The lunar -> noble upgrade disabled every third-party repo on london-b, so
tailscale, jellyfin and plex have been frozen since. The common role can now
manage deb822 repos and clean up stale source/keyring files per host, and
london-b uses it for tailscale, jellyfin and plex (now on repo.plex.tv with
the v2 key). The dead sonarr v3, mono, nvidia, datadog and PPA leftovers go.
The first scheduled deploy failed on london-b because GitHub's gh apt
signing key expired on 2026-09-05. The common role now refreshes the
keyring from upstream wherever the github-cli repo is configured.
The proxmox_ve role was still writing a bookworm no-subscription source
onto hosts that are now trixie / PVE 9. I've switched it to a deb822
proxmox.sources using the host's release, and it cleans up the old
.list plus the enterprise repos in both formats.
copenhagen-c stopped reporting to Grafana Cloud on 2026-05-20: a transient
TLS failure to fleet-management tripped systemd's default start rate-limit,
systemd gave up, and the host sat silently unmonitored for ~2.5 weeks.
Add a 10-resilience.conf systemd drop-in for alloy.service on every host
(StartLimitIntervalSec=0, Restart=always, RestartSec=30) so a momentary
upstream/TLS blip can no longer permanently kill the collector.
Also drop the old self-hosted Grafana package that was left enabled and
failing on copenhagen-c after the move to Grafana Cloud.
cloudflared was retired in #56 when Caddy + Authelia replaced Cloudflare
Tunnels, but copenhagen-a was unreachable at the time so its
cloudflared.service was never stopped and is still running.
Add a cleanup task to the common role that stops, disables and purges
cloudflared wherever the unit lingers. Gated on the unit file existing so
it self-targets copenhagen-a and is a no-op everywhere else, and explicitly
excludes copenhagen-c, which legitimately runs a hand-configured tunnel.
Samba on london-b was allowed on 445/tcp from anywhere via UFW, exposing
SMB/CIFS to the public internet. Tailscale already reaches it through the
tailscale0 allow-all rule, so scope the explicit rule to the local London
LAN (192.168.1.0/24) instead of the world.
The common UFW task only ever adds allow rules, so it gained support for an
optional per-port from_ip, plus a follow-up task that deletes the superseded
world-open variant of any source-restricted port — otherwise the old
'445 ALLOW Anywhere' rule would linger on the host and defeat the change.
PESO-145
* 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
