--network-alias=alias

Add a network-scoped alias for the <<container|pod>>, setting the alias for all networks that the container joins. To set a name only for a specific network, use the alias option as described under the --network option. If the network has DNS enabled (podman network inspect -f {{.DNSEnabled}} <name>), these aliases can be used for name resolution on the given network. This option can be specified multiple times. NOTE: When using CNI a <<container|pod>> will only have access to aliases on the first network that it joins. This limitation does not exist with netavark/aardvark-dns.
