this doesn't help us with anything yet, but it does at least mean that
this openssh now also listens on IPv6, which it didn't before.
(reaching the container from the outside still does not work)
this started with emily pointing out to me that it's possible to
generate IP addresses for containers in Nix (hence no need to worry
about ever having collisions, as we had before), but then I thought,
hey, while I'm at it, I can also write a little container module so we
have a little less repetition in our configs in general (and a more
reasonable place for our custom evalConfig than just keeping it around
in flake.nix).
See the option descriptions in modules/containers.nix for further
details.
Apart from giving all containers a new IP address (and also shiny new
IPv6 addresses), this should be a no-op for the actual built system.
mostly just replacing strings to avoid confusion later on. Since our
containers are now ephemeral, renaming them is basically a non-issue
(though the files under /persist/containers & the uffd client name had
to be changed manually)
this removes usage of the nftnat module by rendering it into a static
nftables config. It's a no-op (modulo /etc/haccfiles) as far as nix is
concerned, hence the slightly off-putting whitespace of the multi-line
string.
This seems to me to be a better approach than just bundling the module,
since we only use it for two things (giving the containers network
access & forwarding port 22 to forgejo), which to me doesn't press for
using a custom module we can't really maintain on our own.
the bind mount module has been tweaked in a couple ways:
- rename hexchen.* to hacc.*
- rename bindmount to bindMount to make it consistent with usage in
the nixpkgs container module
- add a hacc.bindToPersist option as shorthand for prepending /perist
to a path via bind mount
the nopersist module has been shortened a little by moving
service-specific things which are used once out into the individual
service files, and removing those which we don't need at all (this also
means we get to loose a mkForce or two in case of mismatches between
hexchen's and our current config).
