Lets a *multi-instance-capable* app run as several fully isolated instances
on one box (e.g. two Bookstack/WordPress sites, or a "family" + "work"
Nextcloud) — distinct data, DB, subdomain, backups and update cadence.
Design: an instance is just another app. It gets its own slug (<type>_<id>),
its own CFG_<SLUG>_* namespace, deployed dir, DB row, IP/port allocation and
host, so the entire existing pipeline (scan, install, services, routing,
updater, backups) treats it like any app with zero changes. All
instance-specific rewriting is confined to a clone of the type's template;
the shipped template and the core engine are untouched.
Gating: opt-in per app via CFG_<TYPE>_MULTI_INSTANCE=true. Only Bookstack
carries it for now (the validated reference). The other 31 apps are
unaffected — the feature is invisible unless the flag is present.
- scripts/instance/instance_create.sh — clone + re-namespace config, rewrite
compose identity (container_name / Traefik routers / backup labels) and
per-app tools, set a hostname-safe subdomain (PORT field 10), then hand off
to dockerInstallApp. Plus instanceList / instanceRemove.
- libreportal instance create|remove|list — new CLI category; mutations route
through the task system (no new mutating API endpoint).
- WebUI: "instance of <type>" badge + a "New instance" card action on capable
apps, and a create modal (name + domain# + subdomain, live host preview)
that dispatches the standard task. Capability/instance-of read straight off
the already-exposed app config.
Known follow-ups (documented): flip the flag on more apps after a compose
identity check (Nextcloud next); per-app tools are best-effort isolated.
