I wrote a script to cross-reference podman --help against man pages. It found a bunch of inconsistencies fix them: * options missing from man pages * options misspelled or misformatted in man pages (usually misplaced asterisks or missing dashes, but see --dns-opt) * one spurious comma in the actual source file --help This is a fix in which I iterate over 'podman CMD --help' and check for presence in man pages. The other way around (look for flags in man pages, check podman CMD --help) is probably impossible: there are too many special cases Signed-off-by: Ed Santiago <santiago@redhat.com>

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 macvlan 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.
-d, --driver
Driver to manage the network (default "bridge"). Currently on bridge is supported.
--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
--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.
--macvlan
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.
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 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 --macvlan eth0 newnet
/etc/cni/net.d/newnet.conflist
