type UnitFile added in v0.7.0

type UnitFile struct {
	// Contents represents the parsed unit file.
	// This field must be considered readonly.
	Contents map[string]map[string][]string

	Options []*unit.UnitOption

A UnitFile represents a systemd configuration which encodes information about any of the unit types that fleet supports (as defined in SupportedUnitTypes()). UnitFiles are linked to Units by the Hash of their contents. Similar to systemd, a UnitFile configuration has no inherent name, but is rather named through the reference to it; in the case of systemd, the reference is the filename, and in the case of fleet, the reference is the name of the Unit that references this UnitFile.

func (u *UnitFile) Hash() Hash

Hash returns the SHA1 hash of the raw contents of the Unit

func (*UnitFile) String added in v0.7.0

func (u *UnitFile) String() string

func (*UnitFile) ToPB added in v1.0.0

func (unitFile *UnitFile) ToPB() pb.UnitFile

type UnitManager added in v0.4.0

type UnitManager interface {
	Load(string, UnitFile) error
	Unload(string) error
	ReloadUnitFiles() error

	TriggerStart(string) error
	TriggerStop(string) error

	Units() ([]string, error)
	GetUnitStates(pkg.Set) (map[string]*UnitState, error)
	GetUnitState(string) (*UnitState, error)

type UnitNameInfo added in v0.5.0

type UnitNameInfo struct {
	FullName string // Original complete name of the unit (e.g. foo.socket, foo@bar.service)
	Name     string // Name of the unit without suffix (e.g. foo, foo@bar)
	Prefix   string // Prefix of the template unit (e.g. foo)

	// If the unit represents an instance or a template, the following values are set
	Template string // Name of the canonical template unit (e.g. foo@.service)
	Instance string // Instance name (e.g. bar)

UnitNameInfo exposes certain interesting items about a Unit based on its name. For example, a unit with the name "foo@.service" constitutes a template unit, and a unit named "foo@1.service" would represent an instance unit of that template.

func NewUnitNameInfo added in v0.5.0

func NewUnitNameInfo(un string) *UnitNameInfo

NewUnitNameInfo generates a UnitNameInfo from the given name. If the given string is not a correct unit name, nil is returned.
