Functions

func FetchAndCheckSnapAssertions

func FetchAndCheckSnapAssertions(snapPath string, info *snap.Info, model *asserts.Model, f asserts.Fetcher, db asserts.RODatabase) (*asserts.SnapDeclaration, error)

FetchAndCheckSnapAssertions fetches and cross checks the snap assertions matching the given snap file using the provided asserts.Fetcher and assertion database. The optional model assertion must be passed for full cross checks.

func MockTrusted

func MockTrusted(mockTrusted []asserts.Assertion) (restore func())

func Prepare

func Prepare(opts *Options) error

Types

type Customizations

type Customizations struct {
	// ConsoleConf can be set to "disabled" to disable console-conf
	// forcefully (UC16/18 only ATM).
	ConsoleConf string `json:"console-conf"`
	// CloudInitUserData can optionally point to cloud init user-data
	// (UC16/18 only)
	CloudInitUserData string `json:"cloud-init-user-data"`
	// BootFlags can be set to a list of boot flags
	// to set in the recovery bootloader (UC20 only).
	// Currently only the "factory" hint flag is supported.
	BootFlags []string `json:"boot-flags"`
	// Validation controls whether validations should be taken
	// into account by the store to select snap revisions.
	// It can be set to "enforce" or "ignore".
	Validation string `json:"validation"`
}

Customizatons defines possible image customizations. Not all of them applies to all kind of systems.
