Overview
dummy is a useful feature for routing packets through the Linux kernel without transmitting.
Like loopback, it is a purely virtual interface that allows packets to be routed to a designated IP address. Unlike loopback, the IP address can be arbitrary and is not restricted to the 127.0.0.0/8 range.
Example configuration
{
"name": "mynet",
"type": "dummy",
"ipam": {
"type": "host-local",
"subnet": "10.1.2.0/24"
}
}
Network configuration reference
name(string, required): the name of the network.type(string, required): "dummy".ipam(dictionary, required): IPAM configuration to be used for this network.
Notes
dummydoes not transmit packets. Therefore the container will not be able to reach any external network. This solution is designed to be used in conjunction with other CNI plugins (e.g.,bridge) to provide an internal non-loopback address for applications to use.
