Errors related to systemd.

Functions

func Configure

func Configure(vl func(f string, v ...interface{}))

Configure sets the logger for this package.

func IsJobDependency

func IsJobDependency(err error) bool

IsJobDependency returns true if the given err is a JobDependencyError.

Types

type SystemdClient

type SystemdClient struct{}

SystemdClient is a client for managing systemd.

func NewSystemdClient

func NewSystemdClient() (*SystemdClient, error)

NewSystemdClient returns a new SystemdClient.

func (*SystemdClient) Exists

func (sdc *SystemdClient) Exists(unit string) (bool, error)

Exists checks if a unit exists in systemd.

func (*SystemdClient) Reload

func (sdc *SystemdClient) Reload() error

Reload instructs systemd to scan for and reload unit files. Equivalent to a 'systemctl daemon-reload'. See https://godoc.org/github.com/coreos/go-systemd/dbus#Conn.Reload.

func (*SystemdClient) Start

func (sdc *SystemdClient) Start(unit string) error

Start instructs systemd to start a job. See http://godoc.org/github.com/coreos/go-systemd/dbus#Conn.StartUnit.

func (*SystemdClient) Stop

func (sdc *SystemdClient) Stop(unit string) error

Stop instructs systemd to stop a job. See https://godoc.org/github.com/coreos/go-systemd/dbus#Conn.StopUnit.
