func ReplaceNetNSWithName ¶

func ReplaceNetNSWithName(netNSName string) (ns.NetNS, error)

ReplaceNetNSWithName creates a network namespace with the given name and returns a handle to it. If such netns already exists from a previous run, it will be removed and then re-created to avoid any previous state of the netns.

Example usage of this function:

netns0, err := netns.ReplaceNetNSWithName(netnsName)
if err != nil {
  return err
}
defer netns.RemoveNetNSWithName(netnsName)

netns0.Do(func(_ ns.NetNS) error {
  <logic to be executed within the new netns>
})
