// namespace configuration linkage to the libnetwork "sandbox" entity
func (container *Container) setNetworkNamespaceKey(pid int) error {
	path := fmt.Sprintf("/proc/%d/ns/net", pid)
	var sandbox libnetwork.Sandbox
	search := libnetwork.SandboxContainerWalker(&sandbox, container.ID)
	container.daemon.netController.WalkSandboxes(search)
	if sandbox == nil {
		return fmt.Errorf("no sandbox present for %s", container.ID)
	}

	return sandbox.SetKey(path)
}
