示例1: upgradeCharm
// upgradeCharm upgrades the charm for the given service to the given charm id.
// If the service is already deployed using the given charm id, do nothing.
// This function returns an error if the existing charm and the target one are
// incompatible, meaning an upgrade from one to the other is not allowed.
func upgradeCharm(client *api.Client, log deploymentLogger, service, id string) error {
existing, err := client.ServiceGetCharmURL(service)
if err != nil {
return errors.Annotatef(err, "cannot retrieve info for service %q", service)
