podman-network-create - Create a Podman CNI network

podman network create [options] name

Create a CNI-network configuration for use with Podman. By default, Podman creates a bridge connection. A Macvlan connection can be created with the -d macvlan option. A parent device for macvlan can be designated with the -o parent= option. In the case of Macvlan connections, the CNI dhcp plugin needs to be activated or the container image must have a DHCP client to interact with the host network's DHCP server.

If no options are provided, Podman will assign a free subnet and name for your network.

Upon completion of creating the network, Podman will display the path to the newly added network file.

--disable-dns

Disables the DNS plugin for this network which if enabled, can perform container to container name resolution.

--driver, -d

Driver to manage the network (default "bridge"). Currently only bridge is supported.

--opt=option, -o

Set driver specific options.

For the bridge driver the following options are supported: mtu and vlan. The mtu option sets the Maximum Transmission Unit (MTU) and takes an integer value. The vlan option assign VLAN tag and enables vlan_filtering. Defaults to none.

--gateway

Define a gateway for the subnet. If you want to provide a gateway address, you must also provide a subnet option.

--internal

Restrict external access of this network. Note when using this option, the dnsname plugin will be automatically disabled.

--ip-range

Allocate container IP from a range. The range must be a complete subnet and in CIDR notation. The ip-range option must be used with a subnet option.

--label

Set metadata for a network (e.g., --label mykey=value).

--macvlan

This option is being deprecated

Create a Macvlan based connection rather than a classic bridge. You must pass an interface name from the host for the Macvlan connection.

--subnet

The subnet in CIDR notation.

--ipv6

Enable IPv6 (Dual Stack) networking. You must pass a IPv6 subnet. The subnet option must be used with the ipv6 option.

Create a network with no options

# podman network create
/etc/cni/net.d/cni-podman-4.conflist

Create a network named newnet that uses 192.5.0.0/16 for its subnet.

# podman network create --subnet 192.5.0.0/16 newnet
/etc/cni/net.d/newnet.conflist

Create an IPv6 network named newnetv6, you must specify the subnet for this network, otherwise the command will fail. For this example, we use 2001:db8::/64 for its subnet.

# podman network create --subnet 2001:db8::/64 --ipv6 newnetv6
/etc/cni/net.d/newnetv6.conflist

Create a network named newnet that uses 192.168.33.0/24 and defines a gateway as 192.168.133.3

# podman network create --subnet 192.168.33.0/24 --gateway 192.168.33.3 newnet
/etc/cni/net.d/newnet.conflist

Create a network that uses a *192.168.55.0/24** subnet and has an IP address range of 192.168.55.129 - 192.168.55.254.

# podman network create --subnet 192.168.55.0/24 --ip-range 192.168.55.128/25
/etc/cni/net.d/cni-podman-5.conflist

Create a Macvlan based network using the host interface eth0

# podman network create -d macvlan -o parent=eth0 newnet
/etc/cni/net.d/newnet.conflist
