示例1: UploadTools

// the environment storage, after which it sets the agent-version. If forceVersion is true,
// we allow uploading even when the agent-version is already set in the environment.
func UploadTools(ctx environs.BootstrapContext, env environs.Environ, toolsArch *string, forceVersion bool, bootstrapSeries ...string) error {
logger.Infof("checking that upload is possible")
// Check the series are valid.

if _, err := ubuntu.SeriesVersion(series); err != nil {
return err
}
}
// See that we are allowed to upload the tools.
if err := validateUploadAllowed(env, toolsArch, forceVersion); err != nil {
return err
}
// Make storage interruptible.
