 # hacc nixfiles
 
-welcome to hacc nixfiles (haccfiles). this is the code describing our nix-based infrastructure.
+Welcome to the hacc nixfiles (haccfiles). This is how we configure (most of)
+our infrastructure.
 
-## structure
+## General layout
 
-- `default.nix`: Entrypoint to the config
-- `common/`: configuration common to all hosts
-- `desktop/`: desktop-relevant communication
+- `flake.nix`: Entrypoint & dependencies
 - `modules/`: home-grown modules for hacc-specific services
-- `nix/`: sources files, managed with niv
-- `pkgs/`: packages we built and don't want to upstream
+- `pkgs/`: packages we need which aren't in nixpkgs
+- `websites/`: static websites hosted by us
+- `common/`: meta-level config, reusable across machines
+- `parsons/`: our sole server, its config & the services it runs
 
-## working with the haccfiles
+Right now, we only have a single host. We might add more again in the future.
 
-deploy:
-``` shell
-nix build -f . deploy.$hostname && ./result switch
+## Working with this repo
+
+You will need a flake-enabled nix installation, and have your ssh config set up
+so that `ssh parsons` will connect to `parsons.hacc.space`.
+
+### Deploying remotely
+
+It's recommended to use [deploy_rs](https://github.com/serokell/deploy-rs):
+~~~shell
+deploy .#parsons -k [--dry-activate]
+~~~
+
+Alternatively, using just `nixos-rebuild`:
+~~~shell
+nixos-rebuild --flake .#parsons --target-host parsons \
+  --use-remote-sudo --use-substitutes [test|switch|dry-activate]
+~~~
+
+### Re-deploying on parsons itself
+
+Simply do:
+~~~shell
+nixos-rebuild --flake .#parsons [test|switch|dry-activate]
+~~~
+
+## Working on websites
+
+Websites are exposed as flake outputs: if you're working on a website & want to
+check it in a browser, do e.g.
+
+~~~shell
+nix run .#\"muc.hacc.earth\"
+~~~
+
+to start a local http server (note that some of our websites need a directory
+to be built in; these use `/tmp/hacc-website`).
+
+To add a new website, add a new subdirectory to `websites`; nix will generate a
+vhost config based on that directory's name. Add a `default.nix` in your directory
+describing how to build the website, and give its derivation a `watch` attribute
+to make the `nix run` setup work.
+
+## I don't want to build this long dependency / want a cached version!
+
+If it's still available on parsons from a previous deploy, do:
+```shell
+nix copy --from ssh://parsons /nix/store/...
 ```
 
-`$hostname` can be replaced with any hostname or group
+Note: don't just copy the .drv file (which Nix complains about if it can't
+build something), that's just the description of how to build it! If you
+don't know the actual outpath, look in the .drv file (should start with
+`Derive([("out","[the path you want]"...`)
 
 ## committing to haccfiles
-- Golden Rule: DO NOT COMMIT TO MAIN
-  - exceptions apply, if you are not sure where to commit, don't commit to main
+- Things on `main` should always reflect the config that's actually deployed on
+  parsons, except during testing / debugging sessions
 - split up commits, every commit is one atomic change
-  - e.g. no big "did some changes" but instead "updated service x", "updated service y", "update service z"
-- follow the commit format: "$prefix$place: $change"
-  - prefix: one of fixup, nothing
-  - place: one of "modules/$module", "$hostname/service", "common/($place)", "pkgs/$pkgs" or "sources"
-  - change: describe your change, don't go over the character limit where git starts hiding/wrapping
+- follow the commit format: "place: $change"
+  - place: e.g. `modules/$module`, `services/$service` ...
+  - change: describe your change. Please wrap your lines sensibly (or configure
+    your editor to do this for you)
 - Exception: autogenerated messages (merge commits, reverts, etc)
+- don't overuse merge commits, try to rebase things if possible with reasonable
+  effort

+## Secret management
+
+We use [sops-nix](https://github.com/Mic92/sops-nix) to manage secrets which we'd
+like to have in Git but don't want to be public. Entries in `secrets.yaml` are
+encrypted for each of the age keys listed in `.sops.yaml`, which are themselves
+derived from ssh keys.
+
+For the initial set up, please take a look at the sops-nix Readme file.
+
+To edit the secrets file, run `sops secrets.yaml`, which will decrypt the
+file & open it in your $EDITOR, then re-encrypt it when you're done.
+
+To add a new key, use `ssh-to-age` to convert your ssh key to age, and add it to
+`sops.yaml`. Then do `sops updatekeys secrets.yaml` to re-encrypt the file for
+the new set of keys.

+hegedoc was once called codiMD, so container, config and users are still called codimd.
+
+**Do NOT change this** unless you're sure what you're doing.
+
+We have two instances:
+ - `pad-hacc`/pad.hacc.space is connected to our SSO/uffd
+ - `pad-i4f`/pad.infra4future.de is not connected to our SSO and meant to be more public
+
+## Basic Troubleshooting
+
+Usually if hedgedoc dies, it's because postgresql wasn't there yet. Just restart
+hedgedoc.
+
+## More Troubles
+log into the container and take a look at the logs
+
+~~~shell
+sudo nixos-container root-login codimd
+journalctl -e
+~~~
+
+### fixing failed database upgrades
+
+see https://docs.hedgedoc.org/guides/migration-troubleshooting/ (copied below
+for convenience?):
+
+In some cases, HedgeDoc might apply migrations without correctly saving the
+progress. It will then refuse to start with "already exists"-errors like
+ERROR: type "enum_Notes_permission" already exists.
+
+Get the name of the failing migration and append .js to it. For example, if
+you encounter this error:
+
+~~~
+== 20180306150303-fix-enum: migrating =======
+
+ERROR: type "enum_Notes_permission" already exists
+~~~
+
+the name of the failed migration would be 20180306150303-fix-enum.js.
+
+The SQL-statement may look like this:
+
+~~~
+INSERT INTO "SequelizeMeta" (name) VALUES ('20180306150303-fix-enum.js');
+~~~
+
+Make sure HedgeDoc does not run and insert the name into the SequelizeMeta table.
+Enter the container switch to the postgres user, open psql and commect to the
+codimd database:
+
+~~~shell
+su postgres
+psql
+\l
+\c codimd
+UN adjusted SQL STAMEMENT from above ]
+\q
+~~~
+
+Start HedgeDoc again and observe if it starts correctly. It may be necessary to
+repeat this process and insert multiple migrations into the SequelizeMeta table.

+Mumble's server is called murmur, but the naming is inconsistent. Sometimes
+it's also just called mumble server.
+
+# Usage
+
+## registration
+Users need to be registered to join any other channel than public.
+An already registered user has to register them with the server.
+1. right click on the username
+2. choose register in the menu. Done.
+
+## restricted channels
+Every channel in the hacc category except for plenum can only be accessed by
+members of the hacc group.
+
+## adding users to a group
+Only admins can edit groups, and only registered users can be added to groups.
+1. right click on the Root channel
+2. select Edit...
+2. In Groups select $groupname
+3. make the change you want to make
+4. click "OK"
+
+# Config details
+- the server is not registered with mumble & not on the public server list 
+- the bitrate is set to 128kb/s; otherwise the client would complain that the
+  server bitrate is less then the configured (default) in its local settings
+
+# Hacks
+- murmur needs a TLS cert, which we get via the ACME module
+- there's a funny group setup so that hopefully murmurd can read the cert
+- this seems to work fine now, but was some source of trouble in the past

+# Markdown docs with zola.
+
+[Zola](https://www.getzola.org/) is a static site generated written in Rust
+(which you'll notice since sometimes it panics).
+
+To run the site locally:
+
+```
+zola serve
+```
+
+## Directory Layout
+
+All the important stuff goes into `content`. If you create subdirectories, make
+sure you remembered to also create an `_index.md` file for it (if in doubt, just
+copy the one at `content/_index.md`); otherwise pages in there won't work.
+
+`templates` is *not* for site templates, but specifies how markdown files should
+be turned into html. If an autogenerated link broke, you'll probably have to
+change something in there. `sass` and `static` do exactly what they sound like.
+
+It usually shouldn't be necessary to change `config.toml`, but if it is, [here
+is the list of all available options](https://www.getzola.org/documentation/getting-started/configuration/).
+
+
+## File Layout
+
+Markdown files start with a frontmatter that should look something like so:
+
+```markdown
++++
+title = "blåhaj"
+taxonomies.categories = [ "flausch" ]
++++
+
+[actual markdown goes here]
+```
+
+The frontmatter is TOML; the `taxonomies.*` keys are special and can be used to
+aggregate posts if enabled in `config.toml` (currently that's only the case for
+`categories`, though). See also the [list of all available keys](https://www.getzola.org/documentation/content/page/).
+
+Please don't repeat the page's title in markdown, otherwise it'll appear twice
+in the html.
