Functions

func GetBootKernelConfigMap

func GetBootKernelConfigMap(bootDir, kernelVersion string) (configMap map[string]string, err error)

GetBootKernelConfigMap reads the kernel config into a key-value map. It tries to read kernel config from ${bootDir}/config-${kernelVersion}, and comments are ignored. If the bootDir is empty, it points to /boot by default.

func GetKernelRelease

func GetKernelRelease() (string, error)

GetKernelRelease returns the kernel release string.

func GetOSDistro

func GetOSDistro(osReleaseContent string) (string, error)

GetOSDistro reads the /etc/os-release file and returns the ID field.

func GetProcKernelConfigMap

func GetProcKernelConfigMap(procDir string) (configMap map[string]string, err error)

GetProcKernelConfigMap reads the kernel config into a key-value map. It tries to read kernel config from procfs mounted at procDir from the view of processName in namespace. If the procDir is empty, it points to /proc by default.

func GetSystemBlockDeviceInfo

func GetSystemBlockDeviceInfo() (map[string]types.BlockDeviceInfo, error)

GetSystemBlockDeviceInfo returns the block device info for the system.
