Functions

func AddNamespaceRangesUser

func AddNamespaceRangesUser(name string) (int, int, error)

AddNamespaceRangesUser takes a username and uses the standard system utility to create a system user/group pair used to hold the /etc/sub{uid,gid} ranges which will be used for user namespace mapping ranges in containers.

func LoadIdentityMapping

func LoadIdentityMapping(name string) (idtools.IdentityMapping, error)

LoadIdentityMapping takes a requested username and using the data from /etc/sub{uid,gid} ranges, creates the proper uid and gid remapping ranges for that user/group pair

func LookupGID

func LookupGID(gid int) (user.Group, error)

LookupGID uses traditional local system files lookup (from libcontainer/user) on a group ID, followed by a call to `getent` for supporting host configured non-files passwd and group dbs

func LookupGroup

func LookupGroup(name string) (user.Group, error)

LookupGroup uses traditional local system files lookup (from libcontainer/user) on a group name, followed by a call to `getent` for supporting host configured non-files passwd and group dbs

func LookupUID

func LookupUID(uid int) (user.User, error)

LookupUID uses traditional local system files lookup (from libcontainer/user) on a uid, followed by a call to `getent` for supporting host configured non-files passwd and group dbs

func LookupUser

func LookupUser(name string) (user.User, error)

LookupUser uses traditional local system files lookup (from libcontainer/user) on a username, followed by a call to `getent` for supporting host configured non-files passwd and group dbs
