nf network

The nf network command configures networks used for node provisioning and cluster communication.

Each network is bound to a specific NIC on the master node and defines a CIDR range, gateway, DNS servers, and optionally a DHCP range. When nodes PXE boot, they receive an IP from the configured DHCP range.

Use nf nics list to find available NIC IDs before creating a network.

Usage

Terminal

$ nf network list
$ nf network create --cidr <cidr> --gateway <ip> --nicId <nic-id>

Commands

nf network list

nf network list

List all configured networks with CIDR, gateway, DHCP range, DNS servers, and bound NIC.

Flag	Description
`--json`	Output results as JSON

nf network create

nf network create

Create a new network bound to a NIC on the master node.

Flag	Description
`--cidr`	Network CIDR, e.g. `10.0.0.0/24` (required)
`--gateway`	Gateway IP address (required)
`--dns`	DNS servers (repeatable)
`--rangeStart`	DHCP range start IP
`--rangeEnd`	DHCP range end IP
`--nicId`	NIC ID to bind the network to (required)

Examples

Terminal

$ nf network list NETWORKS: 1 (1 network)

ID CIDR GATEWAY RANGE DNS NIC a1b2c3d4 10.0.0.0/24 10.0.0.1 10.0.0.100 → 10.0.0.200 8.8.8.8, 8.8.4.4 eth0

Terminal

$ nf network create \
