node_exporter was listening on 0.0.0.0:9100 on helsinki-a and london-a,
exposing metrics to the public internet.
Changes:
- Add node_exporter_bind_tailscale flag (default false) to opt in
- Set flag on helsinki-a and london-a host_vars
- Debian: configure ARGS in /etc/default/prometheus-node-exporter
- FreeBSD: use native node_exporter_listen_address rc.conf variable
- Add handlers to restart on config change
Prometheus already scrapes via Tailscale IPs, no scrape config changes needed.
Fixes PESO-98
copenhagen-a had Ubuntu's docker-compose-v2 package installed, which
conflicts with Docker's official docker-compose-plugin over
/usr/libexec/docker/cli-plugins/docker-compose.
Moved the removal task before the install task and added docker-compose-v2
to the removal list.
* Add Docker official apt repo to docker role
The docker role was installing docker-compose-plugin which is only
available from Docker's official apt repository. helsinki-a had it
configured manually, but london-b and copenhagen-a did not, causing
deploy failures.
Now the role:
- Adds Docker's GPG key and apt repo (handles both Debian and Ubuntu)
- Installs docker-ce, docker-ce-cli, containerd.io, docker-compose-plugin
- Removes conflicting stock packages (docker.io, docker-compose)
* fix: resolve yamllint violations in docker role
- Remove standalone comment blocks that caused indentation errors
- Collapse multiline repo string to single line
- Ensure document start marker is present
* fix: keep all lines under 160 chars for yamllint
Use set_fact to build the Docker repo line in parts instead of
one long inline string.
* fix: resolve yamllint errors in london-b host_vars and promtail config
- Remove trailing blank line in inventory/host_vars/london-b.yml
- Add missing document start marker to promtail config
- Fix indentation in promtail scrape_configs (indent list items under key)
* Remove ansible-lint on push, keep PR-only
Lint already runs on pull_request — no need to double up on push to main.
Add the full media automation stack (sonarr, radarr, prowlarr, lidarr,
readarr, whisparr), media servers (jellyfin, plex), and supporting
services (transmission, samba, ollama, promtail, cloudflared, vsftpd)
to the repo as a media_stack Ansible role.
Includes:
- Custom systemd unit files for non-package-managed services
- Config files for promtail, samba, transmission, vsftpd
- Cron jobs for movie-rename-fix, sonarr/radarr midnight restarts
- Updated deploy.yml to wire the role into london-b's stage
- Updated london-b docs with full service inventory
Backup script (backup.sh) already covered by the existing backup role.
Node/systemd exporters already covered by existing monitoring roles.
Closes PESO-92
- New zfs role with cron-based scrub scheduling for Linux and FreeBSD
- Weekly Sunday scrubs at noon (matching existing manual crons)
- Add zfs_hosts inventory group with london-a and london-b
- Configure zfs_pools per host: zroot (london-a), hdd (london-b)
- Add Prometheus alert rules for degraded/faulted/offline pools
- Add zfs.yml playbook for targeted deploys
Captures the previously untracked scrub cron on london-a and
re-enables the commented-out scrub on london-b.

- Docker role: replace docker-compose with docker-compose-plugin (v2).
The old docker-compose package conflicts with docker-compose-plugin
already installed on helsinki-a. Also removes the conflicting package
if present.
- firewall_alpine handler: use ansible.builtin.shell instead of
ansible.builtin.command for iptables-restore, since the redirect
operator (<) requires a shell.
add status_page role that deploys update-status.sh and its cron job.
script queries prometheus for caddy upstream health and writes
status.json + history to /srv/status/ every minute.
refs: PESO-94
Add firewall_alpine role for Alpine hosts with iptables persistence
and fail2ban SSH jails. Wire it into nuremberg-a's deploy stage.
Mail ports are already exposed via Docker port mappings in the
poste-io docker-compose — this captures the surrounding iptables
and fail2ban config that was previously undocumented.
Closes PESO-96
* Configure UFW firewall rules in common Ansible role
Add UFW configuration to the common role for Debian hosts:
- Default deny incoming, allow outgoing
- Allow all traffic on tailscale0 interface (mesh comms)
- Allow SSH port 22 as safety net
- Per-host allowed ports via ufw_allowed_ports variable
- Enable UFW after rules are applied
helsinki-a gets ports 80/443 for reverse proxy traffic.
Other Debian hosts only need Tailscale + SSH.
Closes PESO-79
* Remove unused alerting and rule_files from prometheus.yml
Alerting is handled by Grafana, not Prometheus Alertmanager.
The empty alertmanagers and rule_files sections were just noise.
Resolves PESO-74
