var RunningInUserNS = runningInUserNS

RunningInUserNS detects whether we are currently running in a user namespace.

Functions

func GetUserNamespaceMappings 

func GetUserNamespaceMappings(nsPath string) (uidMap, gidMap []configs.IDMap, err error)

func IsSameMapping 

func IsSameMapping(a, b []configs.IDMap) bool

IsSameMapping returns whether or not the two id mappings are the same. Note that if the order of the mappings is different, or a mapping has been split, the mappings will be considered different.

Types

type Handles 

type Handles struct {
	// contains filtered or unexported fields
}

func (*Handles) Get 

func (hs *Handles) Get(req Mapping) (file *os.File, err error)

Get returns a handle to a /proc/$pid/ns/user nsfs file with the requested mapping. The processes spawned to produce userns nsfds are cached, so if equivalent user namespace mappings are requested, the same user namespace will be returned. The caller is responsible for closing the returned file descriptor.

func (*Handles) Release 

func (hs *Handles) Release()

Release all resources associated with this Handle. All existing files returned from Get() will continue to work even after calling Release(). The same Handles can be re-used after calling Release().

type Mapping 

type Mapping struct {
	UIDMappings []configs.IDMap
	GIDMappings []configs.IDMap
}
