Functions

func GetAllBinaryProcs added in v0.11.0

func GetAllBinaryProcs() (map[string][]uint32, error)

GetProcNS returns the namespace ID of a given namespace and process. To do so, it requires access to the /proc file system of the host, and CAP_SYS_PTRACE capability.

func GetMountNSFirstProcesses

func GetMountNSFirstProcesses() (map[int]int, error)

GetMountNSFirstProcesses return mapping between mount NS to its first process (aka, the process with the oldest start time in the mount NS)

func GetProcBinary added in v0.11.0

func GetProcBinary(pid uint) (string, error)

GetProcNS returns the namespace ID of a given namespace and process. To do so, it requires access to the /proc file system of the host, and CAP_SYS_PTRACE capability.

func GetProcNS

func GetProcNS(pid uint, nsName string) (int, error)

GetProcNS returns the namespace ID of a given namespace and process. To do so, it requires access to the /proc file system of the host, and CAP_SYS_PTRACE capability.

func GetProcessStartTime

func GetProcessStartTime(pid uint) (int, error)

GetProcessStartTime return the start time of the process using the procfs
