Types ¶

type InitSystem ¶

type InitSystem interface {
	// return a string describing how to enable a service
	EnableCommand(service string) string

	// ServiceStart tries to start a specific service
	ServiceStart(service string) error

	// ServiceStop tries to stop a specific service
	ServiceStop(service string) error

	// ServiceRestart tries to reload the environment and restart the specific service
	ServiceRestart(service string) error

	// ServiceExists ensures the service is defined for this init system.
	ServiceExists(service string) bool

	// ServiceIsEnabled ensures the service is enabled to start on each boot.
	ServiceIsEnabled(service string) bool

	// ServiceIsActive ensures the service is running, or attempting to run. (crash looping in the case of kubelet)
	ServiceIsActive(service string) bool
}

func GetInitSystem ¶

func GetInitSystem() (InitSystem, error)

GetInitSystem returns an InitSystem for the current system, or nil if we cannot detect a supported init system for pre-flight checks. This indicates we will skip init system checks, not an error.

type OpenRCInitSystem ¶

type OpenRCInitSystem struct{}

func (OpenRCInitSystem) EnableCommand ¶

func (openrc OpenRCInitSystem) EnableCommand(service string) string

func (OpenRCInitSystem) ServiceExists ¶

func (openrc OpenRCInitSystem) ServiceExists(service string) bool

openrc writes to stderr if a service is not found or not enabled this is in contrast to systemd which only writes to stdout. Hence, we use the Combinedoutput, and ignore the error.

func (OpenRCInitSystem) ServiceIsActive ¶

func (openrc OpenRCInitSystem) ServiceIsActive(service string) bool

func (OpenRCInitSystem) ServiceIsEnabled ¶

func (openrc OpenRCInitSystem) ServiceIsEnabled(service string) bool

func (OpenRCInitSystem) ServiceRestart ¶

func (openrc OpenRCInitSystem) ServiceRestart(service string) error

func (OpenRCInitSystem) ServiceStart ¶

func (openrc OpenRCInitSystem) ServiceStart(service string) error

func (OpenRCInitSystem) ServiceStop ¶

func (openrc OpenRCInitSystem) ServiceStop(service string) error

type SystemdInitSystem ¶

type SystemdInitSystem struct{}

func (SystemdInitSystem) EnableCommand ¶

func (sysd SystemdInitSystem) EnableCommand(service string) string

func (SystemdInitSystem) ServiceExists ¶

func (sysd SystemdInitSystem) ServiceExists(service string) bool

func (SystemdInitSystem) ServiceIsActive ¶

func (sysd SystemdInitSystem) ServiceIsActive(service string) bool

ServiceIsActive will check is the service is "active". In the case of crash looping services (kubelet in our case) status will return as "activating", so we will consider this active as well.

func (SystemdInitSystem) ServiceIsEnabled ¶

func (sysd SystemdInitSystem) ServiceIsEnabled(service string) bool

func (SystemdInitSystem) ServiceRestart ¶

func (sysd SystemdInitSystem) ServiceRestart(service string) error

func (SystemdInitSystem) ServiceStart ¶

func (sysd SystemdInitSystem) ServiceStart(service string) error

func (SystemdInitSystem) ServiceStop ¶

func (sysd SystemdInitSystem) ServiceStop(service string) error

type WindowsInitSystem ¶

type WindowsInitSystem struct{}

WindowsInitSystem is the windows implementation of InitSystem

func (WindowsInitSystem) EnableCommand ¶

func (sysd WindowsInitSystem) EnableCommand(service string) string

func (WindowsInitSystem) ServiceExists ¶

func (sysd WindowsInitSystem) ServiceExists(service string) bool

func (WindowsInitSystem) ServiceIsActive ¶

func (sysd WindowsInitSystem) ServiceIsActive(service string) bool

func (WindowsInitSystem) ServiceIsEnabled ¶

func (sysd WindowsInitSystem) ServiceIsEnabled(service string) bool

func (WindowsInitSystem) ServiceRestart ¶

func (sysd WindowsInitSystem) ServiceRestart(service string) error

func (WindowsInitSystem) ServiceStart ¶

func (sysd WindowsInitSystem) ServiceStart(service string) error

func (WindowsInitSystem) ServiceStop ¶

func (sysd WindowsInitSystem) ServiceStop(service string) error
