The Production block never set one. inventory provision writes only
ansible_connection for a local host, so DOMAIN_PRIMARY stayed at the
group_vars default of infinito.localhost and the deployment served a zone its
own resolver knows nothing about. CoreDNS templates answers for
INFINITO_DOMAIN_RE and nothing else, so every lookup of the deployment's own
name came back NXDOMAIN.
Mastodon is where that surfaced. tootctl accounts create validates the address
through EmailMxValidator, which resolves MX and then, for the domain itself,
A and AAAA. All six queries returned NXDOMAIN in run 33574056480, the
validator recorded email :unreachable, and the admin account was never created.
Only the guide rows were affected: the matrix rows write
DOMAIN_PRIMARY: "{{ lookup('env', 'INFINITO_DOMAIN') }}" into their host_vars
and resolve fine.
The template now carries DOMAIN=<your-domain> in both the host and the
container form and threads it into --vars, with the container form passing it
through the docker run boundary as well. The two guide runners substitute it
the way they already substitute the SSH key, so the replay deploys under
INFINITO_DOMAIN like every other CI deploy. compose_deploy.sh moves its env
load ahead of the substitutions to have the value; host_deploy.sh had no env
load at all.
A production reader is asked for a domain now instead of silently inheriting
infinito.localhost, which no real deployment wants either. The shipped default
keeps its value: sys-svc-nss documents that *.localhost resolves through the
myhostname NSS module without any zone, and host-side tasks lean on it.

Asset Mirror (Privacy Proxy)
Description
Nginx is a high-performance web server and reverse proxy. This role wraps Nginx as a first-party mirror for the third-party assets other web applications declare in their CSP whitelists, so browsers fetch those assets from the deployment itself instead of contacting external hosts.
Overview
This role deploys an Nginx vhost behind the project's standard reverse proxy and exposes the canonical mirror service so that other roles can consume it through services.mirror.
The vhost proxies path-prefixed requests (/<origin-host>/<path>) to exactly the external origins aggregated from all deployed applications' server.csp.whitelist declarations; every other upstream is refused.
When an application enables the mirror service, the shared body filter rewrites the external asset URLs in its HTML responses to the mirror domain, and the CSP builder allows the mirror origin in the asset directives.
Cosmos
The diagram places Asset Mirror (Privacy Proxy) in the Infinito.Nexus cosmos: the components it deploys (capabilities), the central services it consumes (dependencies), and its outward reach (federation and bridged external networks).

Solid 1:1 edges are fixed relationships; dashed 0..1 edges are conditional (enabled only in matching deployments); red 0..0 edges are turned off in this role. Node markers show the role's deploy modes (💻 host, 🐳 compose, 🐝 swarm); ❌ marks a service that is explicitly turned off, and ⚙️ an Ansible role dependency declared in meta/main.yml.
Features
- First-party asset delivery: Browsers never contact third-party CDNs directly; the deployment fetches and caches assets server-side.
- CSP-derived allowlist: Proxy upstreams are generated from the applications' CSP whitelists, so the mirror can only reach hosts the deployment already trusts.
- Response caching: Mirrored assets are cached with stale-serving, keeping delivery fast and resilient against upstream outages.
- Tor-ready:
svc-net-tordepends on this service, so onion deployments serve all whitelisted third-party assets from the onion itself. - TLS-aware delivery: Runs behind the project's reverse proxy and inherits its certificate management.
Quick Setup
Development
Clone, set up the workstation, and deploy Asset Mirror (Privacy Proxy) onto the local stack:
git clone https://github.com/infinito-nexus/core.git
cd core
make onboard
make compose-deploy mode=reinstall apps=web-svc-mirror full_cycle=false
Production
Install Asset Mirror (Privacy Proxy) directly onto the target machine: clone the repository, install the OS prerequisites and the repository toolchain, then deploy against localhost over a local connection (no SSH, no container):
git clone https://github.com/infinito-nexus/core.git
cd core
bash scripts/install/package.sh
make install
source scripts/meta/env/load.sh
APP=web-svc-mirror
DOMAIN=<your-domain>
TLS_MODE=self_signed
SSH_PUBLIC_KEY="<your-ssh-public-key>"
INVENTORY=inventories/production
infinito administration inventory provision "$INVENTORY" \
--inventory-file "$INVENTORY/devices.yml" \
--host localhost \
--include "$APP" \
--vars "{\"TLS_MODE\": \"$TLS_MODE\", \"DOMAIN_PRIMARY\": \"$DOMAIN\", \"users\": {\"administrator\": {\"authorized_keys\": [\"$SSH_PUBLIC_KEY\"]}}}"
infinito administration deploy dedicated "$INVENTORY/devices.yml" \
--password-file "$INVENTORY/.password" \
--diff -vv
