Hi guys.
I suppose not since I see this:
-> $ podman container start alpine

Unfortunately, no. Rootless users don't have sufficient permissions to
use a conventional network stack. While we are not allowing CNI with
rootless Podman, this is for internal bridge networks only - it's
still entirely segregated from the host's network interfaces.

Unfortunately, no. Rootless users don't have sufficient
permissions to
use a conventional network stack. While we are not
allowing CNI with
rootless Podman, this is for internal bridge networks only
- it's
still entirely segregated from the host's network interfaces.

Thanks for clarifying - I do not suppose that is something
would change in the future?
And that also goes for: "portmap" (network rootless podman
creates by default) - when rootful, where there is "gateway"
will create a 'cni-podman0' iface whereas rootless does not
for is not capable, which is by design - right?

Thanks for clarifying - I do not suppose that is something would
change in the future?
Unlikely. There has been talk about using lxc-user-nic, a setuid
binary, to do some rootless network setup, which would give us some
elevated privileges; but even then, macvlan is not workable.
And that also goes for: "portmap" (network rootless podman
creates by
default) - when rootful, where there is "gateway" will create a
'cni-podman0' iface whereas rootless does not for is not capable,
which is by design - right?
Rootless containers joining CNI networks will have a network created,
but it's only for communicating with other rootless containers - the
host can't see it.
This is something that lxc-user-nic might be able to help with, though.
