- unbound: add loopback DoH listener (127.0.0.1@8080, http-notls-downstream);
interface-automatic-ports lists 8080 so interface-automatic does not silently
drop the non-53 listener; access-control driven by resolver_allowed_netblocks
- caddy: add RedHat/COPR install path, caddy_template var, /var/log/caddy dir;
new Caddyfile-resolver.j2 terminates LE TLS and h2c-proxies to unbound,
enforcing the client allow-list via remote_ip
- resolvers: open 80/443 in firewall; prefer post-quantum SSH key exchange
(sntrup761x25519-sha512) via validated sshd_config.d drop-in
- bind9: zone.j2 emits AAAA records; add ipv6 for resolver1/2 (2606:1c80::240/250)
- playbook: run caddy role on the resolvers group
The previous role was netbox-community/netbox-docker (compose-based) but
the live host runs the upstream tarball install directly: system Postgres
17, system Redis 8, gunicorn under systemd, and Caddy reverse-proxy.
Re-running the old role would have torn the working install down.
This rewrite mirrors what's actually deployed:
- defaults: NetBox 4.6.0, /opt/netbox layout, gunicorn 5w/3t/120s, all
configuration.py knobs exposed as ansible vars.
- tasks: install OS deps, ensure netbox user, create Postgres role + db,
download + extract release tarball, run upgrade.sh, render
configuration.py / gunicorn.py / systemd units, enable services.
- templates: configuration.py.j2 covers the same keys the live file sets;
netbox.service / netbox-rq.service are byte-equivalent to the live
units (modulo paths driven by the install-dir var).
- caddy role gets a per-host Caddyfile-netbox.vntx.net.j2 mirroring the
live vhost (25MB body limit, /static/* file_server, reverse_proxy to
127.0.0.1:8001).
- inventory: new netbox_servers group; netbox.vntx.net added to
caddy_servers so the per-host Caddyfile is wired up.
- host_vars/netbox.vntx.net.yml: secrets reference vault_* vars; role
refuses to render config.py until they're set.
Operator action: create host_vars/netbox.vntx.net/vault.yml with
netbox_secret_key, netbox_db_password, and netbox_api_token_peppers
(value visible via `sudo cat /opt/netbox/netbox/netbox/configuration.py`
on the live host). See roles/netbox/README.md.
