstrap machine in state")
m, err := st.InjectMachine(version.Current.Series, cons, instId, characteristics, jobs...)
if err != nil {
return err
}
// Read the machine agent's password and change it to
// a new password (other agents will change their password
// via the API connection).
