# Homeservers

This repository contains Ansible scripts to setup our home servers.
The `common` role executes some common OS tasks.
The `docker` role installs Docker.
The other roles are specifically for the various services we run.

## Running services

All services below are running under Docker, except NSD because I couldn't figure out how to enable IPv6 for it.

- Authoritative DNS using [NSD](https://www.nlnetlabs.nl/projects/nsd/about/) (ns.pizzapim.nl)
- Reverse proxy using [Traefik](https://doc.traefik.io/traefik/)
- Git server using [Forgejo](https://forgejo.org/) ([git.pizzapim.nl](https://git.pizzapim.nl))
- Static website using [Hugo](https://gohugo.io/) ([pizzapim.nl](https://pizzapim.nl))
- File sychronisation using [Syncthing](https://syncthing.net/)
- Microblogging server using [Mastodon](https://joinmastodon.org/) ([social.pizzapim.nl](https://social.pizzapim.nl))
- Calendar and contact synchronisation using [Radicale](https://radicale.org/v3.html) ([dav.pizzapim.nl](https://dav.pizzapim.nl))
- KMS server using [vlmcsd](https://github.com/Wind4/vlmcsd)

## TODO

### NSD

#### ZSK Rollover

Could make automatic key rollovers with cron or some other tool.

#### Idempotency

Currently I always resign zones.
But for idempotency I should probably only do it if the zone has changed or the keys have changed.

### Borg Backup

Ideal situation is to backup all of (and only) /data.
Issue with Mastodon: the cache is saved at /data as well. Should put this in a location that is not backed up.

After investigating, borg backup with borgmatic is excellent.
Instead of cron, I will use systemd timers to schedule borgmatic.

### Firewall

A little more difficult because of docker networking but probably doable.
