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.

# Elasticsearch
|
|
|
|
## Description
|
|
|
|
This Ansible role deploys and configures a central Elasticsearch search engine in a Docker container using Docker Compose. It is designed to simplify search administration by automating the creation of networks, containers, and per-consumer index namespaces (a role and user scoped to `<entity>-*` indices) for a secure and high-performance environment.
|
|
|
|
## Overview
|
|
|
|
Built for environments that demand reliability and ease of management, this role:
|
|
|
|
- Sets up a dedicated Docker network for Elasticsearch.
|
|
- Deploys a single-node Elasticsearch container with minimal security and automated healthchecks.
|
|
- Automates per-consumer provisioning (index-scoped role, user, and namespace) to streamline your workflows.
|
|
|
|
## Cosmos
|
|
|
|
The diagram places Elasticsearch 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`.
|
|
|
|
## Purpose
|
|
|
|
The purpose of this role is to provide an effortless way to deploy a central Elasticsearch engine via Docker so that application roles stay stateless, unpinned and NFS-shareable in swarm while the engine keeps its on-disk index state node-local. See [docs/architecture/central-engines.md](../../docs/architecture/central-engines.md).
|
|
|
|
## Features
|
|
|
|
- **Automated Deployment:** Installs Elasticsearch with minimal manual steps.
|
|
- **Per-Consumer Isolation:** Each consumer gets a role and user scoped to its own `<entity>-*` index namespace.
|
|
- **Enhanced Security:** The service is bound to `127.0.0.1:9200`, restricting access and enhancing security.
|
|
- **Seamless Docker Integration:** Works harmoniously with Docker Compose and other roles in your infrastructure.
|
|
|
|
## Quick Setup
|
|
|
|
### Development
|
|
|
|
Clone, set up the workstation, and deploy Elasticsearch onto the local stack:
|
|
|
|
```bash
|
|
git clone https://github.com/infinito-nexus/core.git
|
|
cd core
|
|
make onboard
|
|
make compose-deploy mode=reinstall apps=svc-db-elasticsearch full_cycle=false
|
|
```
|
|
|
|
### Production
|
|
|
|
Run the published image to provision the inventory and deploy Elasticsearch to a managed server (the mounted volume persists the inventory):
|
|
|
|
```bash
|
|
APP=svc-db-elasticsearch
|
|
HOST=<your-server>
|
|
DOMAIN=<your-domain>
|
|
TLS_MODE=self_signed
|
|
SSH_PUBLIC_KEY="<your-ssh-public-key>"
|
|
|
|
docker run --rm -it \
|
|
-v "$PWD/inventories:/etc/infinito.nexus/inventories" \
|
|
-e APP="$APP" -e HOST="$HOST" -e DOMAIN="$DOMAIN" -e TLS_MODE="$TLS_MODE" -e SSH_PUBLIC_KEY="$SSH_PUBLIC_KEY" \
|
|
ghcr.io/infinito-nexus/core/debian bash -c '
|
|
INVENTORY=/etc/infinito.nexus/inventories/production
|
|
infinito administration inventory provision "$INVENTORY" \
|
|
--inventory-file "$INVENTORY/devices.yml" \
|
|
--host "$HOST" \
|
|
--include "$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'
|
|
```
