--ip=ipv4

Specify a static IPv4 address for the <<container|pod>>, for example 10.88.64.128. This option can only be used if the <<container|pod>> is joined to only a single network - i.e., --network=network-name is used at most once - and if the <<container|pod>> is not joining another container's network namespace via --network=container:id. The address must be within the network's IP address pool (default 10.88.0.0/16).

To specify multiple static IP addresses per <<container|pod>>, set multiple networks using the --network option with a static IP address specified for each using the ip mode for that option.
