Functions

func GetBootcmdline

func GetBootcmdline() (string, error)

func InitializeStatusConditions

func InitializeStatusConditions() []tunedv1.ProfileStatusCondition

InitializeStatusConditions returns a slice of tunedv1.ProfileStatusCondition initialized to an unknown state.

func PrepareOpenShiftTunedDir

func PrepareOpenShiftTunedDir() error

func RunInCluster

func RunInCluster(stopCh <-chan struct{}, version string) error

func RunOutOfClusterOneShot

func RunOutOfClusterOneShot(stopCh <-chan struct{}, version string) error

func TunedCreateCmdline

func TunedCreateCmdline(debug bool) (string, []string)

func TunedRecommendFileRead

func TunedRecommendFileRead() (string, error)

func TunedRecommendFileReadPath

func TunedRecommendFileReadPath(recommendFilePath string) (string, error)

func TunedRecommendFileWrite

func TunedRecommendFileWrite(profileName string) error

func TunedRecommendFileWritePath

func TunedRecommendFileWritePath(recommendFilePath, profileName string) error

func TunedRsyncEtc

func TunedRsyncEtc() error

TunedRsyncEtcToHost propagates the changes from container's read-only TuneD /etc/tuned.orig directory to the container's Memory-backed read-write TuneD /etc/tuned directory. This function only serves the purpose to enable readOnlyRootFilesystem for the NTO operand.

func TunedRun
