Types

type ModelConfigCreator

type ModelConfigCreator struct {
	// Provider will be used to obtain EnvironProviders for preparing
	// and validating configuration.
	Provider func(string) (environs.EnvironProvider, error)

	// FindTools, if non-nil, will be used to validate the agent-version
	// value in NewModelConfig if it differs from the base configuration.
	//
	// If FindTools is nil, agent-version may not be different to the
	// base configuration.
	FindTools func(version.Number) (tools.List, error)
}

ModelConfigCreator provides a method of creating a new model config.

The zero value of ModelConfigCreator is usable with the limitations noted on each struct field.

func (ModelConfigCreator) NewModelConfig

func (c ModelConfigCreator) NewModelConfig(
	cloud environscloudspec.CloudSpec,
	base *config.Config,
	attrs map[string]interface{},
) (*config.Config, error)

NewModelConfig returns a new model config given a base (controller) config and a set of attributes that will be specific to the new model, overriding any non-restricted attributes in the base configuration. The resulting config will be suitable for creating a new model in state.

If "attrs" does not include a UUID, a new, random one will be generated and added to the config.

The config will be validated with the provider before being returned.
