Constants ¶
const ( LibSystemdDir = "/lib/systemd/system" EtcSystemdDir = "/etc/systemd/system" EtcSystemdMultiUserDir = EtcSystemdDir + "/multi-user.target.wants" )
const CleanShutdownService = `` /* 236-byte string literal not displayed */
CleanShutdownService is added to machines to ensure DHCP-assigned IP addresses are released on shutdown, reboot, or halt. See bug http://pad.lv/1348663 for more info.
const CleanShutdownServicePath = "/etc/systemd/system/juju-clean-shutdown.service"
CleanShutdownServicePath is the full file path where CleanShutdownService is created.
Variables ¶
var NewDBusAPI = func() (DBusAPI, error) { return dbus.New() }
Functions ¶
func IsRunning ¶
func IsRunning() bool
IsRunning returns whether or not systemd is the local init system.
func ListCommand ¶
func ListCommand() string
ListCommand returns a command that will list the services on a host.
func ListServices ¶
ListServices returns the list of installed service names.
func UnitSerialize ¶
func UnitSerialize(opts []*unit.UnitOption) io.Reader
UnitSerialize encodes all of the given UnitOption objects into a unit file. Renamed from Serialize from github.com/coreos/go-systemd/unit so as to not conflict with the exported internal function in export_test.go.
Types ¶
type Cmdline ¶
type Cmdline struct {
// contains filtered or unexported fields
}
Cmdline exposes the core operations of interacting with systemd units.
type DBusAPI ¶
type DBusAPI interface {
Close()
ListUnits() ([]dbus.UnitStatus, error)
StartUnit(string, string, chan<- string) (int, error)
StopUnit(string, string, chan<- string) (int, error)
LinkUnitFiles([]string, bool, bool) ([]dbus.LinkUnitFileChange, error)
EnableUnitFiles([]string, bool, bool) (bool, []dbus.EnableUnitFileChange, error)
DisableUnitFiles([]string, bool) ([]dbus.DisableUnitFileChange, error)
GetUnitProperties(string) (map[string]interface{}, error)
GetUnitTypeProperties(string, string) (map[string]interface{}, error)
Reload() error
}
DBusAPI exposes all the systemd API methods needed by juju. To regenerate the mock for this interface, run "go generate" from the package directory.
type DBusAPIFactory ¶
Type alias for a DBusAPI factory method.
type Service ¶
type Service struct {
common.Service
ConfName string
UnitName string
DirName string
FallBackDirName string
Script []byte
// contains filtered or unexported fields
}
Service provides visibility into and control over a systemd service.
func NewService ¶
func NewService( name string, conf common.Conf, dataDir string, newDBus DBusAPIFactory, fallBackDirName string, ) (*Service, error)
NewService returns a new reference to an object that implements the Service interface for systemd.
func NewServiceWithDefaults ¶
NewServiceWithDefaults returns a new systemd service reference populated with sensible defaults.
func (*Service) InstallCommands ¶
InstallCommands implements Service.
func (*Service) StartCommands ¶
StartCommands implements Service.
func (*Service) WriteService ¶
WriteService implements UpgradableService.WriteService
