Functions

func CreateSystemCgroups

func CreateSystemCgroups(ctx context.Context, log *zap.Logger, rt runtime.Runtime, next NextTaskFunc) error

CreateSystemCgroups creates system cgroups.

func InitVolumeLifecycle

func InitVolumeLifecycle(ctx context.Context, log *zap.Logger, rt runtime.Runtime, next NextTaskFunc) error

InitVolumeLifecycle initializes volume lifecycle resource.

func LogMode

func LogMode(ctx context.Context, log *zap.Logger, rt runtime.Runtime, next NextTaskFunc) error

LogMode prints the current mode.

func MountCgroups

func MountCgroups(ctx context.Context, log *zap.Logger, rt runtime.Runtime, next NextTaskFunc) error

MountCgroups represents mounts the cgroupfs (only in !container).

func MountPseudoLate

func MountPseudoLate(ctx context.Context, log *zap.Logger, rt runtime.Runtime, next NextTaskFunc) error

SetEnvironmentVariables sets the environment variables.

func SetRLimit

func SetRLimit(ctx context.Context, log *zap.Logger, rt runtime.Runtime, next NextTaskFunc) error

SetRLimit sets the file descriptor limit.

func SetupSystemDirectories

func SetupSystemDirectories(ctx context.Context, log *zap.Logger, rt runtime.Runtime, next NextTaskFunc) error

SetupSystemDirectories creates system default directories.

WriteIMAPolicy represents the WriteIMAPolicy task.

Types

type NextTaskFunc

type NextTaskFunc func() Task

NextTaskFunc is a function which returns the next task in the chain.

type Task

type Task func(context.Context, *zap.Logger, runtime.Runtime, NextTaskFunc) error

Task is a function that performs a startup task.

It is supposed to call the next task in the chain.

func DefaultTasks

func DefaultTasks() []Task

DefaultTasks returns the default startup tasks.
