示例1: StateInfo

// StateInfo is a reusable implementation of Environ.StateInfo, available to
// providers that also use the other functionality from this file.
func StateInfo(env environs.Environ) (*state.Info, *api.Info, error) {
	st, err := bootstrap.LoadState(env.Storage())
	if err != nil {
		return nil, nil, err
	}
	config := env.Config()
	if _, hasCert := config.CACert(); !hasCert {
		return nil, nil, fmt.Errorf("no CA certificate in environment configuration")
	}
	// Wait for the addresses of at least one of the instances to become available.
	logger.Debugf("waiting for addresses of state server instances %v", st.StateInstances)
	var addresses []string
	for a := LongAttempt.Start(); len(addresses) == 0 && a.Next(); {
		insts, err := env.Instances(st.StateInstances)
		if err != nil && err != environs.ErrPartialInstances {
			logger.Debugf("error getting state instances: %v", err.Error())
			return nil, nil, err
		}
		addresses = getAddresses(insts)
	}

	if len(addresses) == 0 {
		return nil, nil, fmt.Errorf("timed out waiting for addresses from %v", st.StateInstances)
	}

	stateInfo, apiInfo := getStateInfo(config, addresses)
	return stateInfo, apiInfo, nil
}

示例2: assertEnvironDestroyed

func assertEnvironDestroyed(c *gc.C, env environs.Environ, store configstore.Storage) {
	_, err := store.ReadInfo(env.Config().Name())
	c.Assert(err, jc.Satisfies, errors.IsNotFound)

	_, err = env.Instances([]instance.Id{"invalid"})
	c.Assert(err, gc.ErrorMatches, "environment has been destroyed")
}

示例3: WaitInstanceAddresses

// WaitAddresses waits until the specified instance has addresses, and returns them.
func WaitInstanceAddresses(env environs.Environ, instId instance.Id) ([]network.Address, error) {
	for a := testing.LongAttempt.Start(); a.Next(); {
		insts, err := env.Instances([]instance.Id{instId})
		if err != nil {
			return nil, err
		}
		addresses, err := insts[0].Addresses()
		if err != nil {
			return nil, err
		}
		if len(addresses) > 0 {
			return addresses, nil
		}
	}
	return nil, errors.Errorf("timed out trying to get addresses for %v", instId)
}
