Deploy specific iptables ruleset for each container...

[Sebastián Maruca via Containers]

Hi to everyone!
Is it possible to deploy a "central" iptables ruleset at a Host,and then, deploy several "isolated" iptables rulesets, one for each container?
I'd like to have a this "central" iptables to chain basic rules,and each one of them have trivial rulesets, so as to speak of a"multi-tenant" IPTables.
Best regards,Seba

It depends what you mean by "deploy".  Firewall rule sets are 1:1 with
network namespaces, so it isn't possible to "inherit" rules from the
parent netns.  It is, however, perfectly possible to run a veth pair
between two different netns and apply different firewall rules on each
end with each rule set being in its own netns.  It sounds like this
could cover your use case.
