Examples of how to do that with propellor +would be great to have! + +(There's a partial example in the haddock for +Systemd.publish, which uses networkd to auto-configure a private network, +but IIRC that is missing some routing/masqerading to let the +container access the internet.) + +As for `alias` and `ipv4` properties, when used in a container, their info +does get propagated out to the info of the host as of propellor 4.8.1. +That was done because it's sometimes useful to have an `alias` be part +of a container's configuration and get the DNS server automatically +configured with that alias pointing at the host(s) that have the container. + +I agree it does not make sense for `ipv4`/`ipv6` used in a container +to propagate out. I've changed propellor to not do that any longer, +and allow controlling whether any given DNS info should propagate or not. + +As for the hostname, it's not currently part of the Info system, +and so there's no risk of a container overriding its Host's name. +Things like Hostname.sane that look at the hostname will see the parent +host's name. Hostname.setTo should work in a container to give it +its own name. (At some point it would probably be worth moving hostnames +into Info to avoid the extra complication..) +"""]] |
