+### 19. InvenTree (Business-Apps) ✅
+**Date**: 2026-09-06
+**Application**: InvenTree — open-source inventory management (parts,
+stock, BOMs, suppliers, purchase/build orders, plugins, REST API).
+Upstream: https://github.com/inventree/InvenTree (MIT), v1.5.2.
+
+**Ticket**: [#658](https://projects.knownelement.com/issues/658)
+
+**Pattern**: official-image wrapper of `inventree/inventree:1.5.2`
+(amd64 digest pinned). Upstream compose splits server (gunicorn :8000)
+and worker (`invoke worker`); Cloudron is one container — worker
+backgrounded behind the web-port gate (NetBox pattern, third use).
+
+**Auth gate verdict**: ✅ OIDC preferred. django-allauth in core;
+`INVENTREE_SOCIAL_PROVIDERS` (settings.py:1002, JSON) carries the
+openid_connect provider; `SOCIALACCOUNT_OPENID_CONNECT_URL_PREFIX=''`
+routes SSO at `/accounts/oidc/<provider_id>/`. start.sh builds the
+provider JSON from `CLOUDRON_OIDC_*` with `server_url` (discovery) +
+PKCE. LDAP also in core as an alternative. Local admin seeded with a
+generated password persisted at `/app/data/.admin_password`.
+
+**Key decisions**:
+
+- Everything env-driven (INVENTREE_DB_*, INVENTREE_CACHE_* = redis
+  addon with cache DB 1, INVENTREE_SITE_URL, INVENTREE_ADMIN_*).
+- `invoke update` driven explicitly on every boot (migrations +
+  collectstatic); the image's init.sh ENTRYPOINT is bypassed so
+  ordering is ours.
+- Data dir pinned to /app/data — media/static/config.yaml/secret all
+  persist; the image's own SECRET_KEY_FILE convention then lives in
+  localstorage too.
+- Health endpoint: `/api/system/health/` (upstream's unauthenticated
+  probe path).
+- grind-stack fix: image names must be lowercase — dir basenames are
+  lowercased for tags/volumes (`grind-InvenTree:test` was invalid).
+
+**Verification** (grind-stack, ephemeral pg+redis): first boot ~7.5 min
+(migrations + static collection) → health 200; home 302→login;
+`/accounts/oidc/cloudron/login/` 302s to the issuer (provider JSON
+valid); worker gate fired; version-check JSONDecodeError in logs =
+release-API fetch noise (sandboxed network), benign.
+
+**Files Created**: Dockerfile, CloudronManifest.json (port 8000,
+localstorage + postgresql + redis, 2048MB, healthCheckPath
+/api/system/health/), start.sh, README.md, CHANGELOG.md,
+.dockerignore, logo.png (from repo docs/docs/assets).

+# InvenTree Cloudron Package
+#
+# InvenTree is an open-source inventory management system (Django):
+# parts/stock tracking, BOMs, suppliers, purchase orders, build orders,
+# plugin ecosystem. PostgreSQL storage + Redis for background-task
+# queues (RQ) and optional caching.
+#
+# Upstream: https://github.com/inventree/InvenTree (MIT), v1.5.2.
+#   - Official image inventree/inventree (single image; upstream compose
+#     runs inventree-server [gunicorn :8000] and inventree-worker
+#     [invoke worker] as separate services - Cloudron is one container,
+#     so start.sh backgrounds the worker gated on the web port, the
+#     same pattern as NetBox).
+#   - Everything is env-configurable via INVENTREE_* (config.md): DB,
+#     cache, site URL, secret key, admin seed, SOCIAL_PROVIDERS JSON.
+#   - The image ENTRYPOINT (init.sh) prepares dirs + config template
+#     and execs the CMD; migrations/static collection run via
+#     `invoke update`, which start.sh drives explicitly.
+#
+# Authentication: NATIVE OIDC (preferred) via django-allauth
+# (settings.py:1002 reads INVENTREE_SOCIAL_PROVIDERS;
+# SOCIALACCOUNT_OPENID_CONNECT_URL_PREFIX='' so SSO routes live at
+# /accounts/oidc/...). start.sh builds the provider JSON from the
+# Cloudron platform OIDC env (CLOUDRON_OIDC_*). LDAP also exists in
+# core (INVENTREE_LDAP_ENABLED) as an alternative. Local login remains;
+# the first admin is seeded (generated password, see README).
+#
+# Pattern: official-image wrapper. Image pinned by tag AND digest
+# (amd64 manifest digest of 1.5.2, from docker manifest inspect).

+# InvenTree — Cloudron Package
+
+[InvenTree](https://github.com/inventree/InvenTree) v1.5.2 — open-source
+inventory management: parts and stock, BOMs, suppliers, purchase/build
+orders, plugins, REST API. Django + PostgreSQL + Redis(RQ). Packaged as
+an **official-image wrapper** around `inventree/inventree:1.5.2`
+(digest-pinned). Upstream runs server and worker as separate compose
+services; Cloudron is one container, so start.sh backgrounds
+`invoke worker` gated on the web port (same pattern as NetBox).
+
+## Authentication (auth gate: ✅ OIDC preferred)
+
+django-allauth is built into core; `INVENTREE_SOCIAL_PROVIDERS`
+(settings.py:1002) carries provider config. start.sh builds the
+`openid_connect` provider from the Cloudron platform env:
+
+```json
+{"openid_connect": {"OAUTH_PKCE_ENABLED": true, "APPS": [{
+  "provider_id": "cloudron", "name": "Cloudron SSO",
+  "server_url": "<CLOUDRON_OIDC_ISSUER>", "client_id": "...", "secret": "..."
+}]}}
+```
+
+- SSO login route: `https://<app-domain>/accounts/oidc/cloudron/login/`
+- LDAP is also available in core (`INVENTREE_LDAP_*`) as an alternative.
+- Local login remains for the admin.
+
+**First-boot admin**: a local `admin` account is seeded with a
+generated password stored at `/app/data/.admin_password` (read it via
+the Cloudron file manager). Change it after first login, or set
+`INVENTREE_ADMIN_EMAIL`/`INVENTREE_ADMIN_PASSWORD` app env vars to
+control the seed yourself.
+
+## Runtime layout
+
+| Concern | How |
+|---------|-----|
+| Database | Cloudron `postgresql` addon |
+| Cache/queues | Cloudron `redis` addon (cache DB 1; RQ default DB 0) |
+| Schema + static | `invoke update` on every boot (migrations + collectstatic) |
+| Worker | `invoke worker` backgrounded, gated on web port (post-migration) |
+| Persistence | `/app/data` (localstorage): media/, static/, config.yaml, secret key, admin password |
+| Health | `/api/system/health/` (upstream's own unauthenticated endpoint) |
+
+## Notes
+
+- Version upgrades: bump tag+digest, rebuild — `invoke update` migrates
+  on first boot.
+- The image ENTRYPOINT's venv logic is bypassed (deps are baked in the
+  image); start.sh controls ordering instead.
+- Package pattern + verification: repo `JOURNAL.md`, InvenTree section.
