mesh-lab/test/integration/whole-mesh-novox.test.ts

/**
 * The whole `novox` server's converted service set, installed together on ONE node behind the
 * foundation — the whole-catalogue install this rebuild has never actually run. First stage of a
 * whole-mesh rehearsal (novox/hq).
 *
 * Topology (proven by assigned-two-node-db.test.ts): the foundation (store, broker, control) rides
 * `anchor` and nothing else; ALL of novox's services ride the `novox` node. novox's own postgres
 * provider owns 5432 there, so it cannot co-locate with the foundation store. An overlay is placed so
 * each consumer's binding `at` resolves to novox's private address and reaches the providers
 * co-located with it.
 *
 * The SET (18 modules, all converted in mesh-catalog/modules/):
 *   providers   postgres redis minio mongodb mssql
 *   consumers   keycloak gitea nextcloud umami photos invoicing
 *   apps        portainer verdaccio registry route-proxy mailu
 *   node-level  firewall fail2ban
 *
 * Each committed module.json is LOADED from mesh-catalog — not hand-written — and its container
 * image references are rewritten to what this scenario's own registry serves by digest (the same
 * pinned(repositoryFor(image)) rule the two-node-db bed applies by hand). Two things this bed
 * discovered about the co-located set are handled at load time and RECORDED as findings:
 *
 *   HOST-PORT COLLISIONS. When the whole set lands on one node with its committed host publishes,
 *   several servers claim the same host port: nextcloud, invoicing-app and route-proxy all want 80;
 *   minio and invoicing-api both want 9000; gitea and umami both want 3000. route-proxy is meant to
 *   FRONT the web apps on 80/443, so the web apps' own host publishes are only for direct access.
 *   To let the whole set converge, the colliding web/app host publishes are remapped to distinct
 *   host ports here (container ports unchanged); the provider ports the consumers actually connect to
 *   (postgres 5432, minio 9000, mongodb 27017, mssql 1433) are left as-is. See REMAP below.
 *
 *   MESH_LAB_HOST_BINARY=.../mesh-host   MESH_LAB_BUNDLE=.../examples/foundation-first-node.lock
 * scripts/build-module-runtime.sh builds one runtime per module that has code; the route-proxy image
 * is built by scripts/build-route-proxy-image.sh; scenarios/whole-mesh-novox.yml stocks them all
 * alongside every server image.

 *             it needs ~2GiB and, with the whole set co-resident, the node is memory-starved. A

 *             so it exits, and the runtime dies "no photos API key". Not genuinely converted.
 *   mailu   — the manifest generates only secret/database/admin env; the Mailu images need their full
 *             configuration env (HOSTNAMES, DOMAIN, …), so every Mailu container dies rendering its
 *             template: "jinja2 UndefinedError: 'HOSTNAMES' is undefined" (and the resolver's
