NAME¶
podman-network-create - Create a Podman network
SYNOPSIS¶
podman network create [options] [name]
DESCRIPTION¶
Create a 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=<device> option.
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.
Special considerations for the netavark backend: - The macvlan driver requires the --subnet option, DHCP is currently not supported. - The ipvlan driver is not currently supported.
--gateway¶
Define a gateway for the subnet. If you want to provide a gateway address, you must also provide a subnet option. Can be specified multiple times. The argument order of the --subnet, --gateway and --ip-range options must match.
--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. Can be specified multiple times. The argument order of the --subnet, --gateway and --ip-range options must match.
--ipam-driver=driver¶
Set the ipam driver (IP Address Management Driver) for the
network. When unset podman will choose an ipam driver automatically based on
the network driver. Valid values are:
- host-local: IP addresses are assigned locally.
- dhcp: IP addresses are assigned from a dhcp server on your network.
This driver is not yet supported with netavark. For CNI the dhcp
plugin needs to be activated before.
- none: No ip addresses are assigned to the interfaces.
You can see the driver in the podman network inspect output under the ipam_options field.
--ipv6¶
Enable IPv6 (Dual Stack) networking. If not subnets are given it will allocate a ipv4 and ipv6 subnet.
--label¶
Set metadata for a network (e.g., --label mykey=value).
--opt, -o=option¶
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 options: - vlan: This option assign VLAN tag and enables vlan_filtering. Defaults to none. - isolate: This option isolates networks by blocking traffic between those that have this option enabled.
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.
--subnet¶
The subnet in CIDR notation. Can be specified multiple times to allocate more than one subnet for this network. The argument order of the --subnet, --gateway and --ip-range options must match. This is useful to set a static ipv4 and ipv6 subnet.
EXAMPLE¶
Create a network with no options.
$ podman network create 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 podman5
Create a network with a static ipv4 and ipv6 subnet and set a gateway.
$ podman network create --subnet 192.168.55.0/24 --gateway 192.168.55.3 --subnet fd52:2a5a:747e:3acd::/64 --gateway fd52:2a5a:747e:3acd::10 podman4
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 --subnet 192.5.0.0/16 newnet newnet
