% 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 name of the newly added network. ## 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. Currently `bridge`, `macvlan` and `ipvlan` are supported. Defaults to `bridge`. As rootless the `macvlan` and `ipvlan` driver have no access to the host network interfaces because rootless networking requires a separate network namespace. #### **--opt**=*option*, **-o** Set driver specific options. All drivers accept the `mtu` option. The `mtu` option sets the Maximum Transmission Unit (MTU) and takes an integer value. Additionally the `bridge` driver supports the following option: - `vlan`: This option assign VLAN tag and enables vlan\_filtering. Defaults to none. The `macvlan` and `ipvlan` driver support the following options: - `parent`: The host device which should be used for the macvlan interface. Defaults to the default route interface. - `mode`: This option sets the specified ip/macvlan mode on the interface. - Supported values for `macvlan` are `bridge`, `private`, `vepa`, `passthru`. Defaults to `bridge`. - Supported values for `ipvlan` are `l2`, `l3`, `l3s`. Defaults to `l2`. #### **--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). #### **--subnet** The subnet in CIDR notation. #### **--ipv6** Enable IPv6 (Dual Stack) networking. ## EXAMPLE Create a network with no options. ``` $ podman network create cni-podman2 ``` 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 newnet ``` Create an IPv6 network named *newnetv6* with a subnet of *2001:db8::/64*. ``` $ podman network create --subnet 2001:db8::/64 --ipv6 newnetv6 newnetv6 ``` 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 newnet ``` 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 cni-podman5 ``` Create a Macvlan based network using the host interface eth0. Macvlan networks can only be used as root. ``` # podman network create -d macvlan -o parent=eth0 newnet newnet ``` ## SEE ALSO **[podman(1)](podman.1.md)**, **[podman-network(1)](podman-network.1.md)**, **[podman-network-inspect(1)](podman-network-inspect.1.md)**, **[podman-network-ls(1)](podman-network-ls.1.md)** ## HISTORY August 2021, Updated with the new network format by Paul Holzinger August 2019, Originally compiled by Brent Baude
