Point-to-Point Plugin

The PTP plugin allows a virtual device that is attached to a virtual interface in the host to be created in the container.

The following options are used to configure the plugin:

name (string, required)

The name of the network.

type (string, required)

ptp

ipMasq (boolean, optional)

Set up IP Masquerade on the host for traffic originating from the IP address of this network and destined outside of this network. Default: false.

mtu (integer, optional)

Set the MTU to the specified value. Default: chosen by the kernel.

ipam (dictionary, required)

The IPAM configuration to be used for this network. For an interface without an IP address, use an empty dictionary.

Example

The following example creates a pod containing an additional network interface corresponding to a point-to-point interface.

apiVersion: "k8s.cni.cncf.io/v1"

  name: ptp0

  config: '{

              }
          ]
