Types

type NetNS

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

NetNS holds network namespace.

func LoadNetNS

func LoadNetNS(path string) *NetNS

LoadNetNS loads existing network namespace.

func NewNetNS

func NewNetNS(baseDir, name string) (*NetNS, error)

NewNetNS creates a network namespace. The name of the network namespace is randomly generated. The returned netns is created under baseDir, with its path following the pattern "baseDir/<generated-name>".

func NewNetNSFromPID

func NewNetNSFromPID(baseDir, name string, pid uint32) (*NetNS, error)

NewNetNSFromPID returns the netns from pid or a new netns if pid is 0. The name of the network namespace is randomly generated. The returned netns is created under baseDir, with its path following the pattern "baseDir/<generated-name>".

func (*NetNS) Closed

func (n *NetNS) Closed() (bool, error)

Closed checks whether the network namespace has been closed.

func (*NetNS) Do

func (n *NetNS) Do(f func(cnins.NetNS) error) error

Do runs a function in the network namespace.

func (*NetNS) GetPath

func (n *NetNS) GetPath() string

GetPath returns network namespace path for sandbox container

func (*NetNS) Remove

func (n *NetNS) Remove() error

Remove removes network namespace. Remove is idempotent, meaning it might be invoked multiple times and provides consistent result.
