+# Stoat — Fedora 44 self-hosted chat deployment
 
+Ansible automation that **hardens a Fedora 44 server**, installs **rootless Podman**, and deploys a self-hosted **[Stoat](https://stoat.chat)** instance (open-source community chat, formerly Revolt) using the official [`stoatchat/self-hosted`](https://github.com/stoatchat/self-hosted) stack.
+
+**Target host:** `stoat-demo`

+

+
+## Before you run
+
+1. **Set the real domain** in `group_vars/all/vars.yml`:
+
+   ```yaml
+   stoat_domain: chat.yourdomain.com   # ← A/AAAA record must point at the server
+   ```
+
+   Let's Encrypt certificates are issued for this name, and every URL Stoat advertises (web client, API, WebSocket, LiveKit) uses it. Do **not** use the public `stoat.chat` domain for your own instance.
+
+2. **Set the SSH user** in `inventory.ini`:
+
+   ```ini
+   stoat-demo ansible_host=stoat-demo ansible_user=YOUR_SSH_USER
+   ```
+
+3. **SSH password login is intentionally enabled** (`sshd_password_authentication: yes`).
+   - Root login stays disabled — use your SSH user + `sudo`.
+   - Fail2Ban is the brute-force defense: `3` failed attempts → `1 h` ban (tunable).
+   - If you ever want key-only auth again, flip the var to `no`.
+   - Ansible connects with a password via `-k`:
+
+   ```bash
+   ansible-playbook -i inventory.ini site.yml -k
+   ```
+
+---
+
+## What the playbook does
+
+| Stage | Actions |
+|---|---|
+| **System** | `dnf update` all packages; install `git`, `curl`, `openssl` |
+| **Firewall** | firewalld default-deny; allow `ssh`, `http`, `https`, `7881/tcp`, `50000-50100/udp` (LiveKit voice) |
+| **SSH** | drop-in `00-hardening.conf`: `PermitRootLogin no`, `PasswordAuthentication yes`; config validated with `sshd -t` before restart |
+| **Fail2Ban** | `sshd` jail (3 retries → 1 h ban, incremental for repeat offenders) |
+| **Auto-updates** | `dnf5-plugin-automatic`, security-only, `apply_updates = yes`, started timer |
+| **Logs** | logrotate rule for fail2ban logs (daily, 7 rotations, compressed) |
+| **Podman** | rootless engine + `podman-compose` + `podman-docker`; `net.ipv4.ip_unprivileged_port_start=80` so Caddy can bind 80/443; dedicated `stoat` service user with lingering enabled |
+| **Stoat** | clone `stoatchat/self-hosted` to `/opt/stoat/self-hosted`; run `generate_config.sh <domain>` (answers: built-in Caddy, video enabled); start stack under `podman-compose-stoat.service` |
+
+---
+
+## Network / ports
+
+| Port | Purpose |
+|---|---|
+| 22/tcp | SSH |
+| 80/tcp, 443/tcp | Caddy reverse proxy (automatic Let's Encrypt TLS) |
+| 7881/tcp | LiveKit WebRTC signaling |
+| 50000–50100/udp | LiveKit voice/video media (cannot be proxied) |
+
+---
+
+## Variables reference (`group_vars/all/vars.yml`)
+
+| Variable | Default | Meaning |
+|---|---|---|
+| `stoat_domain` | `chat.example.com` | **Required** — public domain for this instance |
+| `stoat_install_dir` | `/opt/stoat/self-hosted` | where the stack lives on the server |
+| `stoat_version` | `main` | git ref of `self-hosted` repo |
+| `stoat_reverse_proxy` | `false` | `true` = move Caddy to `:8880`, bring your own front proxy/TLS |
+| `stoat_video` | `true` | enable camera/screen sharing (LiveKit) |
+| `stoat_service_user` | `stoat` | unprivileged user running rootless podman |
+| `podman_unprivileged_port_start` | `80` | lowest port rootless containers may bind |
+| `fail2ban_port` / `fail2ban_maxretry` / `fail2ban_bantime` | `22` / `3` / `3600` | sshd jail tuning |
+| `sshd_permit_root_login` | `no` | root SSH access |
+| `sshd_password_authentication` | `yes` | password login (fail2ban guards it) |
+| `sshd_mfa_required` | `false` | only enable if a 2FA PAM module exists, else you lock yourself out |
+| `firewall_services` / `firewall_ports` | ssh,http,https / 7881, UDP range | firewalld allow rules |
+
+Override any variable per-run, without editing files:
+
+```bash
+ansible-playbook -i inventory.ini site.yml -k -e "stoat_domain=chat.example.org fail2ban_maxretry=5"
+```
+
+---
+
+## After deployment
+
+1. **First account = instance owner.** Open `https://<your-domain>` and register.
+2. **Make it invite-only** (recommended for a private instance): in `/opt/stoat/self-hosted/Revolt.toml` set `invite_only = true`, then restart the API service.
+3. **Back up `secrets.env`** — it holds the VAPID push keys, file-encryption key, and LiveKit credentials. Losing it means losing access to **all uploaded files** and breaking existing sessions. Copy it somewhere safe:
+   ```bash
+   scp stoat-demo:/opt/stoat/self-hosted/secrets.env ~/backups/
+   ```
+4. **Caddy terminates TLS itself** — do not put Cloudflare proxy (orange cloud) in front of the domain; ACME needs direct access to the server (grey cloud / direct DNS only).
+
+---
+
+## Day-to-day operations
+
+All commands run on the server, mostly as the `stoat` user (`sudo -u stoat` when needed):
+
+```bash
+# Stack status
+systemctl status podman-compose-stoat
+podman ps
+
+# Logs (per service: api / events / web / livekit / database …)
+sudo -u stoat podman logs -f api
+
+# Restart the whole stack
+sudo systemctl restart podman-compose-stoat
+
+# Update Stoat to new images (run in /opt/stoat/self-hosted as stoat)
+sudo -u stoat podman-compose pull
+sudo -u stoat podman-compose up -d
+
+# Fail2Ban status
+sudo fail2ban-client status sshd
+
+# Open firewall UI changes
+sudo firewall-cmd --list-all
+```
+
+---
+
+## Caveats & notes
+
+- **First start pulls ~2 GB of images** and initializes MongoDB — allow a few minutes; the systemd unit tolerates up to 15 min (`TimeoutStartSec=900`).
+- **Podman, not Docker**: the upstream stack is docker-compose based; this deployment runs it with `podman-compose` (rootless). It supports the compose features this stack needs (`depends_on: condition: service_healthy`, bind mounts, port ranges).
+- **`generate_config.sh` is guarded** by `creates:` — it never overwrites existing `secrets.env`/`Revolt.toml` unintentionally. To regenerate config deliberately, run it manually with `--overwrite` as the `stoat` user (after backing up secrets).
+- **Security posture**: rootless containers, non-root SSH user, fail2ban, firewalld default-deny, security-only auto-updates. (Aligned with the upstream guide's recommendations.)
+- **Rootless bind mounts**: data persists in `/opt/stoat/self-hosted/data/` (mongodb, rabbitmq, minio, caddy).
+- System hardening + Stoat are one role run; to re-apply only config changes, re-running `site.yml` is idempotent.
