func (*T) AllocatableRange ¶

func (t *T) AllocatableRange(_ string) (*net.IPNet, error)

AllocatableRange returns the whole subnet of the network.

A bridge network is node local and its addresses are not routable: the bridge is per node, nothing carries the subnet between nodes, and the same address on two nodes never meets. So every node draws from all of it, and the slicing a routed_bridge needs would only make the range smaller for no gain.

func (*T) BackendDevName ¶

func (t *T) BackendDevName() string

func (*T) CNIConfigData ¶

func (t *T) CNIConfigData() (interface{}, error)

CNIConfigData returns a cni network configuration, like

{
  "bridge": "cni0",
  "cniVersion": "0.3.0",
  "ipMasq": false,
  "name": "mynet",
  "ipam": {
    "routes": [
      {"dst": "0.0.0.0/0"}
    ],
    "subnet": "10.22.0.0/16",
    "type": "host-local"
  },
  "isGateway": true,
  "type": "bridge"
}

func (*T) IsIP6 ¶

func (t *T) IsIP6() bool

func (*T) Setup ¶

func (t *T) Setup() error
