move some options (the nopersist & container profiles + allowUnfree
packages) into the evalConfig used for containers, so we don't have to
repeat ourselves as much.
also removed some no-longer-needed specialArgs.
also made thelounge work with nopersist, which for some reason it didn't
use before.
in theory this might be ready to deploy. Potential hazards & things to
know when actually doing so:
1. the mysql version used by mattermost was updated (the old uses an
openssl which is marked insecure). Might have to migrate a database
2. lots of settings now use RFC 42-style settings, which might contain
new typos
3. this updates uffd (& changes the patches we apply). Since version
dependencies of uffd are basically "whatever debian has" we have
never bothered to match them, but afaik have also never updated uffd
since the initial deploy some years ago. No guarantee it still
works.
4. tracktrain depends on haskellPackages.conferer-warp, which is
currently marked broken. There is no reason for this (it builds
fine). Until fixed upstream, build with NIXPKGS_ALLOW_BROKEN=1.
cf. https://github.com/NixOS/nixpkgs/pull/234784; waiting for a
merge of haskell-updates into 23.05
this only concerns secrets which are in a raw file. Some of our
services (e.g. nextclouds) keeps secrets in its database; these remain
untouched.
Not yet deployed because of shitty train internet.
today i woke up to the realisation that there's an extremely obvious way
to make these nicer, & then i did exactly that. For some reason I did
not think of this when originally removing the dependency to nix-hexchen's
evalConfig.
unfortunately, this is not /quite/ a no-op. The only actual change is
different whitespace in some of the semantically-equivalent
coredns-configs that got unified.
this replaces niv with nix flakes, attempting to preserve the old
structure as much as possible. Notable caveats:
- I'm not sure if flake inputs expose version information anywhere, so
the version in pkgs/mattermost/default.nix is now hardcoded.
Confusingly, this appears to trigger a rebuild. Maybe I've missed something.
- a lot of the old-style host.nix & deploy.nix machinery in nix-hexchen
does not work with flakes, and their newer replacements are not exposed
by upstream; I've put basic imitations of the relevant parts in this repo
- (in particular, directories in hosts/ won't become deployable configs
automatically)
- parts of the code are now probably more complicated than they'd have to be
- old variables names were preserved; confusingly, this means the flake
inputs are still called "sources"
apparently the nixpkgs mattermost module simply ignores its own config
if mutableConfig is false, and reads whatever config is currently in the
database (in our case, old stuff involving auth.infra4future.de).
This overwrites that.
this does a couple things:
- redo mattermost's secret config as an env file passed to systemd
- get rid of modules/mattermost.nix and use upstream module instead
- move some of the stuff in secret.json which don't need to be there
into nix (e.g. smtp port)
Also, I set the log level to ERROR in the env file. Mattermost doesn't
seem to respect it otherwise *shrug*
