arguments needed for --net /run/netns/{ns}

[chnrxn]

I’d like to check what’s the correct arguments to supply to containers.run() to get the same effect as

podman run --net ns:/run/netns/ns1 ...

I have created a new network namespace with ip netns add ns1 and I'd like to create a new container using the Podman API to join this namespace. I successfully joined the name space on the command line with podman run -- net ns:/run/netns/ns1 but am not successful with the Python API client.

I tried network_mode=ns:/run/netns/ns1 but got an error Invalid network ns:/run/netns/ns1 instead. The documentation is not clear on this specific use case.
