Method normalizeNetMode

daemon/container_operations.go:938–952

normalizeNetMode checks whether the network mode references a network by a partial ID. In that case, it replaces the partial ID with the full network ID. TODO(aker): transform ID into name when the referenced network is one of the predefined.

(ctr *container.Container)

// partial ID with the full network ID.
// TODO(aker): transform ID into name when the referenced network is one of the predefined.
