% podman-network-create(1) ## NAME podman\-network-create - Create a Podman CNI network ## SYNOPSIS **podman network create** [*options*] name ## DESCRIPTION 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. ## OPTIONS #### **--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. ## EXAMPLE 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 ``` ## SEE ALSO podman(1), podman-network(1), podman-network-inspect(1) ## HISTORY August 2019, Originally compiled by Brent Baude
