+# Server
+
+Configuration for traefik 2 and authelia
+
+
+### Authelia preprocessor
+The authelia configuration contains some sensitive values, but authelia cannot read them from env variables like traefic can.
+Instead, a special service - `authelia-config` runs before authelia start, and preprocesses the configuration file.
+
+- Local file `./authelia/configuration.yaml` is mapped to `/data/input` in `authelia-config`
+- Volume `authelia-config` is mapped to `/data/output` in `authelia-config`
+- `authelia-config` runs `gomplate` on `/data/input` and saves to `data/output/configuration.yaml`
+- `Volume `authelia-config` is mapped to `/etc/authelia` in `authelia`, where it reads its configuration
+
+## Lessons learned
+
+- Authelia will ONLY work with https. Both the authelia url itself and the one being authenticated must be https.
